Why can't I install Windows? Solution to the error “Windows cannot be installed on this disk.... Possible problems with the hard drive

Often, novice users, to save time and money, do. A user who is doing the installation for the first time may encounter problems and may ask the question why Windows won't install?. Operating systems of the Windows family are very popular and now you need to know why they may not be installed.

Incorrect BIOS setting.

Any clean installation of Windows begins with preparing the computer. At this stage, when you try to install Windows from a disk or flash drive, problems appear and nothing is installed. For everything to work, you need to set for boot the device that will read the Windows media. For example, if the installation will be performed from a DVD/CD disc, then the first device to boot should be a DVD/CD drive with an optical drive (disk)
If you need it, then the first device to boot should be the flash drive itself, or rather USB HDD, USB Flash, USB Drive; also in the BIOS there may be a signature based on the name of your flash drive or something similar, depending on the BIOS firmware version and the model of the computer's motherboard. Before saving the selected settings, you need to make sure that the floppy drive is disabled. You need to go to the “Standard CMOS Features” section, where you need to disable “Floppy - 1.44 or Drive A”. Next you need to save the settings, press F10 and YES. The computer will reboot and the system will begin installing Windows from the disk or flash drive.
Even when installing from a flash drive, problems may arise with the type of use of the hard drive. On modern computers, the hard drive can operate in IDE AHCI and RAID modes. If you don’t have a raid array of disks, then let’s look at the remaining settings. You can find these settings in the IDE configuration section. I recommend using AHCI mode, but when installing Windows from old flash drives, a message about the absence of a driver may appear. If you have such a problem, switch to IDE mode and then the installation will proceed without errors. Learn more about BIOS settings.

A broken system image or damaged media.

Another persistent problem is the incorrect image capture from Windows. A bad disc (blank disc), a damaged DVD/CD drive through which Windows was recorded. The same can happen with a flash drive - bad memory or faulty USB ports on the mainland. It also happens that the equipment is in good working order and works correctly, but the image itself is damaged initially even before the moment of recording, for example, it was under-downloaded or was even damaged when uploaded to the site. In this case, you need to have several Windows images on hand, on different drives. You can try installing the operating system using another drive, for example an external one. Use different Windows installation methods and devices to achieve your goal of installing Windows by elimination.

The computer hardware is damaged.

Another problem is computer hardware failure. This could be a damaged motherboard, video card, hard drive, RAM, power supply, or processor.
It is necessary to carry out. Identify the damaged part and replace or repair it. There are many tests for this that do not require an OS. You can check the motherboard, processor and video card using the PC Test utility. The hard drive can be checked with the HDD Regenerator program. RAM using the MemTest utility. The power supply can be checked through the BIOS or simply physically.

Outdated PC hardware

Here I think everything is clear, if the computer hardware does not meet the minimum system requirements for installing Windows, then you will not be able to install it. For example, to install Windows 10, you must have at least 1GB of RAM on your computer, at least 16GB of hard drive space, and a processor frequency of at least 1 GHz. The video card must support DirectX 9.0c. It is clear that such a computer will not be able to provide comfortable work. Therefore, for normal operation you need a multi-core processor with a frequency of more than 1.6 GHz and 2 GB of RAM. Sometimes all parameters may be suitable except the video or sound card. For example, many still have ATI Radeon x700 video cards with 256 or 512 MB of memory. It seems that the video cards are not very old. But they don't have DirectX 9.0c support. They support DirectX 9.0b but can no longer run on Windows 8, 8.1 and 10. Carefully review all the specifications of your computer before installing Windows to ensure it meets the system requirements. And if they are suitable, only then start the installation.

What else could be causing Windows to fail to install?

Old BIOS of the motherboard or video card. Update them.
Disconnected cable or power, check the connections of all cables and cables.
Conflicting parts – network cards, sound cards, TV tuners and the like.
Windows builds, many download operating system builds and try to install them. Such operating systems often simply cannot be installed on certain computers. Use clean original Windows images for installation and then you should not have any problems.

I have a good friend Ruslan, he had a normal desire to use Windows XP on his home computer . He is an advanced user, why not, the computer is powerful, the hardware is 100% suitable. Buying a seven in our time is naturally not a problem, which is what we did, we decided to carry out the installation process together.We came to him, took out a beautiful disk from a bright box, and inserted it into the disk drive. My friend’s hard drive is divided into two partitions, the first drive (C:) has a capacity of 120 GB, the minimum for installing the seven is 20 GB. Windows XP is installed on it, there is also a disk (D:) with personal data, we decided to install Windows 7 on (C:) and everything that was valuable on it was copied to (D:). Everything is ready for installation. Just in case, I went to Disk Management and made sure that the disk was converted to , since the seven will not work on dynamic without general formatting.

Windows 7 won't install because the second screen is disabled

Rebooted, went to . We set the disk drive as the first boot device, the hard drive as the second, I turned off the floppy drive completely, since the computer often wants to boot from it, everyone has nostalgia.

• Note: Friends, if you are, then you should know that Windows 7 does not support USB 3.0 (ports are usually colored blue), if your flash drive is USB 3.0, insert it into a USB 2.0 port.
• And some more information for you, if this article still doesn’t help you, try going all-in and read our article.

The Windows 7 installation process has begun, which does not foretell any problems, my friend’s computer is good and still under warranty. In the window - Select a partition to install Windows, select the first partition with Windows XP, delete it and click next, copying Windows files begins, then the computer reboots, services start, the installer updates the registry settings, files are copied again and in the place where needed Enter the username, a black screen appears and does not disappear.

• After 5 minutes of useless waiting, we repeat the installation process during which all existing partitions on the hard drive are deleted (personal files are previously copied to a flash drive) and Windows 7 is installed directly into the unallocated space, but to no avail.
• Recheck the BIOS settings, repeat the installation a third time, Windows 7 won't install not at all. I booted using the Acronis Disk Director boot disk, I look at the hard drive, everything is fine with the partitions, there are no shifts, there are only two partitions. The first suspicion, as usual, falls on the Windows 7 installation disk and drive.

• I go home and bring my seven and my disk drive, change the SATA cables for the hard drive and DVD-ROM, repeat everything again with my disk drive, as well as my Windows 7 installation disk, and to no avail.

• We decide to replace the hard drive for a while, since I always carry a simple 240 GB SATA hard drive with me. We completely format it, repeat the installation process and imagine everything ends in the same place, User Choice.

• We sit and think badly about the motherboard, we suspect the south bridge, it is the one that is involved in data exchange with peripheral devices, in particular with the disk drive. Maybe RAM? By the way, the computer is under warranty and there are stickers on all components that cannot be removed or disassembled. I downloaded Acronis Disk Director again, deleted and created new partitions using it, everything is useless.

We disconnected the system unit and went to the store of my friends from whom we bought the computer, we arrived and said: so they say, so,Windows 7 won't install. They listened to us carefully, took our installation disk with seven and installed the operating system on our computer in 25 minutes and with a grin they pushed the system unit back to us, saying one zero in our favor.We arrived home not at all happy and decided: we will sort it out. Just in case, we made a backup of the installed Windows 7 in the program and hid it away, decisively removed the installed seven and started the installation process again. After some time, in a painfully familiar place, Malevich’s black square appeared. What are your thoughts friends?

• To agree to turn it around and never find out what’s going on, no, I won’t be able to live with that, I won’t sleep.

Why did everything work out in the store? There was another monitor and all the cables, I have everything in my bag, we change the cables and admire the black screen for the tenth time. What about the monitor? Here we have a guess. How come we didn't figure it out earlier? My friend’s system unit is connected to the monitor, but also to the TV via an HDMI cable. The video card has an HDMI output and the TV too, which means that when installed, Windows 7 sees two monitors and two screens and makes the TV the main screen. Then, naturally, you need to look for the image of the continuation of the installation of the seven, no matter how funny it sounds, on TV. We didn’t look for anything, but simply disconnected the HDMI cable from the system unit and repeated the installation of Windows 7 for the eleventh time and that’s it, my dears, the seven was installed without problems, and it was installed before, only you had to select a user name on the TV, which by the way is everything worked this time.After successful installation, we connected the system unit and the TV, then went to the NVidia panel and adjusted the screen resolution, that’s all.

Friends! Read detailed instructions on our website.

Hello dear friends! This weekend I came across a computer on which I needed to install Windows 7. But a problem appeared that I encountered for the first time. When I started the installation of Windows 7, the installation window did not appear (first window, language selection). And then the seven took a very long time to install. If you have the same problem when Windows 7 takes a long time to install, And The installation window does not appear, then now I will write how to solve this. At least I’ll tell you how I solved this problem.

I'll probably start from the beginning. They called me and asked me to come and look at the computer, otherwise: the Internet does not work (Intertelecom there), the antivirus always shows some window, nothing starts, etc. In short, a complete set of all sorts of different breakdowns. And I’ve already dealt with this computer, such a powerful “machine”, new, only Windows XP is installed on it, not that it’s bad, it just surprised me. And when I asked the owners why Windows XP was installed, they said that they installed it in the store. I said that it wouldn’t be a bad idea to set it to seven, after all, it’s newer, and on the same hardware.

I came a second time, turned it on, and there was something incomprehensible there. Perhaps it was a virus that worked this way, or it was children :), but Avast stuck some kind of warning, there were almost no icons on the notification panel, the Internet did not react in any way to an attempt to open a connection, the theme was changed, and it was not possible to return to the standard one. And many more different unpleasant moments.

I looked and decided that it would be easier to demolish everything, format the C and . After explaining everything to the owner of the computer, we decided that we would do just that.

Everything is fine, the computer rebooted and booted from the installation disk. The file loading bar appeared when installing Windows 7, and when the language selection window should appear, nothing happened. The window did not appear, there was only a splash screen (well, the same as when installing seven) and a cursor. I waited about three minutes and restarted the computer. I realized that something was wrong. I decided to go into the BIOS again and look at the settings. Now it’s clear why the store installed Windows XP; most likely, installing Windows 7 failed.

I eliminated the problems with my installation disk immediately, I have installed it more than once. Yes, and I had an exact copy, with which the Windows 7 installation window also did not appear. I didn't see anything strange in the BIOS, and... It did not help, Windows 7 was not installed, the language selection window did not appear. I decided to open the system unit and see how and what is connected there. I didn't see anything interesting there. A hard drive and an optical drive were connected via the SATA interface.

I tried to run the installation again. I launched everything the same, only the background, but there is no window with a choice of language. I decided to wait. About 5 minutes later a window appeared with a choice of language, well, at least it’s something, I thought. I clicked next and the message appeared “Starting installation...”, and that's it. The computer was “thinking”, I understood this from the fact that the cursor was spinning (something was loading), I decided to wait a little.

About 10 minutes later a window appeared in which I selected a clean installation of the system, again waited 5 minutes, formatted the partition for Windows 7 and began copying files. They took longer to copy than they should have, it seemed to me. In short, with grief in half, I installed Windows 7. Then I realized what a long installation of Windows 7 was :).

Slow but established

The computer worked as expected from such hardware, very quickly. All that remains is to configure it. But I didn’t have a driver for the modem, so they decided to take the system unit to me and pick it up the next day.

Finding reasons for slow Windows 7 installation

At home, I set everything up, and decided to torture the computer a little more and find out why it was taking so long to install Windows 7, I was interested. Moreover, I did not find a specific answer to this question on the Internet, only guesses.

Setting up a SATA hard drive in BIOS

To begin with, I opened the system unit and changed the hard drive and drive connections. I connected the hard drive from SATA 0 to SATA 1. And the CD/DVD drive is in SATA 3.

Then I went into the BIOS again. I was interested in the SATA controller settings. Chapter .

Against OnChip SATA Controller the parameter was Enabled. Okay, then we see the item, I have the Native IDE option. This is not very good for a SATA hard drive, as it will not show all its capabilities.

I changed the parameter value to AHCI (the best option for SATA drives). I tried to turn on the computer. The drive was not detected at all, and as soon as Windows 7 started loading, the blue screen flashed and the computer rebooted.

I decided to put RAID in the parameter instead of AHCI (combines disks into an array), nothing worked (I knew it was useless, but decided to try), everything is the same as with AHCI.

Installed it back Native IDE. All these experiments did not help. Although it is very strange why AHCI did not work, I never understood it.

Disable Drive A

I also saw that opposite the Drive A table there was a parameter “1.44MB, 3.5”. This is a disk drive, and this computer does not have one. So I set it to “None” to tell the system that it is missing.

I saved the settings by pressing F10. I installed the installation disk with Windows 7 and tried to run the installation again to check how the seven would install, just as slowly or faster.

And to my surprise, everything worked as expected, a window quickly appeared with a choice of language and so on, I quickly got to formatting the disk. Of course, I didn’t format it, since the computer was already set up and should have been picked up by now.

How to solve the problem of slow installation of Windows 7?

Let's summarize, otherwise I've scribbled a lot of text :). There was a problem with installing Windows 7, it took a very long time to install, and I had to wait a lot until the window with the choice of language appeared, and then “Starting installation...” hung for a long time.. If you have such a problem, then you can just wait and everything will be installed. I have it installed.

If you want to try to solve this problem, then:

1. Try setting AHCI next to the item in the BIOS (most likely it didn’t help me).
2. Change SATA connectors for the hard drive and drive.
3. Disable Drive A (disk drive).

I did the last two steps, and the installation of Windows 7 went quickly. I can’t say with 100% certainty that this is what helped restore the normal installation speed of Windows 7. But in any case, you need to try.

Sorry that there was so much text, I just wanted to describe everything in as much detail as possible. I hope that my experience was useful to you, if you managed to solve this problem, in this or some other way, write about it in the comments, it will be interesting and useful. Good luck friends!

Do you want to install Windows 7 on your computer or laptop, but don’t know how? It's not as difficult as it seems. Although the first time, of course, will be difficult. But, once you figure it out, you will become a real “IT master” and will be able to independently install Windows 7 on any computer or laptop.

Before installing Windows 7, print this page. This will make your task much easier. After all, during the installation of Windows 7 there will be no access to the Internet. The only exception is when you have a second PC, laptop or smartphone, from which you can, if necessary, access the site again and see what to do next.

When is Windows 7 installed?

1. You bought a new laptop or computer. Everything is clear here. In most cases, laptops or PCs either do not have any operating system at all, or do not have the one you need (for example, the ancient MS-DOS).
2. You didn’t like Windows 10 or 8, and you want to install the good old “seven”.
3. There was a malfunction, a virus or ransomware advertising banner was caught, the computer or laptop does not turn on, etc.

Let's dwell a little on the last point. If problems occur with your computer or laptop, do not rush to reinstall Windows. Firstly, reinstalling the operating system is done as a last resort when other methods have not helped.

Secondly, remember that after installing Windows, all data is erased, at least on local drive C. And these are all your programs: browsers, video players. And you will have to install everything again.

Thirdly, there are no guarantees that reinstalling Windows will help solve the problem. But the files on local drive C will be deleted permanently in any case.

Therefore, first, try to look for other solutions to restore your PC or laptop. For example, the following articles may help you:

You can also always look for other articles on this blog or through Google/Yandex.

Preparing to install Windows 7 OS

The first thing you need to do before installing Windows 7 on your laptop is to copy all important information. At least from local drive C. After formatting, all data on it will be erased.

If you bought a new computer or laptop, you can skip this step. In all other cases, this is a prerequisite!

Therefore, save all files, documents, pictures, audio tracks and videos from your desktop and from the “My Documents” folder. It is also recommended to look at the local drive C - important information is also written to it quite often. Where to save? On a disk or flash drive. Another option is to upload files to online services (Yandex.Disk, Google Drive, etc.).

By the way, sometimes you can copy some programs along with the settings. For example, bookmarks and passwords from the browser you used.

The second point that needs to be made is to determine what bitness of Windows 7 you need - x86 or x64. Everything is very simple here. If you have 4 GB of RAM (or more) installed on your laptop or computer, then you need to install Windows 7 x64, and if less, then x86.

Why is that? The fact is that the x86 version does not see 4 GB of RAM. The maximum that it shows is 3.25 GB.

How to find out the amount of RAM? If you have a new computer, look in the documentation. And if it’s a laptop, then the characteristics are indicated on its case (or on the box).

If you already have Windows installed, then the amount of RAM can be viewed as follows:

The third thing that needs to be done before installation is to burn a digital copy of Windows 7 to a disk or flash drive.

If you already have a boot disk (bought or given in a store along with your PC), then skip this step.

Burning a DVD is easy. After all, you've probably already recorded films, music, games? This can be done through Nero, Alcohol 120% and other programs.

As for the USB flash drive, there are some difficulties. Therefore, in this case, I recommend reading -.

Where can I get a Windows 7 image or installation disk? Can be purchased in store or online.

And the last thing you need to do before installing Windows 7 is to prepare drivers for your laptop or PC. Driver discs are usually included with your computer. If you have them, then you can skip this point.

Laptop owners are not provided with disks, so you need to install drivers from the manufacturer’s official website (search by the name of your model).

If you skip this step, you may be left without internet. After all, you need to install a driver for it. USB ports may also not work. That is, a mouse. And in the end you will have to go to a friend or acquaintances and download the drivers from them.

This completes the preparatory process. Check again that you have saved all the important data, then connect a USB flash drive or insert a DVD with the Windows 7 installation image and restart your laptop/computer.

Setting up BIOS for installing Windows 7

Perhaps setting up the BIOS is the most difficult stage for most users. Especially for beginners.

In addition, the difficulty here is that the BIOS versions may differ on different PCs and laptops. And the buttons to enter the BIOS too. As a result, some users cannot even enter the BIOS. Therefore, to avoid problems with this, let’s consider in detail what needs to be done and how.

So, when you have prepared everything, restart the computer, and immediately when the screen turns on, repeatedly press the Del button (for PCs) or F2 (for laptops). If you did everything correctly, you will see the BIOS screen. Something like this:

Or this:

There are 4 devices displayed here - First Boot Device (first), Second (second), etc. By default, the first one is the hard disk (Hard Disk or HDD). And you need to put the CD-ROM (disk) or USB-HDD (flash drive) on the first line - depending on which device the seven will be installed from.

How to do it? On a PC, you usually need to highlight the first item, press Enter and select the desired option from the drop-down list.

On laptops, the device boot priority can be changed using the arrows or F5-F6 buttons. Control keys are usually located on the right or at the very bottom of the BIOS screen.

When you select the desired device (CD-ROM or USB-HDD) in the first item First Boot Device, be sure to save the settings and then exit the BIOS. Which save button? This is also written at the bottom of the screen (usually F10).

If you have a BIOS UEFI (new version), then simply drag the desired icon (disk drive or flash drive) to the first place with the mouse and click “Exit” in the upper right corner.

After this, the laptop or computer will reboot and the installation of Windows 7 will begin.

If all this is too complicated for you, there is another option to configure booting from a disk or flash drive without going into the BIOS. For this you can. But this method only works on new PCs and laptops.

Step-by-step instructions for installing Windows 7

Immediately after rebooting, you will see a black screen with a single line.

Here you need to press any button - for example, Space.

If this message does not appear, it means that you did not save the BIOS settings. Check them again. If everything is fine there, then either you did not write the bootable USB flash drive correctly, or the disk is damaged and the computer/laptop does not see it (the disk drive may not be working).

After clicking the button, you will see a black screen with the inscription “Windows is downloading files...”.

Wait for the system to copy everything. After this, a new window will appear on the screen. Select Russian language and click “Next”.

In the new window, click the “Install” button.

If there are several versions of Windows 7 recorded on a disk or flash drive, you need to choose the appropriate one. We have already figured out the x86 and x64 bit depth, so decide for yourself here. As for the version, it is better to choose “Maximum”. Although there is almost no difference between it, “Home”, “Beginner” and “Professional”, so this is not so important. Select the desired item and click “Next”.

Agree to the license terms (check the box) and proceed further.

Choose the full installation.

A window will open asking you to select a partition for installing Windows 7. But here it’s worth going into more detail.

How to partition a disk during first installation?

If the installation is performed on a new computer or laptop (i.e. for the first time), then you will see only one line - “Unallocated disk space”.

And in this case, you need to split the hard drive into 2 partitions - local drive C and D (more is possible, but this is not necessary). To do this, select this line, click the “Create” button, indicate the disk size (in megabytes) and click the “Apply” button.

Don't know how much 50 GB is in megabytes? Write a number at random - for example, 50000. And then see what volume the system will show for the created partition. If it turns out too little, select it, click the “Delete” button, and try again, specifying a larger number.

For Windows 7 to work properly, you need to create a special partition with a capacity of 100 MB where boot files will be stored. So when the next window pops up, just click OK.

When you specify the required volume for local drive C and create it, “Partition 2” will appear. This is him.

After that, select the “Unallocated space” line again, click “Create”, and then the “Apply” button. After this, local disk D (“Partition 3”) will appear.

If you forget to do this, then after installing Windows 7 there will be only one local drive C. And partition D will “evaporate” into thin air. You'll have to reinstall Windows again. Therefore, before moving on, make sure that the “Unallocated Space” option is no longer there.

To install Windows on local drive C, select “Partition 2” and click “Next”.

If you reinstall Windows 7, then the following window will appear on the screen:

In this case, you need to select “Section 2” and click the “Format” button. This will delete all data on it. When the formatting process is complete, select this section again and click “Next”.

By the way, if you want to distribute the volume differently between local drive C and D, you can delete them and create them again, specifying a different size. How to do this is written in the previous paragraph. But remember: in this case, the information will be deleted on the local drive D too! As a result, your PC or laptop will be clean, as if you had just bought it. Therefore, perform this procedure only if you have saved all the necessary files.

Continue installing Windows 7

So, you were able to partition your hard drive or format it before installing Windows 7 and clicked the “Next” button. After this, the operating system will begin to install. Wait until the files are copied.

After this, the computer/laptop will reboot and you will again see the familiar black window with a single line.

Under no circumstances press anything on the keyboard, otherwise everything will start all over again.

After this, the computer or laptop will reboot a second time.

Well, the main thing is already behind us, all that remains is to fill in some fields:

1. Indicate the username and computer name (if you plan to play games, it is better to write in Latin).
   
2. You don’t have to set a password - in that case, just move on.
   
3. If you have a digital copy, you also don’t have to specify the activation key (usually Windows 7 is activated automatically when you connect to the Internet). To skip this step, click Next. And if you bought a disc, then enter here the code that is written on the sticker.
   
4. Here it is recommended to select the “Delay decision” option (you can change these settings later).
   
5. Select your time zone, specify the time and click “Next”.
   
6. If Windows automatically finds drivers for the Internet, then in the new window select “Home Network”.
7. Wait while the desktop setup is completed.
   
8. Congratulations – you have just been able to install Windows 7 on your laptop or computer yourself.
   

What to do after installing Windows 7?

First of all, reboot your laptop or computer, go into the BIOS and change the device boot priority back. That is, put the hard drive (Hard Disk or HDD) in first place, and lower the CD-ROM or USB-HDD to second or lower.

Also, after installing Windows 7, the Internet and USB connectors may not work. This is because there are no drivers. Therefore, at the next stage you install them.

This is precisely why you need to prepare all the necessary drivers in advance before installing Windows 7. Especially for the Internet. After all, how will you download them if you don’t have access to the network?

And one more nuance - when you turn on your computer or laptop, you may see two Windows 7 (during boot).

The first one was installed by you, and the second one was saved in a hidden section (“reserved by the system”). However, the extra line can be deleted. To do this, do the following:

Ready. After the reboot, the second Windows 7 will no longer exist, and you will not see the operating system selection menu.

If you have any questions, ask them in the comments.

When installing an operating system, a fairly large number of problematic situations may arise. Let's look at the most common errors that lead to the phrase “I can’t install Windows 7.”

• "The system cannot be installed due to a read error." This type of problem is typical when the installer boot disk is damaged or when there are errors accessing the hard drive of your computer.
  To resolve the problem, use a different installation media and check your hard drive for errors using various boot utilities. To check the quality of the boot disk, you can try installation on another computer. It is worth noting that this error occurs in most cases when using a pirated copy of the OS or custom “assemblies”. All these modifications are almost always associated with the removal of certain information from the installation image, which leads to a violation of the integrity of the file.
• "Format could not be completed." Windows 7 does not install when you try to perform operating system actions on the disk in Windows operating mode. Existing installation media allow you to perform various operations with the hard drive while the operating system is running, but in some cases a system failure may occur when the installer tries to gain access to the HDD sector. The solution is to use the bootable version of the installation disk and perform the formatting operation from under it.
  
• "The installation could not complete successfully. Device driver not found." This problem arose with the widespread use of the SATA interface. The cause of the error is the BIOS setting, which is responsible for the type of device being connected. For proper operation of the system and completion of the installation process, you must set the SATA Mode parameter to ACHI. After this, you need to start the installation process again. The second reason for the error may be the use of devices with unsupported drivers in the computer configuration. This can be as simple as using an outdated model of hard drive or (more often) connecting new devices to the motherboard with outdated BIOS drivers. To solve the problem, you need to visit the motherboard manufacturer's website to update the drivers. If this update does not exist, you will have to stop using this equipment.
• "The installation process completed with an unknown error." This message is often the most difficult to determine the source of the error. According to the analysis, the error occurs due to a malfunction of the computer components. In this case, the failure can be either systematic or one-time.
  To solve the problem and successfully complete the installation process, we recommend performing the following algorithm.
  1. Turn off the computer's power and check that the components are installed correctly. Often the message appears due to loose contact of the RAM sticks with the connectors or a hard drive interface cable not being connected all the way. When these devices operate, a discharge may occur that blocks operation.
  2. Check the functionality of the hard drive with utilities. When a hard drive fails, the boot sectors are the first to stop working correctly. When the operating system is running, this may not be noticed for a long time, but the installation activates them.
  3. Use bootable media with a different version of the service pack or operating system version. If the characteristics are not suitable for installation, an abnormal termination will occur.
  4. Check the temperature of the devices. The installation process activates almost all devices on the computer. If thermal regulation is poor, the processor or hard drive may overheat and cause emergency failures in their operation.

If after performing all the above steps the error does not disappear, then there is a high probability of a breakdown and you will have to contact service centers to fix it.
