Installing windows 7 on a computer with uefi. How to configure the BIOS to boot from a disk or flash drive. Additional protection for Windows

Without an operating system, a laptop cannot work, so it is installed immediately after purchasing the device. Now some models are distributed with Windows already installed, but if you have a clean laptop, then all actions must be performed manually. There is nothing complicated about this, you just need to follow the instructions below.

UEFI replaced BIOS, and now many laptops use this interface. Using UEFI, you manage hardware functions and boot the operating system. The OS installation process on laptops with this interface is slightly different. Let's look at each step in detail.

Step 1: UEFI Setup

Disk drives are becoming less and less common in new laptops, and the operating system is installed using a flash drive. If you are going to install Windows 7 from a disk, then you do not need to configure UEFI. Simply insert the DVD into the drive and turn on the device, after which you can immediately proceed to the second step. Those users who use a bootable USB flash drive will need to follow a few simple steps:

1. Once you launch the device, you will immediately be taken to the interface. In it you need to go to the section "Additionally" by pressing the corresponding key on the keyboard or selecting it with the mouse.



and opposite the point "USB Support" set the parameter "Full Initialization".



2. In the same window, go to the very bottom and go to the section "CSM".



3. There will be a parameter here "Launch CSM", it is necessary to transfer it to the state "Enabled".



4. Now the additional settings will appear where you are interested "Boot Device Options". Open the pop-up menu opposite this line and select "UEFI Only".



activate item "Both, UEFI First". Next, return to the previous menu.



5. A section has appeared here. Go to it.



6. Against "OS type" please indicate "Windows UEFI Mode". Then return to the previous menu.



7. Still in the tab, go to the very bottom of the window and find the section "Boot Priority". Opposite here "Boot Option #1» indicate your flash drive. If you can’t remember its name, then just pay attention to its volume, it will be indicated in this line.



8. Click F10 to save the settings. This completes the process of editing the UEFI interface. Continue to the next step.

Step 2: Install Windows

Now insert the bootable USB flash drive into the slot or DVD into the drive and start the laptop. The disk is automatically selected first in priority, but thanks to the settings made earlier, now the USB flash drive will start first. The installation process is not complicated and requires the user to perform just a few simple steps:

The OS installation will now begin. It will last for some time, and all progress will be displayed on the screen. Please note that the laptop will restart several times, after which the process will automatically continue. At the end, the desktop will be configured, and Windows 7 will start. All you have to do is install the most necessary programs and drivers.

Step 3: Installing drivers and necessary software

Although the operating system is installed, the laptop cannot yet function fully. The devices lack drivers and also require several programs for ease of use. Let's look at everything in order:

Now that the laptop has the Windows 7 operating system and all the necessary important programs, you can safely begin to use it comfortably. After the installation is complete, just go back to UEFI and change the boot priority to the hard drive or leave everything as it is, but insert the USB flash drive only after the OS has started, so that the startup takes place correctly.

Current Windows 8.1 And Win10 before its predecessor Win7 there are many advantages, one of them is working with hard GPT -disks. GPT- this is a relatively new style of partitioning, the OS loads faster from such disks, they are more flexible to the data recovery procedure, and they can use the entire amount of disk space, if there is more of it 2.2 TB. Mandatory conditions for using benefits GPT : BIOS UEFI on computer, versions only Win8.1 And Win10, and only them 64 -bit releases.

The first and last conditions are a given and cannot be circumvented. But with Windows versions it’s not so tough. On GPT -disk in principle you can install the edition x64 "Sevens", however, not without nuances. Below we will talk about these nuances, and also look at the universal installation method Win7 to disk GPT , which will be applicable in most cases, as long as computers have BIOS UEFI. Or at least a hybrid BIOS with the support EFI software regarding loading from GPT -disks.

1. Win7 on GPT disks: nuances

To Win7 successfully installed on GPT -disk, in BIOS UEFI must be disabled Secure Boot – a function that blocks the device from starting from any uncertified software. Which, in fact, is the Windows 7 distribution.

If "Seven" install on an empty, not yet partitioned and not initialized hard drive in compatibility mode BIOS UEFI c Legacy, during installation the system will automatically create MBR -disk. And it is on him that the system will be installed. However, if in BIOS set strict parameters UEFI– only this mode of operation, while booting from a flash drive UEFI, in some cases installation Win7 on an empty disk can go exactly the same way as if we were installing system versions 8.1 And 10 . During this installation, the system itself will initialize the disk as GPT and will create the necessary for EFI - systems technical sections. And later when reinstalling "Seven" will stand on without any problems GPT - a disk with an existing partition scheme. But we are talking about only a part of the cases.

The key points in all this are the correct parameters BIOS UEFI and flash drive UEFI with installation process Win7. And if in the latter case there is a universal way out of the situation in the form of recording programs UEFI -flash drive, then in the case of settings BIOS UEFI There cannot be a solution suitable for everyone a priori. Here, of course, you need to understand each PC and laptop separately. However, install "Seven" on GPT -disk can be done without interfering with the settings BIOS, if only there instead UEFI or compatibility mode is intentionally not enabled in normal mode BIOS - Legacy. This option exists in the form of an alternative Windows installation mechanism, which is offered by the program. This alternative can also be used in case of implementation on motherboards of incomplete BIOS UEFI, and hybrid firmware compatible with EFI only in terms of support for downloading from GPT -disks and installation DVD, but does not allow booting from UEFI -flash drive.

Below we consider two installation cases Win7 on GPT -disk:

First- when we are dealing with empty SSD or HDD (or when the data stored on them is not valuable) ;
Second- when on GPT - the disk already has markings, in particular, there are technical sections EFI -Windows systems. This is an option without losing data stored on non-system partitions.

2. Bootable USB flash drive

To implement our plans, we will need a bootable flash drive with programs for working with disk partitioning. To do this, accordingly, it is necessary to prepare Live - a disk with all these tools on board. Perfect option - Live -disk WinPE10 TechAdmin. Its distribution in ISO The image can be downloaded for free here:

We write the downloaded image to a flash drive. To do this we use the utility Rufus. We indicate the flash drive in the first column, below we select the partition scheme - "GPT for UEFI computers". This is the mechanism for creating that same flash drive UEFI, which is fundamental for BIOS UEFI with selected mode only UEFI. If in BIOS Compatibility mode is present and active, you can select any scheme with a bootloader MBR . Then such a flash drive will become universal, and it will be possible to boot from it in Legacy on other PCs and laptops. Next we indicate the path to the image WinPE10 TechAdmin. And press "Start".

While the flash drive is being written, connect the installation ISO -image Win7 to display in Explorer.

Open the folder in the mounted drive "sources", and inside it we look for the file "install.wim"— installation WIM -image. As soon as the flash drive is written, copy it WIM -image and place it in the root of the flash drive.

This way we will have everything we need for installation on the flash drive. Win7. Indeed, in one of the methods described below, the disk on which the system will be installed will undergo repartitioning.

After placing it on a flash drive WIM - its weight will be approximately 5-6 GB. If it's a flash drive 8 GB, everything is fine. But if you only have a flash drive on 4 GB, after recording WinPE10 TechAdmin go to its root and delete the folder "AdminPE32" .

Now we look at the weight of the flash drive and figure out whether it will fit there WIM -image. If it still doesn’t fit, you can try to compress the image. Well, or download on the Internet an already compressed distribution kit with only the required edition "Sevens".

Boot from the newly created flash drive. Select download from .

3. Installing Win7 on an empty hard drive

So, the first installation method Win7 on GPT -disk is the case when we have either a clean SSD or HDD (without markings) , or when everything on them is not valuable and can be destroyed. On board WinPE10 TechAdmin launch the program.

Let's switch to the utility.

In the first tab "Physical disk" We indicate the desired disk, the one where we are going to install the OS. Next, click "Parts Management".

Then - .

In the window that appears, click the option "GUID". Next, check the options "Create ESP partition" And "Create MSR partition". Up in the block "Setting" remove values ​​from the top three blocks. Click "OK" at the bottom. We confirm the actions.

Created a diagram of technical sections EFI -systems consisting of ESP -partition with file system FAT16 And MSR -section. Let's assign it to the first ESP - section letter, we will need this later. Press , select a letter in the new window, click "OK".

Thus, using We have created the necessary partitions for Windows, but the rest of the disk space can be distributed in a more usable way - with the help of any of those present on board WinPE10 TechAdmin disk managers.

Here's a whole section WITH can be divided into two or more sections.

After this we return to the program. In the first column of its window we indicate the path to WIM -image on a flash drive. In the second, we choose ESP -the partition to which we gave the drive letter above, in the third - the partition itself Win7, i.e. future disk WITH . Below in the column we indicate the edition of the system. And press "Installation".

Next in the column we select "UEFI" on the right, on the left we make sure that the default value is set "Use BootSect...". If desired, activate auto-reboot upon completion of work . As a result, we press "OK".

Once this is complete, the computer will restart.

Now we need to boot from the disk where we just installed the OS. Next we will see the preparatory and configuration stages of installation.

4. Installing Win7 from a GPT disk with existing partitions

Installation "Sevens" for work GPT -disk - with existing markings, with technical sections EFI -systems (if you already had Win8.1 or Win10) , with data on other sections - it will be much easier. Here we need to run the program and, as in the previous case, specify:

Way to WIM-image,
Way to EFI-section;
Path to future disk WITH;
Editorial Win7, if the distribution provides several of them.

Where to get EFI-chapter? IN previous case using a section with the label has been created ESP. But Windows 8.1 And 10 during a normal installation, technical sections are created differently. It can be a diagram with two sections − EFI And MSR. Or maybe with three - EFI , MSR And WRE. In any case, we are only interested in the section EFI what's wrong with the file system? FAT32.

This is what needs to be indicated in the second column.

Specified program We format the sections. For the first EFI -partition, this is necessary so that the bootloader does not contain entries about non-existent operating systems. Finally, click .

We set the bootloader parameters and finally start the installation.

Developed more than 30 years ago, the basic BIOS input/output system is significantly outdated by modern standards. It is being replaced by the UEFI specification, which significantly changes the established and familiar boot procedure. This article is intended for those who are interested in installing Windows 7 on a computer with UEFI.

Replacement for outdated BIOS

Extensible Firmware Interface (extensible firmware interface) was developed by Intel in 1998. The current version of the specification is called Unified Extensible Firmware Interface. Computers manufactured after 2010 are highly likely to work with the UEFI system. Unlike BIOS, codes of the new specification can be stored both on the motherboard chip and in a special section of the HDD.

UEFI works with the new GPD partitioning, which is capable of supporting HDDs larger than 2 TB and an unlimited number of partitions. In addition, the UEFI architecture is modular and therefore supports custom applications and drivers.

And, the most important part for this article: the new specification has a built-in download manager. Thanks to this, installing Windows 7 from USB or external HDD does not require third-party bootloaders.

Creating a bootable USB flash drive

To create a bootable flash drive, the Rufus 1.4.3 utility is considered. The program is notable for the fact that it does not require installation, is very small in size and is distributed completely free of charge. Of course, Rufus supports GPT HDD partitioning and work with the UEFI specification. The current version of the utility is available for download from the manufacturer's official website.

After launching the utility, you must specify the name of the flash drive that will be bootable (Attention! All data from it will be permanently deleted!), file system (select FAT32), partition scheme and system interface (select GPT and UEFI). Opposite “create boot disk” you need to specify the path to the Windows 7 ISO image.

When all parameters are specified correctly, you can click on the “Start” button, and the process of preparing a bootable flash drive will begin. This will take some time, depending on the speed of your computer and the USB generation.

In addition to Rufus, you can use the WinSetupFromUSB program. It can also be downloaded from the manufacturer's website. The interface of these two programs is almost identical, so it makes no sense to consider the process of creating a bootable flash drive separately.

Installation Preparation

In order to start installation from a flash drive, you must first configure UEFI. To do this, you need to restart your computer and press F2 or Delete (depending on your motherboard, press both keys to be sure). After these steps, as in the case of the BIOS, you will be taken to the main control menu.

Press F7 or select the "Advanced" section. Next, go to the “boot” menu, select the “USB support” option and install Full Initialization. In the "secure boot" menu, set "windows uefi mode".

Now open the Compatibility Support Module (or CSM) menu and in the “launch CSM” item select “enabled”. Open additional options and in the “boot device options” select “uefi only”. This item will allow you to filter flash drives and HDDs that cannot work with your specification. In the “boot from storage devices” column, select “both, uefi first”.

Now all you have to do is specify the boot priority. Place the bootable USB flash drive in the first place, and your HDD in the second. The settings are completed, save them with the F10 key, confirm the decision, and the computer will restart.

Windows installation

If the previous steps were completed correctly, after the computer is rebooted, the standard installation of the operating system from the flash drive will begin. Click “next”, “install”, accept the user agreement, select full installation.

Now you need to open the command line using the combination Shift + F10. Next, enter the following sequence of commands:

diskpart (after each command you must press the enter button) sel dis 0 clean convert gpt exit

More details at this point. Using these commands, you will delete all data from the HDD, mark it as GPD and format it for subsequent system installation. Click "update" and "next".

The installation of Windows 7 on the HDD of your personal computer will begin. During the installation process, the PC will be rebooted several times, after which you will only need to specify its name and password, time zone and set a list of users. Once the installation is complete, Microsoft Update will download and install all the necessary patches and drivers, and you can use your computer.

UEFI mode - installing windows 7

Instead of the BIOS that is familiar to many at the moment, new motherboards for desktop computers and laptops are increasingly equipped with modern UEFI. Installing Windows 7 on such equipment is undergoing a number of changes. This factory software, unfortunately, is being implemented rather slowly and is currently not ready to replace the BIOS on the vast majority of boards, which entails a number of incompatibilities and problems with loading in the new mode. Most often, questions arise from people who want to install Windows 7 instead of the eighth version of the system that comes with a newly purchased laptop.

Is it worth switching to UEFI?

The main reason for switching from BIOS to UEFI was the lack of functionality, which is no longer enough for professional work computers that contain voluminous documents and require maximum performance of all components. It is worth noting that when loading the drive in UEFI BIOS mode, installing Windows 7 by default will not be possible on old MBR partitions. But there are two options for solving the problem.

The first is to copy all important data to an external or optional internal drive. The second is more labor-intensive and will require converting partitions using bootable flash drives or disks with utilities like Paragon, but will allow you to save all existing data, with the exception of the local disk with the system itself. In order to draw a conclusion about the advisability of installing a system under UEFI on your PC, you need to understand what advantages the new type of pre-installed software has in comparison with the previous one.

Old but effective BIOS

You can start your consideration with the Basic Input-Output System - BIOS, since this will be a logical sequence regarding the release time. The functions for which it is responsible are generally clear from the name. Basic software didn't appear overnight. As computer components developed, the BIOS itself progressed accordingly, thanks to which today people can use its wide functionality. Of course, core software alone could not meet all hardware needs. For this reason, programs and drivers were developed in parallel, configured directly in the operating system itself. However, the BIOS is responsible for such operations as initial hardware identification and determining the device from which to boot. It is very obvious that UEFI has similar functionality; installing Windows 7 and its correct operation on which will necessarily require the options described above.

Multifunctional UEFI

What is UEFI? If we decipher the abbreviation and translate it into Russian, the innovation is called Extensible Embedded Software Interface. The development of the system was started by Intel back in 2001 and was highly specialized in server equipment. UEFI was created due to the inoperability of Itanium processors with old firmware, since the kernel of the server computer needed significantly expanded functionality. Ordinary users saw the new product only in 2006 on board computers developed by Apple. Later, the innovation began to appear in the products of other companies, as indicated by the first word Unifed in the abbreviation. Among them there is both Microsoft, with its contribution to UEFI, under which the installation of Windows 7 was optimized by the company, and other software and hardware developers.

Advantages of UEFI when installing systems from Microsoft

Thanks to innovations, it is now possible to install Windows 7 on huge hard drives. GPT UEFI BIOS supports by default, and the system will be located under such a partition table. It is worth clarifying that the words “huge size” mean drives with a capacity of more than 2Tb. The old system only supported hard drives whose space did not exceed this mark. This is explained by the fact that the BIOS used the MBR partitioning to work with the drive, which contained the size of each record of 32 bits. From the calculations, a figure of 4 billion sectors is derived, which is exactly 2Tb. Even now, such a volume may seem excessive to some, but many 3D designers, not to mention employees using server equipment, have long needed such capacity. Thanks to UEFI BIOS, installing Windows 7, 8 and 10 can now be done on hard drives with a sky-high capacity of up to 8 billion TB.

Compatible with various equipment

Modern motherboards are equipped with software that supports both old hardware with MBR and new hardware with GPT partitioning. Now the user can choose the option that is most suitable for his computer. This was made possible thanks to UEFI dualbios support. Installation of Windows 7, 8 and 10 on such equipment will be available in two modes simultaneously, the choice of one of which is made by the user directly when booting from the drive.

Visual interface

Some developers not only introduced changes to the code, but also completely redesigned the interface, allowing for faster user interaction. Also another advantage was the ability to control UEFI elements using a computer mouse. This makes installing Windows 7 even more convenient and easier. You only need to get used to the new visual style once, and the desire to return to computers running BIOS completely disappears. Also, in the future, developers promise to create additional utilities for UEFI, even to the point that applications will be released that provide access to the Internet without installing an operating system. This task has already been partially completed, since the pre-installed software is updated via a network protocol.

Additional protection for windows

Another important point is the so-called secure installation of Windows 7. GPT UEFI is a new standard that will enhance protection on the Microsoft operating system. The utility can significantly reduce the chances of information loss and leakage. This option is enabled by default in the software, but can be easily deactivated in the settings if desired by the user.

UEFI Speed ​​and Orientation

Thanks to the redesigned basis, UEFI can significantly speed up Windows loading. It has become much easier to navigate the new interface thanks to bright and visually understandable content. Each category has an icon similar to those found in the operating system itself. There was also a utility section that had not been used until now. There are applications that allow you to view additional properties of your computer, such as installed hardware, temperature of elements, and much more. Of course, the specific set of utilities depends on the manufacturer and type of motherboard.

Transition from MBR to GPT

When switching from a system installed under BIOS to MBR disk partitioning, you should immediately think about saving important information. If this is not required, you can proceed directly to the installation. But in the case when there is data valuable to the user on the computer, it will be necessary to archive it or repartition the disk using specialized software.

Preparing USB with Windows 7 for installation on UEFI

Having studied the basics of working with the new software and deciding whether it is advisable to work under it on the current equipment, you need to start preparing for the process. Installing Windows 7 via UEFI will require certain skills in writing the system distribution itself. Users accustomed to using flash drives will need to be equipped with the latest version of Microsoft windows and one of the programs for burning the distribution to USB. As an example, one such program called Rufus will be presented.

After downloading the latest version of the application, you will need to select a flash drive with a minimum capacity of 4Gb. You must run Rufus as an administrator with “UAC” access rights confirmation. Going to the “Device” section, you will need to click on your flash drive to subsequently write the distribution kit to it. If you want to install the system with MBR or GPT disk partitioning, you must check the appropriate box. It is recommended to leave the default file system FAT32. At the next stage, you will need to select the ISO image of the system that was previously downloaded or purchased in a boxed edition and click the “Start” button. After the process is completed, the bootable USB flash drive for UEFI will be completely ready.

Booting from a drive in UEFI mode on various hardware

Of course, first you need to boot correctly, since this is strictly required by the UEFI installation of Windows 7. Gigabyte develops motherboards with Dual UEFI BIOS. On such equipment, before starting the process, you will need to go to the settings using the F9 key and select the appropriate operating mode. Similar steps can be performed on most motherboards from other manufacturers.

Fast boot in UEFI mode is also often used. To do this, you will need to call up the boot device menu and select a flash drive with the required mode tag attached (Lagacy does not have it).

If the user does not use the new BIOS, the desktop computer has the ability to completely deactivate it. It is worth noting that Lagacy Boot cannot be disabled in the settings, even when a UEFI installation of Windows 7 is performed. Acer is one of the developers who has completely removed the ability to deactivate any of the modes on their laptops, resulting in the need to use only fast boot to select.

It is very interesting that at first the new built-in security tools and partly GPT markup, when installed in the mode described above, blocked pirated cracks for the Microsoft operating system. Nevertheless, the hackers were quickly able to make corrections to their Windows 7 activator, the UEFI mode in which was already fully taken into account.

Having loaded with the method required by the user, further steps to install the system do not change.

The only thing worth noting is that when partitioning a disk, windows will now create a slightly larger number of additional partitions.

How to install windows 7 on uefi bios

Today, the BIOS system is considered outdated, and is gradually being replaced by a new version - UEFI. With it, installing the operating system takes on a different character, so many users encounter a number of problems during the process. In fact, there is nothing particularly complicated; I think that after the instructions given below, even a not very experienced computer user will be able to make friends with the UEFI BIOS specification. Actually, what to do if your computer has uefi bios, how to install windows 7 in this case, will be discussed further.

Creating a bootable USB flash drive

First of all, you need to create a bootable USB flash drive, and for this purpose I will use the Rufus utility. You, in turn, can use any other program, for example, WinToFlash or WinSetupFromUSB. So, here's what we do:

1. The Rufus utility must be downloaded from the developer’s website of the same name and then launched.
2. Set the name of the flash drive, select the file system (FAT32), system interface (UEFI), and finally select the path to the ISO image next to the “Create bootable disk” option.
3. After clicking on the “Start” button, the process of preparing a bootable flash drive will begin, which will take some time.

1. Reboot the system, click or.
2. In the control menu, click – “Advanced” - “Download” - “USB support” - “Full initialization”. Also open the "Secure Boot" menu and select "windows uefi mode".
3. In the CSM section, set “enabled” in the “Startup” item, and in “Boot device settings” - “only uefi”. For the “Boot from storage devices” option, click “both, uefi first”.
4. In boot priority, specify your bootable USB flash drive first, and put the HDD in second place.

Installing windows 7

After correctly following the above instructions, you need to restart the computer, which, in turn, will start the OS installation process from the flash drive. You are required to accept the license terms and choose to install the operating system completely. Next, open the command line using the + button combination, then write the commands that you see in the screenshot in the same sequence.

These steps will start installing windows 7 on your computer. During the process, the system will reboot several times, and at the end you will need to complete formalities, such as specifying the computer name, time zone, etc. After all drivers are automatically loaded, you can start working with your computer.

As you can see, nothing complicated, the main thing is to strictly follow the instructions. I hope everything works out for you!

Typical installation of Windows 7 on a laptop with uefi

• 1 What difficulties may there be
• 2 Installation

The BIOS system was developed more than 30 years ago. Many consider it an outdated type of software, which is gradually being replaced by a newer system called UEFI, which is widespread on modern computers. UEFI has a large number of useful functions (which include, for example, quite effective counteraction to computer rootkits). But at the same time, it can also cause a lot of trouble, since distributions of some operating systems launch on it with difficulty, while others do not launch at all. And installing or reinstalling one operating system instead of another is sometimes very difficult.

So, for example, you have a laptop with Windows 8 OS, which was installed at the time of purchase. But for some reason you decided to install Windows 7 as well. You try to do this in the usual way and discover that you cannot install one system instead of another, because the UEFI interface is installed on the laptop.

Very often, users wonder: is it even possible to install or reinstall Windows 7 on a laptop over Windows 8 if the laptop has UEFI? The short answer to this question is yes, it can be done. But what will it take? This is what we will talk about.

If you do decide to change your system or simply install one on top of the other (so that you can use both environments if necessary), then as a precaution you should definitely make a backup copy of the already installed system. Because recently, utilities designed for emergency OS recovery are practically not supplied by manufacturers in operating system kits. But if any problems occur, you may need to reinstall the previous system and only then try re-installing Windows 7.

What difficulties might there be?

So, what difficulties will a user face if he decides to change the operating system on a laptop with UEFI and install Windows 7 instead of the default Windows 8?

• Firstly, the BIOS has a UEFI-boot option, which is activated by default. It is responsible for the presence of a special service partition on the hard drive that supports the GUID Partiton Table (abbreviated as GPT). If such a partition is present in the system, then it will be impossible to install Windows 7 either from the original disk or from the image located on the flash drive. The following message will appear - Boot failure - a proper digital signature was not found. And if we were talking about a regular desktop computer, then there is a way to install or reinstall Windows 7 on a GPT disk. But in the case of a laptop, it no longer works.
• Secondly, if Windows 8 was previously installed on a laptop with UEFI, then the drive most likely already has a GPT table of contents. In this case, in order to install or reinstall Windows 7, you will need to convert the media instead of GPT to a more traditional Master Boot Record boot area (MBR for short). However, such a conversion can be done directly during the installation of Windows 7. More on this below.

Installation

Above we talked about problems with the UEFI-boot option. Therefore, before installing a new system on a laptop with UEFI, this option should be disabled. By the way, on some types of BIOS, instead of UEFI-boot, there may also be a Secure Boot option, which also needs to be deactivated. It is also advisable to take a closer look at the options with similar names, since there may be several options for the names of the options that are responsible for checking the compatibility of the bootloader certificate. Then all changes made in the BIOS should be saved.

Now let's move on to installing the Windows 7 operating system on a laptop with UEFI on top of the system already installed there. First, you will need a disk with the installer for this OS. Alternatively, you can create a bootable USB flash drive, from which you will then install the operating system. In any case, to start the installation you need to insert a disk or flash drive, open the boot menu and select the directory with the distribution from where the system can be installed or reinstalled. After this, the following message will appear.

Those who know English will understand that to start working, the system asks you to press any key on the keyboard.

After this, the Windows 7 installation wizard opens, with which you can either install or reinstall the OS. First, you can select the language, time format, keyboard layout, and then begin the installation by clicking the appropriate button.

When the installation wizard prompts you to select the drive on which the new operating system will be installed, you need to use the Shift and F10 key combination. After this, in the command line that appears, you need to do the following:

• Enter the diskpart command, then activate it by pressing the ENTER key;
• Enter the command disk list, press ENTER;
• Select the hard disk partition that is planned to be converted to MBR format;
• Enter the command select disk x (x - in our case this is the number of the selected disk), press ENTER;
• Enter the clean command, which will clean the disk and remove all unnecessary partitions;
• Enter the convert mbr command, which will begin the conversion to the new format, press ENTER;
• Enter the exit command.

After all the steps taken, you can close the command line window, and in the Windows 7 installation window asking you to select an HDD drive, you need to refresh the page (the corresponding link is in the wizard window). Now all that remains is to click “Next”, after which Windows 7 should be successfully installed on top of Windows 8.

If we need to reinstall Windows 7, we will again need a bootable USB flash drive or disk. The algorithm of actions in this case is similar to that described above, but you no longer need to convert the disk format.

How to install windows 7 on UEFI

Modern computers come with UEFI on board. UEFI is an interface between the operating system and firmware. Designed to replace BIOS. By the way, Apple has been using this technology for a long time. But this is not so important, the important thing is how to install W7?

Let's go in order. Let's say you have windows 8 (working or not) and you want to change it to windows 7. So.

First, you need to disable Secure Boot. This is a feature of UEFI - it prevents executable files or drivers from loading unless they are signed by one of the pre-installed keys.

To disable it, log into UEFI. When you turn on your desktop or laptop, press the “F2” or “Delete” key. In the “Boot” tab, change the “Secure Boot” value to “Disabled”. An additional item “OS Mode Selection” will appear, select “UEFI and Legacy OS” Now save the settings using the “F10” buttons, then select “Yes” and press “Enter”. The computer will begin to restart. Go to UEFI again. In the same tab, go to the “Boot Device Priority” parameter and in step 1, select the device from which you will install windows. Press “F10” again, then “Yes”.

That's it, the computer is ready to install Windows 7.

If, when installing on a new hard drive, Windows complains about the GPT partition style, then (after changes in UEFI): Insert the installation disk or flash drive, and after a while, boot into the Windows 7 installer.

Click install. We accept the license agreement. Select the full installation.

Call the command line using the combination “Shift + F10”. In the command line, enter the commands sequentially: diskpart sel dis 0 clean convert gpt exit

Click “Update”.

Now the continue installation button will be active. Click “Next”.

The Windows installation process will begin.

The BIOS system was developed more than 30 years ago. Many consider it an outdated type of software, which is gradually being replaced by a newer system called UEFI, which is widespread on modern computers. UEFI has a large number of useful functions (which include, for example, quite effective counteraction to computer rootkits). But at the same time, it can also cause a lot of trouble, since distributions of some operating systems launch on it with difficulty, while others do not launch at all. And installing or reinstalling one operating system instead of another is sometimes very difficult.

So, for example, you have a laptop with Windows 8, which was installed at the time of purchase. But for some reason you decided to install Windows 7 as well. You try to do this in the usual way and discover that you cannot install one system instead of another, because the UEFI interface is installed on the laptop.

Very often, users ask the question: is it even possible to install or reinstall Windows 7 on a laptop over Windows 8 if the laptop has UEFI? The short answer to this question is yes, it can be done. But what will it take? This is what we will talk about.

If you do decide to change your system or simply install one on top of the other (so that you can use both environments if necessary), then as a precaution you should definitely make a backup copy of the already installed system. Because recently, utilities designed for emergency OS recovery are practically not supplied by manufacturers in operating system kits. But if any problems occur, you may need to reinstall the previous system and only then try re-installing Windows 7.

What difficulties might there be?

So, what difficulties will a user face if he decides to change the operating system on a laptop with UEFI and install Windows 7 instead of the default Windows 8?

• Firstly, the BIOS has a UEFI-boot option, which is activated by default. It is responsible for the presence of a special service partition on the hard drive that supports the GUID Partiton Table (abbreviated as GPT). If such a partition is present in the system, then it will be impossible to install Windows 7 either from the original disk or from the image located on the flash drive. The following message will appear - Boot failure - a proper digital signature was not found. And if we were talking about a regular desktop computer, then there is a way to install or reinstall Windows 7 on a GPT disk. But in the case of a laptop, it no longer works.
• Secondly, if Windows 8 was previously installed on a laptop with UEFI, then the drive most likely already has a GPT table of contents. In this case, in order to install or reinstall Windows 7, you will need to convert the media to a more traditional Master Boot Record boot area (abbreviated MBR) instead of GPT. However, such a conversion can be done directly during the installation of Windows 7. More on this below.

Installation

Above we talked about problems with the UEFI-boot option. Therefore, before installing a new system on a laptop with UEFI, this option should be disabled. By the way, on some types of BIOS, instead of UEFI-boot, there may also be a Secure Boot option, which also needs to be deactivated. It is also advisable to take a closer look at the options with similar names, since there may be several options for the names of the options that are responsible for checking the compatibility of the bootloader certificate. Then all changes made in the BIOS should be saved.

Now let's move on to installing the Windows 7 operating system on a laptop with UEFI on top of the system already installed there. First, you will need a disk with the installer for this OS. Alternatively, you can create a bootable USB flash drive, from which you will then install the operating system. In any case, to start the installation you need to insert a disk or flash drive, open the boot menu and select the directory with the distribution from where the system can be installed or reinstalled. After this, the following message will appear.

Those who know English will understand that to start working, the system asks you to press any key on the keyboard.

After this, the Windows 7 installation wizard opens, with which you can either install or reinstall the OS. First, you can select the language, time format, keyboard layout, and then begin the installation by clicking the appropriate button.

When the installation wizard prompts you to select the drive on which the new operating system will be installed, you need to use the Shift and F10 key combination. After this, in the command line that appears, you need to do the following:

• Enter the diskpart command, then activate it by pressing the ENTER key;
• Enter the command disk list, press ENTER;
• Select the hard disk partition that is planned to be converted to MBR format;
• Enter the command select disk x (x - in our case this is the number of the selected disk), press ENTER;
• Enter the clean command, which will clean the disk and remove all unnecessary partitions;
• Enter the convert mbr command, which will begin the conversion to the new format, press ENTER;
• Enter the exit command.
