Installing OS via BIOS. Installing Windows from a USB flash drive via BIOS. What is the POST Self-Test Program?

So, first you need configure BIOS. To do this, turn on the computer and immediately press the key "Delete"(on some keyboards, short “Del”) on the keyboard until we get to BIOS(by the way, I almost forgot, your Windows XP boot disk should already be in your CD/DVD drive).

Your BIOS may look different. It depends on the manufacturer and. But don't be afraid, the settings are basically the same. In BIOS we will work with the arrow keys ←→↓ . So, we went into the BIOS, then go to the tab Advanced BIOS Features:

The name of the tab may be different in your BIOS. If so, then go through the tabs and find which one contains device boot options. In my case, this is what the device boot parameters look like:

Now our task is to make sure that the computer boots from the disk, i.e. on "First Boot Device" we will deliver CDROM. Let's do it like this (select the option opposite First Boot Device , press Enter on the keyboard and use the arrows to select CDROM):

It should look like this:

Maybe this confirmation will appear. Click "Y" on the keyboard, which means "Yes"(Yes), and press Enter:

Next there will be a reboot. We are waiting for such an inscription to appear "Press any key to boot from CD", which means « press any key to boot from CD« . Press any key:

And the installation program will start. After checking your system configurations, you will be given the option to Restore your existing system or install a new OS. Choose "ENTER=continue":

Then we accept the license agreement by pressing the button F8:

Then select the partition on which Windows will be installed. This is usually the section C:

Don't be afraid, click WITH:

Choose "Format partition in NTFS system":

Confirm with the key F:

File copying will then begin automatically:

After this, the computer will restart. Never click on "Enter - restart computer", otherwise the installation will be interrupted. Let the computer reboot itself:

After the reboot you will again be prompted to press any key, nothing don't press and then you will start the installation again.

After the reboot, the installation will continue, but in a more attractive environment:

Set the time, date, time zone and move on:

If this message appears, click OK:

Click again OK:

Select an item "Delay this action":

We write the account name. You can have up to five if there are several users:

That's it, the installation is complete!

Hope Windows XP installation was successful. All that remains is to install the drivers for normal operation of the computer. Good luck!!!

If you download an ISO image with a Windows distribution and even burn it correctly to a DVD or create a bootable USB flash drive using the same UltraISO, almost no one has any difficulty. Many people have difficulties with the second stage, directly installing the operating system from a disk or flash drive on a PC.
I know of three ways to start installing Windows.
1) the simplest and most unreliable is to open the image through a virtual drive with Windows already running and start the installation, but there are many factors that can interfere and give an error at some stage of such an installation.
2) Insert the flash drive we created into a USB connector or a DVD with Windows into your drive, no matter what version, whether Windows 7, Windows 10, even win95. This works for everyone. Then, when you turn on the PC, call the BOOT menu, this is a list with the media from which you need to boot, select the media you need and press ENTER. You can read more about how to install Windows via the BOOT menu here.
3) It differs from method 2 only in that we indicate what we want to boot from not through the boot menu, but in the BIOS of our device.
In this article we will talk in detail about how to install Windows from a flash drive via BIOS or boot Windows 7 from a BIOS flash drive.

Booting Windows 7 from a BIOS flash drive

When purchasing a new computer or laptop, as a rule, in specialized stores, the buyer can immediately take advantage of the paid service of installing an operating system on the purchased PC, as well as some programs, including anti-virus programs.

Working according to the standard scheme, the specialist in this case will install the default OS, without dividing the hard drive into partitions. As a result, the system local disk will contain the OS, a software package, and all kinds of multimedia files that are completely unrelated to the system.

And when the time comes for the next OS reinstallation, the user may forever lose all data on this computer. Of course, before this you can copy the contents of the disk to another medium, but you need to take into account that the decision to reinstall the OS is not always made in advance, as in the case of a sudden failure, the so-called “blue screen of death” (complete system failure without the possibility of its recovery).

Therefore, you should learn how to install Windows yourself. In fact, this is not as difficult as it might seem to a beginner, and even more so it will save money, gain the necessary knowledge in working with a computer and protect yourself from troubles with the loss of valuable information on your hard drive.

How to remove windows 7 and install windows 7: necessary steps before installing the OS

So, it is important to emphasize that during the installation process, immediately before changing the OS, all information located on the system local drive C will be erased. Therefore, the necessary data will have to be transferred either to another local drive or to an external storage device (CD, flash drive, removable drive or backup hard drive).

Accordingly, all files displayed on the desktop will also disappear, and the work of previously installed programs will be impossible in the future, since before installing a new OS, drive C must be completely formatted, thereby eliminating not only old data and system errors, but even unwanted, virus software, if any (and often it is viruses that cause system failure; in fact, they are developed for these purposes).

The next step is to have Windows OS (Windows 7 in this example) recorded as an image on the media. On the question of where to purchase this software:

• buy a licensed version at a computer store;
• download the OS distribution from the Internet;
• rewrite the OS image from another external media or borrow it for a while from friends.

You should immediately determine the bit depth of the operating system: 32 or 64 bit.

To find out which of them is currently installed, go to the Start menu - Computer - right-click on the general background - Properties.

Also, you need to write down or remember the total size of the local drive C and the amount of free space on it. This is done so as not to confuse the partitions with each other when reinstalling the OS.

Then, it is advisable to make sure that disks with drivers for the equipment are available (or driver versions may be stored on the PC, on another local drive).

A driver is the necessary software for launching and further stable operation of special PC equipment: input/output system (monitor; manipulators - keyboard, mouse, gamepad, etc.; sound and video card), external equipment (printer; scanner; uninterruptible power supply unit, etc. .)

If there are no drivers, you can successfully download them from the network even after installing the OS.

In case of reinstalling the OS, the user should know that Windows, recorded as an image on the media, gives the latter the name “bootable” (boot disk or bootable USB flash drive). And, since the operating system image is recorded in a special mode, the entire memory capacity of the bootable media is intended exclusively for Windows, and installation of the system is possible only through displaying and changing the settings of the “heart of the computer” - the BIOS.

The initial stage of installing Windows 7: BIOS settings

If the OS image on the bootable media has already been purchased and the system bit depth is known, then you can begin the installation process.

When working with a boot disk, we use the disk drive; if the OS is on a bootable USB flash drive, plug it into the appropriate USB connector and reboot the system.

As soon as the familiar title image of the motherboard logo appears on the monitor, we begin to repeatedly press a certain key to display the BIOS, most often it is the “Delete” or “F8” key. However, there are other options: “F1”; "F2"; "F3"; "F10"; "F12". In any case, in order not to waste time guessing the right button, just look carefully at the commands indicated at the bottom of the screen when the computer boots, where the “hot keys” for calling not only the BIOS, but also the general system management menu are located.

If the user did not manage to press the BIOS key at the right time, you should wait until the system boots and reboot it again, trying again. A successful press is accompanied by a special sound signal and displays the general BIOS menu on the monitor screen.

So, the BIOS menu has opened, now you need to select the “Advanced BIOS” item.

In the next window we find a list of priorities when loading the PC system, as well as connection statuses of individual equipment. In this list, it is important to select the primary priority column “First Boot Device”, opposite which is written “Hard Disk” (hard drive), that is, the settings determine that when the system boots, priority reading of information occurs through the hard drive data, in particular the registry and local drive WITH.

But in order for the PC system, bypassing loading the old copy of Windows, to start scanning and processing information from the boot disk, for this you will have to change the primary priority of reading data. We replace the “Hard Disk” request with “CDROM” if the image of the new copy of the OS is written to a CD and to “USB-HDD” if we are installing the operating system from a flash drive.

As for the older version of the BIOS, the changes in the settings are almost the same, although the overall appearance of the interface is different.

There is also an “Advanced” menu here, and switching the priorities for the primary reading of information is in the “Boot” menu.

Selecting a volume to install Windows 7

Now you should wait for the Windows 7 installation menu to appear while the system copies data from the boot disk.

As soon as it appears, select “Install Windows 7”;

architecture (bit size) - in accordance with the currently available one (or based on the performance of the processor and video card during initial installation);

installation type - complete;

We accept the terms of the license agreement.

In the menu that appears with partitions for installing Windows, by volume type and size, we find the one that is currently the local system drive C (just for this purpose it was necessary to record the volume of this disk before installation).

Let's start formatting it: select the required volume and click on the "Disk Setup" - "Format" button - in the warning message, click "Ok" and "Next".

Provided that the OS is being installed for the first time, in the menu with partitions, only one of the main volumes will be indicated with a size equal to the volume of the entire hard drive. In this case, using the “Disk Settings” button, you will need to delete this partition and in its place create a new one with a size of 100 GB, which will later become a system local disk. You should install a copy of Windows on it. The remaining large part of the hard disk capacity will fill the niche of another volume, which we will also create next to the first. Thus, we were able to divide the hard drive into partitions.

When you click on the “Next” button, the automatic process of unpacking OS files and installing components and updates will begin, which will take approximately 30 minutes until completion. Each further stage of installation will be accompanied by a reboot of the PC to save and accept the data.

Completing the installation of OS Windows 7

At the final stage, before the new copy of Windows 7 is displayed on the desktop screen for the first time, in the system settings windows that appear, you will need to enter: user name; OC product key; your account password, optional; interface language and keyboard layout. Next, the system will reboot again and then the desktop will open in a low resolution of 800*600 pixels. After this, you can remove the boot disk (or bootable USB flash drive).

Then, in order for all components and system updates to take effect, we find a shortcut with the Windows activator on the desktop and open it.

After activating the OS, we reboot the system manually and call the BIOS again, where we return the priority to the “Hard Disk” in the reverse order; save the changes using the “F10” key and confirm the actions with the “Y” and “Enter” buttons.

So, the new operating system is installed on the PC, all that remains is to connect the necessary drivers and update them to more recent versions via the Internet.

You can often see on the Internet the question “How to install Windows through the BIOS?” It makes an experienced user smile, but the essence of it is: what needs to be done in the BIOS to start installing the operating system?

First of all, we need to have an image of the installation disk with the Windows operating system. Then choose from what we will install our operating system (DVD drive / external DVD, or flash drive).

Now let's go directly to the settings in the BIOS. Depending on the manufacturer, after turning on the computer, press the Del, or F2, or F10, or Esc key to get into the BIOS settings (now there may be other combinations, you can find out which one you need to use from the equipment manufacturer).

Next, we need to find the Boot section in the BIOS, or Boot device priority, or Boot Device Configuration in which we will set the boot priority (what the system will boot from when turned on and in what order). Here you can install the first DVD drive (internal, external USB), flash drive or floppy drive (this is not a joke; in my experience, installing Win98 using 147 floppy disks)

Then you need to save the changes and restart the computer.

You can determine the BIOS settings for a specific motherboard by looking at them in the motherboard datasheet.
Important! Incorrect BIOS settings can damage your computer or reduce its power rating.

Information for management.
How to install Windows via BIOS, booting from DVD, USB, HDD depends on several Boot Menu keys

You need to get into the BIOS system: restart the PC and enter “Setup” - the software that is responsible for the initial boot of the computer.

During the reboot, carefully monitor the inscriptions on the monitor screen; you must not miss the line that appears at the bottom with the following text:
"Press ____ to enter SETUP."

The program tells you how to get into the BIOS, you need to press the key that is written on the screen, it can be:

F1, F2, F3, F10, Del, Esc - they differ on different computers, depending on the BIOS version.
Hold down the key until the system redirects to Basic Input-Output System. A list of tabs will appear on the screen; you need to select the one that talks about loading devices - “Boot devices” or “Advanced BIOS Features”.

If you fail to complete the prescribed steps the first time, do not despair; you need to repeat all the steps a couple of times.

We select a tab; in order to enter, you need to press the “ENTER” button. After that, find the “Boot Sequence” tab in the drop-down list and check the correctness of your choice with the information that appears on the right side of the monitor screen. It should say that the selected tab is responsible for the device boot priority.

After the boot tab has been determined, using the enter keys, you need to set the priority so that the first one in the list is “CD-ROM” or that boot device.

With the help of which the whole process will be carried out. To do this, you need to select “First Boot Device” in the list and then the hard drive.

You need to confirm that your choice is correct and click OK.

Thus, all BIOS system settings for loading and reinstalling Windows are ready. This was all done so that the next time the PC is rebooted, the OS itself will redirect Windows boot from the previously selected drive.

In order to start the download, you must restart your computer.

To install Windows via the Basic Input-Output System from a flash drive, in fact, the entire procedure is similar to that described above, but you need to select Secure Boot from the list of proposed tabs in the BB BIOS system, or in the OS, with the simple option of “overlaying” versions, select the appropriate menu item.

The process of installing Windows from a flash drive does not start and a black screen is shown on the monitor:

UEFI mode is enabled;
The flash drive is formatted in NTFS;
BIOS BB supports only NTFS, UEFI - FAT 32 partitions.
With a new version of the system to boot from a flash drive, it asks for permission to use automatic mode. It is best to refuse such an offer, otherwise the OS may be installed on the wrong partition or some of your personal files may be deleted.

Before setting the BIOS settings, you must select using “+” or “-” and click on the “Boot” tab.
When selecting settings, you must save them. To do this, you will need to press the “F10” - “Save and Exit” key. This action can also be performed by pressing the “->” key – “Exit Saving Changes”, i.e. “exit and save changes.”

After the approved and selected option and device boot priority, you need to select the F10 option, and then restart the computer.

For novice users who need to reinstall Windows via BIOS, experts have developed some tips for a competent and quick process.

For a successfully configured BIOS system, you should pay special attention to these recommendations:
PC requirements (subject to Windows 7):
Memory – at least 1 GB;
Processor – minimum 1 Hz;
Video card – minimum DirectX 9.
Time to work in the BIOS.

How long does it take to set up and configure a new version of Windows? It all depends on the technical parameters of the PC:

Performance “Clock Speed”;
Number of cores “Cores”;
Trunk frequency “800/1066/1333/1600 MHz”.
On average, it will take one hour to install Windows via BIOS.

Clean and simple Windows installation processes

A clean installation involves launching a disk with the system in manual mode while the computer is starting. After this, start, press any button, after the inscription “Press any key” appears on the tap.

The BIOS indicates the location of the new OS, for example, on a CD/DVD or hard drive, so that the old version is not used at all or is deleted. The clean version is used for any OS: Unix, DOS, Windows XP, as well as Linux, Windows 8 and Windows

Simple is rarely used and is not recommended. This is due to the fact that the new version is launched from a CD/DVD disk with the old OS already installed. So a simple installation is more like an “overlay” process, since the new version is overlaid on the old version.

Installation Process Difference

Easy installation of Windows:
Starting the computer;
BIOS;
Operating system;
BIOS;
Installation.

Clean installation:

Starting the computer;
BIOS;
Installation.
Clean installation.
Operating system hard disk partitions.

Often during a clean installation, all partitions are formatted and old versions and files are deleted. If you need to reinstall a system with several partitioned disks where important files are stored, you can leave the information unchanged.

It is not necessary to format drive D, however, drive C with files from the old version of Windows will be formatted.

Analysis of the hard drive during installation.

Before starting the Windows installation (if the OS is not working, crashes and glitches) you need to try to use the last chance of recovery and cleaning from malware.

If there are obvious problems with the operation of the PC, it is necessary, first of all, to check the condition of the hard drive, analyze the operation of the segments, otherwise, even during installation of the system, the formatting process may freeze or become unstable.

Saving personal information.

Personal data and information is a very important component that cannot always be restored if deleted or damaged, so before reinstalling anything, you need to take care of their safety.

To save information and personal data when reinstalling Windows, you need to copy and transfer all the necessary files to portable media (disk, flash drive, etc.). It is also very important to save passwords; for this it is recommended to use the Backup program or do it the old-fashioned way, manually.

By strictly following the rules and advice, you can understand how to install Windows via BIOS on a computer, even for a person without special skills and experience, in such situations.

Setting up BIOS under Windows 7

When setting up the BIOS to install any operating system, difficulties arise, since the versions may differ from each other. First, you need to enter the BIOS interface - restart the computer and until the operating system logo appears, press one of the keys in the range from F2 to F12 or Delete. In addition, key combinations can be used, for example, Ctrl+F2.

Further actions depend on the version.

AMI BIOS

This is one of the most popular BIOS versions that can be found on motherboards from ASUS, Gigabyte and other manufacturers. Instructions for setting up an AMI for installing Windows 7 are as follows:

Once you have entered the BIOS interface, go to the “Boot” item located in the top menu. Moving between items is done using the left and right arrows on the keyboard. The selection is confirmed by pressing Enter.

A section will open where you need to set the priority for booting the computer from certain devices. In the “1st Boot Device” item, by default there will be a hard drive with the operating system. To change this value, select it and press Enter.
A menu will appear with devices available for booting the computer. Select the media where you have the Windows image. For example, if the image is written to disk, you need to select “CDROM”.

The setup is complete. To save changes and exit the BIOS, press F10 and select “Yes” in the window that opens. If the F10 key does not work, then find the “Save & Exit” item in the menu and select it.

After saving and exiting, the computer will reboot and boot from the installation media will begin.

The BIOS from this developer is in many ways similar to the one from AMI, and the setup instructions before installing Windows 7 are as follows:

After entering the BIOS, go to “Boot” (may be called “Advanced” in some versions) in the top menu.
To move "CD-ROM Drive" or "USB Drive" to the top position, highlight the item and press the "+" key until the item is moved to the top.

Exit BIOS. Here, pressing the F10 key may not work, so go to the Exit option in the top menu.
Select "Exit Saving Changes". The computer will reboot and Windows 7 installation will begin.

There is no need to configure anything additionally.

Phoenix BIOS

This is an outdated version of the BIOS, but it is still used on many motherboards. Instructions for setting it up are as follows:

The interface here is presented as one continuous menu, divided into two columns. Select the "Advanced BIOS Feature" option.

Go to "First Boot Device" and press Enter to make changes.

In the menu that appears, select either “USB (name of flash drive)” or “CDROM” if installation is from a disk.

Save the changes and exit the BIOS by pressing the F10 key. A window will appear where you need to confirm your intentions by selecting “Y” or pressing a similar key on the keyboard.

This way you can prepare your computer with Phoenix BIOS to install Windows.

UEFI BIOS

This is an updated graphical BIOS interface with additional features that can be found in some modern computers. Versions with partial or complete Russification are often found.

The only serious drawback of this type of BIOS is the presence of several versions, in which the interface may be greatly changed, due to which the required items may be located in different places. Let's look at setting up UEFI to install Windows 7 on one of the most popular versions:

In the upper right side, click on the “Exit/Advanced” button. If your UEFI is not in Russian, then the language can be changed by calling the drop-down language menu located under this button.
A window will open where you need to select “Additional mode”.

An advanced mode will open with settings from standard BIOS versions, which were discussed above. Select the "Download" option located in the top menu. To work in this BIOS version, you can use the mouse.

Now find “Boot Option #1”. Click on the value set opposite it to make changes.

In the menu that appears, select the USB drive with the recorded Windows image or the “CD/DVD-ROM” item.

Click on the "Logout" button located on the top right side of the screen.
Now select the “Save changes and reset” option.

Despite the large number of steps, there is nothing complicated in working with the UEFI interface, and the likelihood of breaking something with an incorrect action is lower than in a standard BIOS.

You can install and reinstall, download, restore Windows using a flash drive, CD or DVD, and the correct actions during installation will lead to high-quality and fast results.

The BIOS is the foundation that is the input/output (I/O) base on the motherboard. Using it, you can configure certain parameters and adjust them on the computer. The I/O system may vary depending on the motherboard.

Step by step instructions

You can understand exactly what settings are in the BIOS by looking at the motherboard's passport. Incorrect BIOS parameters can reduce the power of a PC or completely destroy it.

Installing Windows from a flash drive or disk using BIOS depends on certain values ​​​​set in the Boot Menu.

Installation steps

So, all BIOS settings for installing Windows are ready. As soon as you restart your computer, the system itself will direct you to install Windows from the device you selected. In order for the installation to begin, you must restart your PC.

Possible problems

• There is a black screen on the monitor, nothing happens and the process of loading Windows via a USB flash drive does not work.
• UEFI mode is working.
• The flash card was formatted using the NTFS system.
• BIOSE only supports UEFI and NTFS partitions.

In the updated version of the BIOS, for installation from a flash drive, permission is requested to enable automatic mode. It is best to refuse this offer from the system, otherwise the software may load into the wrong partition that you need or may lead to partial deletion of your personal files.

Before you start setting certain parameters In the BIOS settings, you need to use the + and - keys to select the tab called Boot.

After the necessary parameters have been set, you need to save them by pressing the F10 key, which allows you to save and exit the system. You can also use a system parameter called Exit Saving Changes instead of F10 (that is, save the changes made and exit the system).

Once the boot priority has been set and all necessary parameter changes have been made and saved, you must reboot for the changes to take effect.

For inexperienced and novice users who need to install Windows using the BIOS, experts in this field have developed certain recommendations to ensure that the process is completed as competently as possible. In order to correctly configure the BIOS for installing software, it will be useful to carefully study these recommendations.

Requirements for your computer to successfully install Windows 7:

• Driver for DirectX 9 video card minimum
• Processor power 1 Hz minimum
• 1 gigabyte of memory minimum

The process of installing and configuring a new Windows will depend on the following parameters of your computer:

• Cores, that is, the number of cores in your PC's processor.
• Clock Speed, that is, the speed of your PC.
• Main frequency of your PC. You can have 1600, 1333, 1066 or 800 MHz.

The average installation time for Windows 7 or Windows 8 on most modern PCs is an hour of your time.

Types of installations

There is a “Clean Installation”, which involves starting the device with the Windows system manually when starting the PC. Next, start and press any key as soon as an inscription appears on the monitor called Press any key. After this, the process of specifying the location of the new software in the BIOS system occurs. For example, on a CD or DVD, so that the version that was installed before was no longer used or was deleted from the system. This “Clean Installation” option can be used with absolutely any operating system, for example: Windows 8, 7, XP, Linux, Unix or even DOS.

The “Easy installation” option is used quite rarely and it is not recommended for use, because the new OS is launched from media on an already installed “old” OS. Thus, the simple installation method involves superimposing a new version of the OS on the old one. During a “Clean Installation”, all partitions are formatted, as well as old files and OS versions are deleted.

If it is important for you to reinstall the system, while dividing several disks with important files, it is possible to leave these files unchanged. It is not necessary to format the D drive; however, the C drive with the old version of the operating system will be formatted.

In cases of a faulty operating system, before starting the Windows boot process, you should try to take the last chance to restore the system and clean it of various viruses and malicious software. If glitches and failures in the operating system are obvious, you must first check the hard drive itself , look at how its segments work. If you do not take this factor into account, the formatting process may freeze during the installation of a new OS or simply not work stable.

Saving personal data

Saving personal information and data is a rather important point when reinstalling the OS, since it is not always possible to restore data that has been formatted. For this reason, you should take care of the safety of your personal data in advance, even before the process of reinstalling Windows. In order to do this, you can copy all important programs, folders, documents and files on any portable storage device, for example, to a flash drive, disk, portable hard drive, etc. It will also be important to save passwords. To do this, you can use a program called Backup, or you can do it with a pen or pencil and a piece of paper.

Thus, following the instructions, recommendations and tips given here for installing new software through BIOS, it is quite possible, without any experience or special skills, to carry out all the installation processes yourself, without resorting to the help of familiar specialists or paid computer help. To install Windows correctly through the BIOS, it is important to accurately follow the steps in the step-by-step guide provided here. It would obviously not be amiss to also find some video courses that would more clearly demonstrate all these processes.
