Installing Windows via UEFI BIOS. How to configure the BIOS to boot from a disk or flash drive Installing Windows 7 in uefi mode

Developed more than 30 years ago, the basic BIOS input/output system is significantly outdated by modern standards.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Replacement for outdated BIOS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 place. 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 this 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 terms of recording 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 the 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:

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 the boot priority, first indicate your bootable USB flash drive, 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 item, 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 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.

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.

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).

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.

Enter the convert mbr command, which will begin the conversion to the new format, press ENTER;
Enter the exit command.

To avoid guessing, here's some advice for you:
— If your laptop has an MBR disk partition, then do it in Diskpart as usual
— If you have a GPT disk partition in your laptop, then do it in Rufus in GPT UEFI

Then you won’t make a mistake and you will be happy!!!

Deniska, apparently your BIOS is configured by default to boot from the extended version of Boot UEFI, which is supported only by Windows 8, 8.1, 10.
Windows 7 does not support booting from Boot UEFI Extended, for Windows 7 you need to downgrade Boot UEFI from Windows 8.1 Extended to Launch CSM. And to do this, you first need to disable the protection Secure Boot.
In addition, check that to download and install on a GPT disk, Windows 7 must be x64(64-bit).

Answer

aaalekseyyy 30.11.2015

Deniska, what can I advise you?

1. Lower the BOOT UEFI version in the BIOS to the minimum (If you have Secure Boot, then disable it first).

2. Go from some Live CD with Windows 7, initialize your disk in GPT and partition the disk. I do not recommend making large partitions, because, for example, for a 1 TB partition, in the event of information loss, just one pass of the Recovery program will take 17-24 hours, and to completely restore the information, it will take up to 3 days of continuous operation of the computer. It’s better to just create just one partition of 200-500 Mb, let the rest remain unallocated space, then you can further partition it as you need after installing the system.

More and more modern motherboards are built based on UEFI BIOS with support for the GPT partition style. The advantages of such a system seem to be obvious - faster loading, support for large storage devices, higher reliability and security. However, using a GPT disk is not suitable in every case. For example, if you need to install a 32-bit version of Windows. Also, if you are still not ready to take out a mortgage to purchase a Windows 7 license, then activating it using the usual means will be, if not impossible, then extremely difficult. Installing Windows 7 on a system with a motherboard running UEFI BIOS using the good old MBR will be discussed in this post.

The first step is to prepare an installation disk with Windows 7, or, if there is no disk drive on the computer, a bootable installation flash drive. For this I use the WinToFlash program.

The motherboard in my case was ASUS A88XM-A. Via F2 we go to the UEFI BIOS:

Switch to Advanced Mode:

And go to the tab BOOT where in the graph USB SUPPORT we exhibit FULL INITIALIZATION:

Going into it we set the following - Launch CSM - Enabled :

And in the column Boot Device Control - Legacy OpROM Only. Although, perhaps everything will work with UEFI and Legacy OpROM, I'm not sure and haven't checked.

And at the point OS TYPE choose OTHER OS:

Then we save the changes and exit the UEFI BIOS, booting from our installation media.

We go through the usual starting points of installation. If the disk was with the MBR partition style, then the installation should go without problems. If the disk has already been converted to GPT style, then it is necessary to convert it to MBR.

WARNING: During this operation, all data on all hard drive partitions will be destroyed!

This is done like this:

When you reach a screen that asks you to select a drive to install Windows, for example, this:

press the key combination SHIFT-F10 to go to the command line.

1. Enter the command diskpart

2. list disk— see a list of disks available in the system

3. select disk N- where N is the number of the disk that we are going to convert.

4. clean— complete disk cleanup with partition removal.

5. convert mbr— converting the disk to MBR.

Now on the partition selection screen, click “Update” and create partitions through “Configure Disk”.

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 done 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:

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.

"USB support"

"Full Initialization"

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

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

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".

"Both, UEFI First"

A section has appeared here. Go to it.

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

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.

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 for ease of use they also require several programs. 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.
