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 disc 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.
Unified Extensible Firmware Interface or UEFI is a firmware code that acts as an intermediary between computer hardware and the operating system, which replaced the BIOS with the release of Windows 8.
UEFI, like BIOS, is responsible for setting up and initializing devices when the PC is turned on and provides them with the ability to exchange data between themselves and the system. The UEFI functionality is focused on the most modern platforms - disk drives with GPT partitioning and 64-bit versions of the OS, mainly Windows 8 and Windows 7. But adherents of alternative, 32-bit and obsolete systems (like Windows XP) also did not lose the opportunity to “use” » favorite software, except that now installing it on the machine has become a little more difficult.
One of the main differences between UEFI and BIOS is a programmable interface, that is, it is a separate, small “OS” from which you can access the Internet and perform a number of administrative tasks (computer diagnostics, hardware configuration, running programs from CDs, platform update, etc.) to a much greater extent than can be done in the BIOS. Other important innovations are the graphical shell in which the mouse works and support for national languages.
BIOS also did not cease to exist with the release of the new platform - it “moved” to UEFI and, if necessary, can be launched - for this purpose, the new platform provides a BIOS emulation mode. Emulation is used specifically to support Windows XP and 32-bit versions of other operating systems.
Loading the operating system from a flash drive or bootable DVD
Just like old versions of BIOS, new versions of UEFI BIOS differ greatly from each other in design, location of tabs, settings and set of capabilities.
We especially note that a computer with UEFI can only boot from DVDs or media formatted in FAT32.
It is important to remember this when creating installation flash drives.
1. Load the BIOS. At the beginning of the computer boot, you need to start a special button for UEFI to appear:
ASUS/F2
ACER/F2
HP/Escape or F10
SONY / Assist button
2. For a better understanding, let’s turn on the BIOS display mode in Russian.
Open the list of languages in the upper right corner by clicking on the arrow opposite English.
Main window - select Russian language
(Picture 1)
3. If you are using a UEFI compatible flash drive, skip this step. To boot from a non-UEFI compatible device, you will need to disable Secure Boot.
Secure Boot is a security option that prevents the execution of boot code that is not signed by Microsoft.
Secure Boot is only supported by bootloaders for Windows 8 and some Linux distributions.
In many UEFI configurations, you must enable BIOS mode before disabling Secure Boot. This option is located in the “Boot” or “System Configuration” tab and can be identified by the words “CSM” or “Legasy”. The full name in different editions of UEFI is written something like this: “Launch CSM”, “Legasy BIOS”, etc.
(Figure 2)
In “stripped-down” UEFI, after enabling the BIOS mode, parameters that were not even displayed “by default” become available. Among them is Secure Boot, located in the “Security” menu or submenu. To turn it off, you need to switch it to “Disabled” mode. After this, the computer will be able to boot from a drive that is not UEFI compatible. Booting from USB is usually already enabled. 
(Figure 3)
4. Select boot from flash drive or DVD.
Press the “Boot Menu” button or F8 and in the “Boot Menu” dialog box that appears, select the device from which Windows will be produced.
(Figure 4)
If you select a hard drive or DVD drive instead of a flash drive, you can reboot again, go into the BIOS and change the choice.
5. To exit UEFI and save the settings, click the “Exit - Save Changes” button or click the item of the same name in the menu. The F10 key also works in BIOS mode.
If you select a download source, the system may not offer to save changes, but will immediately begin downloading from the device.
Uefi interface: tab navigation
In graphical versions of UEFI, the main window (Figure 1) usually displays the system time, platform information, and a number of hardware monitoring readings (device voltage and temperature, fan speed). To access the main settings, you need to switch to the “Advanced Mode” (F7) by clicking the button with the same name.
In the advanced mode of full-featured UEFI configurations, as well as abbreviated ones, the following tabs are present:
(Figure 5)
Main / Basic
Advanced / Additional
Security / Security
Boot
Tools/Service
Exit
Some others, such as Ai Tweaker or Monitor, are not available everywhere - mostly only on stationary motherboards. They provide access to utilities for overclocking a PC and system monitoring. Since mobile platforms (laptops) cannot be overclocked, these functions are not available on them.
Let's look at the parameters of the main tabs
a) Main
Here, as in the BIOS, the parameters of the main PC devices are displayed - processor, memory, drives, laser drives and others, as well as the system time and date. This tab contains the language selection option.
The submenu of connected drives displays detailed information about them.
Some of the Main section parameters can be toggled and configured, but not all.
b) Advanced / Additional
This section contains advanced PC hardware settings. Listed below are which ones.
Processor(s) details:
type;
clock frequency;
number of cores;
cache;
supported technologies, etc.
Plug and Play devices, configuration of SATA, video, PCI, peripherals, USB, integrated devices on the motherboard and peripherals.
In the absence of a separate “Power” tab, power supply parameters are configured in this section; in particular, energy saving functions and the behavior of the power supply in the event of a power failure are enabled here.
In the same section there is usually an option to reset hardware configuration data.
c) Security
Here you can find the option to turn Secure Boot on and off, as well as settings for access rights, passwords, etc. In some versions of UEFI, the Security section is present as a submenu of the Main tab.
The startup section contains:
option to enable BIOS mode;
order of polling boot devices;
Full Screen Logo - option to display the PC manufacturer's logo on the screen during POST;
Numlock Status - selecting the operating mode of the NumLock key during PC boot;
Boot-time Diagnostic - monitoring boot time and optionally a number of other settings.
e) Tools / Service
This frequently present but non-persistent tab contains the PC manufacturer's proprietary hardware management utilities. Here you will usually find a UEFI update option and a mini-browser that allows you to access the Internet to the manufacturer’s website.
f) Exit / Exit
This section can be in the form of a separate tab or button at the top of the screen. It contains various options for exiting UEFI:
Exit Saving Changes (save settings and exit);
Load Setup Defaults or Load default settings (restore default settings);
Exit Discarding Changes (exit without saving settings);
Discard Changes (cancel changes without exiting);
Save Changes (save changes without exiting).
Asus Ez Mode ( turn off “Advanced” mode and return to the main window)
What to do if UEFI changes make your computer run worse
Sometimes, after reconfiguring a number of UEFI parameters, the computer starts to work slower or refuses to load the OS at all. It can be difficult to remember what and where you changed with such an abundance of various options. To return everything to its place - restore the default settings, you can use one of the methods described below.
Load UEFI, open the “Exit” menu and click on “Load Setup Defaults”.
Disconnect the PC from the power supply, remove the cover of the system unit, find the CMOS battery on the board, remove it, short-circuit the terminals of the battery socket, and then return it to its place.
Find the CLRTC jumper on the motherboard (other names are CRTC, Clear CMOS, CCMOS, etc.), designed to reset the BIOS/UEFI settings. Place it on adjacent contacts and after half a minute return it to its previous position. Some boards have a special button for the same purpose.

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 ISO image of Windows 7.
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)
seldis 0
clean
convert gpt
exit
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.
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, it is necessary, 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:
- The Rufus utility must be downloaded from the developer’s website of the same name and then launched.
- 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.
- After clicking on the “Start” button, the process of preparing a bootable flash drive will begin, which will take some time.
- Reboot the system, click or.
- In the control menu, click – “Advanced” – “Download” – “USB support” – “Full initialization”. Also open the "Secure Boot" menu and select "Windows uefi mode".
- 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”.
- 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. 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 begin 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!
Progress does not stand still, new “tricks” are appearing to make life easier for users, and sometimes cause them headaches. The emergence of UEFI and GPT disks has become one of the problems that has complicated the life of those who want to independently install the OS on their computer. Let’s figure it out. In this article we will look at a “clean” installation of the system “from under BIOS\UEFI.” What needs to be done?
1.
You need to find out exactly what kind of boot interface your computer/laptop has, a standard BIOS or a new UEFI.
This can be found out by reading the specifications of the motherboard of your computer or laptop. UEFI also differs in appearance as more advanced, with colorful graphics and full-fledged graphic elements, more advanced settings, the ability to work with a mouse (not always), etc.
2.
You need to find out exactly what structure (style) your system disk has, MBR (Master Boot Record) or GPT (GUID Partition Table). All further actions will depend on this. Failure to clarify these points leads to unsuccessful installation of the system and loss of time.
To find out which drive is on your computer, right-click on the “Computer” icon and select “Manage”. In the window that opens, select the "Disk Management" tab, right-click on the disk (not the partition) and select "Properties" and go to the "Volumes" tab. The screenshots below show the differences between disks with different structures. All this is possible if your system is in working order. If the system is missing or damaged, then use boot programs such as Acronis or similar. The structure of the disk does not depend on which disk, SSD (electronic) or HDD (mechanical).
After finding out what kind of BIOS you have and what the hard drive structure is, the task of starting to install the operating system is divided into 3 different installation methods:
- installation from a classic BIOS on a standard disk with an MBR structure,
- installation of a UEFI (EFI) interface on a disk with an MBR structure,
- installation from UEFI on a disk with a GPT structure.
Important note. There is a misconception that in order to boot from bootable media, from a burned DVD/CD or from a created bootable flash drive, you need to go into BIOS\uefi and change the settings in the Boot priority list and put our media in first place. This is not only difficult, but also dangerous. It’s easier and more correct to use the hot key to call BootMenu with a list of available bootable media when you boot your computer and select the one you need. Every computer/laptop has such a key. A list of such keys is given below in the text. But in the list of priorities in the Boot settings of the BIOS or UEFI, the system hard drive should be the first, which reduces the system boot time and does not waste time searching for boot records from media we do not need.
As a rule, this installation method does not cause big problems for users.
We burn the installation ISO image of the OS to DVD using any program for working with DVD/CD discs. I recommend DVD+RW for recording as the most convenient and which can later be rewritten if recording errors are detected on it or when a newer version of the system is released. A prerequisite is to enable the disk check function after recording. Despite the fact that DVDs are gradually being replaced by other storage media, installing a system with DVD remains the most correct and basic installation method.
An alternative method is to install the system from the created flash drive. For installation “from under BIOS”, any available program for working with flash drives is suitable. For example, Windows7 USB DVD tool or Rufus or similar programs. See an example of creating a flash drive using Rufus below.
So, we create bootable media, install the media in the drive or insert a flash drive into a USB port, and reboot the computer. Now we need to boot from it. The simplest way is to call BootMenu, i.e. menu for selecting boot media using a hot key. This can be Esc, F2, F8, F10 or F12 (different keys on different computers, laptops).
In the BootMenu list, select the bootable media from which you intend to install the OS and proceed directly to the installation. As a rule, at the beginning of booting from the media, the message “Press any key to boot from CD” appears (press any key) or some kind of pre-boot menu appears, where we select system installation.
You can go a more complicated route. We go into the BIOS again using a hot key (the BIOS entry key is different from the bootmenu entry key), go to the boot media priority selection section (Boot) and install our media in first place. We save, reboot the computer and it should boot from our DVD or flash drive. Keep in mind that when installing from some media, the process may loop, i.e. Every time you reboot, we go back to the system installation. To fix this, after the first reboot of the computer during the OS installation process, you need to again set the priority to the hard drive.
If your media is not found in the bootable media selection list or does not boot from it, try restarting your computer again. If nothing happens after this, then most likely the DVD was not recorded correctly, with errors, or the drive does not read it. If the same thing happens with a flash drive, then you need to know that not every flash drive is suitable for such purposes, also some computers have protection against booting from USB, or the flash drive was not created correctly. The USB port may not be working correctly, especially usb3. Try switching from a port (connector) to a port with a usb2 interface.
After booting from bootable installation media, the process of directly installing the operating system begins, but changes on your hard drive do not occur until you select, delete, format, etc. manipulations in the window for selecting a location to install the OS.
Currently, the fleet of computers and laptops includes models with different versions of UEFI. The old version of this interface is not much different in appearance from the classic BIOS, but they contain sections and items with its (uefi) settings. The parameters and names may differ in different models, but the essence remains the same. By default, these uefi options are enabled and to install the system on an MBR disk we need to disable them. The designations will be different on different computers, usually “Secure Boot” or “UEFI Boot”, “Legacy (CSM) Boot”, “Launch CSM”, or “CMS Boot”, “UEFI and Legacy OS”, “CMS OS”. There is only one task: Secure Boot, UEFI Boot must be disabled (Disabled), and Legacy Boot must be enabled (Enabled). After performing these manipulations, installing the system is not much different from installing it under a regular BIOS. You can also go into BIOS\UEFI and set your bootable media as a priority, but it is better to call up the list of available bootable media using a hot key (see list of keys) and select the one you need. Please pay special attention to the list of media; as a rule, the same media will be present there, but with different labels, with and without the uefi label. For example DVD xxxx - UEFI and DVD xxxx, Flash xxxx - UEFI and Flash xxxx. You need to select exactly the line without uefi.
When installing a system under modern uefi with a full-fledged graphical interface, the media selection process is minimized. It supports installation on both gpt and mbr disks. Use a hot key to call up the list of bootable media (BootMenu) and select the one you need, but (attention!) do not make a mistake with your choice. Choose the one without the UEFI tag, as stated above. The same can be done by logging directly into UEFI and without changing the boot priority. Thus, modern UEFI starts working with bootable media already at the connection stage and adjusts to it, in which mode to boot from it, in normal mode or uefi mode. If there is no uefi tag on the boot media, then it will boot in standard “BIOS” mode.
This method (works when installing Windows 7, 8, 8.1, 10)
– When installing Windows, while at the stage (in the window) of selecting partitions, press the key combination Shift + F10. A command prompt will open.
Further:
Enter the diskpart command to launch the diskpart file utility
Enter the list disk command to display a list of physical disks connected to your computer.
Enter the command select disk N, where N is the number of the disk you want to convert.
Enter the clean command to clean out the disk.
Attention! All hard drive partitions will be deleted!
Enter the convert mbr command to convert the disk to MBR
or the convert gpt command to convert the disk to GPT.
Use the Exit command to exit diskpart
Use the Exit command to close the Command Prompt window.
Continue with Windows installation. To create new sections you need to click on the button
“Configure disk” in the window for selecting a partition for installing the operating system.
If you still do not want to convert the disk for some reason, then we burn the installation DVD of the system from the original 64-bit image or assembly that supports this installation method. Or we create a flash drive with a specialized program for working with bootable flash drives. The program parameters must be set to "UEFI and GPT disk" mode. The screenshot shows an example of how to do this in the Rufus program.
Loading from the created media is done in exactly the same way as described in the previous section (2), but exactly the opposite. In the old UEFI, you need to enable all the “Secure Boot” or “UEFI Boot” functions, and when selecting boot media from the BootMenu, select the line that contains the UEFI label. The same thing needs to be done if you want to change the boot priority in the UEFI itself in the appropriate sections. If your media (dvd/usb flash) does not have the UEFI label in the BootMenu list, it means it does not support this function and you will not be able to install the system from it to a GPT disk.
Additionally, the task is divided into installing the OS on " clean" and on "simple" installation from under an already installed system.
What is the difference between a “clean” and a simple installation from Windows...
Clean reinstallation of Windows- this is manually launching an already inserted installation CD/DVD disk or flash drive with Windows OS during the computer startup, pressing any key on the keyboard after the Press any key message appears on the screen. To do this, in the input/output system (BIOS), it indicates to the PC where the operating system is located, on the hard drive or CD/DVD, changes are made that allow you not to use the old operating system to start the installation and, finally, to completely remove it, by deleting all old partitions, creating new ones and formatting each new partition of the hard drive. This method will help you install Windows from any operating system (Linux, Unix, DOS, Windows XP) and is a guarantee of reliable PC operation. The disadvantage of this method is that after installation you will have to reinstall all drivers, programs, etc., and before installation, transfer and save the necessary data to a non-system partition or disk or other media. The method also requires increased attention when creating and deleting partitions on the disk, in order to avoid deleting the necessary user data. Still, this is the best method for installing an operating system.
"Easy" reinstallation- this is launching a CD/DVD disc with Windows with the operating system already loaded. Such an installation is not clean, since the old version of the operating system, which is usually infected with viruses, controls the launch of the installation of the new version of Windows and cannot remove itself. Viruses remain, and the new version is installed on the old one. This is, of course, the most convenient and simple installation method, but also the most unreliable, because errors and viruses of the old system can simply be transferred to the new one and the result will be disastrous. In addition, not every build of Windows OS supports this method. As a rule, system builders strongly recommend not installing the system in this way to avoid incorrect installation.
This article looked at "clean" installation of the system “from under BIOS\UEFI”.
