Why does Windows give an error when reinstalling? Problems with Windows Check with the sfc scannow command

Facebook

Many users, when serious problems occur in Windows XP, prefer “amputation”: formatting the disk and completely reinstalling the OS. However, such a simple and radical surgical method is not suitable if the system has many important programs installed and configured, the reinstallation of which is impossible or would be too expensive. In this case, an in-depth diagnostic of Windows is required.

Each type of Windows XP failure has its own cause, and therefore, although there are quite clear recipes for getting rid of the most common problems, it is impossible to develop any universal “treatment” method to eliminate most “glitches”. The configuration of each operating system, software, drivers and hardware is unique, and most often it is possible to find out the cause of the problem only by carefully dissecting the hardware and software inside of a particular computer. If the failure does not accompany the OS right from the moment of its installation, but appeared at some specific moment (after installing another program or driver, changing Windows settings, power failure), then it is easy to get rid of it, just remove the problematic application, or restore the registry or even the entire contents of the hard drive from a backup. Not only the standard System Restore will help with this, but also more interesting programs, for example, Norton Ghost, Ashampoo Uninstaller, WinRescue XP. Of course, this is possible if the user does not disdain prevention and regularly uses such programs, which is not at all difficult, by the way. For example, a full backup of a 10 GB system NTFS partition in Norton Ghost takes only 10 minutes (it is unreasonable to allocate the entire disk space to the OS).

If it is not possible to either restore the system with little effort or completely reinstall it, then you will have to look for the cause of the failure yourself. To achieve success in such a thankless and tedious task, it is recommended to follow the following technology:

Preliminary stage

Before starting diagnostics, make a backup copy of the registry, configuration files, or the entire system, so as not to get even bigger problems as a result of experiments. Be sure to remember all your further actions so that in case of problems you can easily cancel them.
Delete all temporary files, clear the browser cache, Recycle Bin, Journal, empty the Program Files\ Internet Explorer\ Plugins folder with IE plugins (make backup copies to restore them). Clear the folders from which MS-Office scripts autorun (such as Documents and Settings\ USER\ Application Data\ Microsoft\ Excel\ Xlstart, Documents and Settings\ USER\ Application Data\ Microsoft\ Word\ Startup), delete the normal.dot template, used by MS-Office. Empty the Windows folders\ Downloaded Program Files, Documents and Settings\ USER\ NetHood, Documents and Settings\ USER\ PrintHood, Documents and Settings\ USER\ Recent. Remove autorun.inf files from all local drives.
Check the system with several recent antiviruses and the Ad-Aware program, scan the hard drive with utilities such as ScanDisk, Norton DiskDoctor (with the mandatory inclusion of write testing). Check system files using the System File Checker utility (SFC /SCANNOW command) and restore damaged libraries from the Windows distribution or Service Pack.
Update the system: in addition to the latest service pack (if it is already installed, reinstall it) install all the latest patches on the Windows Update website (windowsupdate.microsoft.com, just keep in mind that some patches themselves can be a source of problems). Update (reinstall) Internet Explorer and the JAVA virtual machine from Microsoft. Update DirectX using the redist distribution (about 25-30 megabytes in size, and the file name contains the word “REDIST”: DX90b_Redist.exe). Sometimes it is useful to first remove Internet Explorer or DirectX, and then install it again - for this you can use the XPLite utility.

Search for a ready-made solution

Carefully study the documentation for the faulty program or expansion card; perhaps it contains some special instructions. Also visit the website of the developer of the faulty program or device - perhaps the manufacturer's technical support service knows about the problem and offers to download a patch.
If the failure is accompanied by error messages (for example, STOP errors on a blue screen), then write down their exact contents and go to the Microsoft support site. Based on the error message, you need to formulate a query for the search engine (for maximum search efficiency, try formulating the query in several different ways). Finding a solution in the Microsoft database is the fastest way to resolve the problem. If there is no information about your failure in the Microsoft database, then run a specialized Internet search utility, for example, Copernic or Search Plus, and also try to find materials on similar problems on the Internet and in UseNet technical conferences. Or use Russian and foreign search engines such as Yandex, Yahoo or Google.
Just keep in mind that if your system has automatic reboot mode enabled in case of failures, the “blue screen of death” message will not be displayed. Therefore, in the Control Panel - System - Startup and Recovery - Settings menu, uncheck the Automatically restart flag in advance.
To obtain maximum information about the failure that occurred, also refer to the system error log - Event Log (Computer Management - Event Viewer, “Computer Management” - “Event Viewer”). Documentation for most Event ID event codes is available on the Microsoft Events and Errors Message Center and www.eventid.net websites. Something can be squeezed out of the Dr.Watson system debugger, which can be called from the System Information program window.
In Windows XP, enable error reporting mode to Microsoft: Control Panel → System → Advanced → Error reporting → Enable Error Reporting (Control Panel → System → Advanced → Error Report → Enable Error Reporting). You will laugh, but there have been cases when, after sending information about a failure to the developers, the user received a response with a specific solution to the problem.
Check out sites dedicated to the nation's efforts to combat Windows crashes, such as www.techadvice.com, www.jsiinc.com/reghack.htm, www.mdgx.com, www.aumha.org, labmice.techtarget.com/troubleshooting/generalguides .htm - on them you will find links to articles devoted to troubleshooting many common failures.
Visit popular web and UseNet conferences on operating systems, software and computer hardware. Having formulated a description of the failure of your system in extreme detail (and not forgetting to indicate its version!), indicating the exact content of the error message and describing the configuration of your system, try asking for help from other users - perhaps someone has already encountered a similar problem and knows its solution, or may suggest the direction of further searches.

Checking settings

In the Control Panel, check all system and hardware settings - set all parameters to the “Default” position. Specifically, remove page file size limits, check that you have enough disk space, and temporarily set your environment variable settings to a shorter path to the TEMP folder (for example, C:\TEMP). Even in your keyboard settings, set the default language to English. Also check all settings in the options of the applications you use.
Return the settings in the registry and in the configuration files user.ini, system.ini made using tweaking utilities to their original state. Check the settings in the files autoexec.nt, config.nt, _default.pif. Run a search in the registry for the word “Policies” and delete all parameters in the found sections (except for the PowerCfg sections responsible for power policies, as well as the HKEY_LOCAL_MACHINE\ SOFTWARE\ Microsoft\ Windows\ CurrentVersion\ Internet Settings\ TemplatePolicies section, which contains IE security policy templates) - Perhaps the failure is just a consequence of restricting user rights. Carefully check your current security policy settings in the Group Policy Editor (GPEDIT.MSC).
Return the settings in the BIOS to the original - Default - state, experiment with different CMOS Setup options, for example, disable DMA mode for disks, change memory timings, disable all integrated devices, enable the “hole” in the region of 15 megabytes of memory. Disable everything related to power management in CMOS Setup, including ACPI. Or vice versa - enable all these options if they are disabled. Similarly, experiment with the PnP OS Installed and USB Legacy Support option. Update your BIOS. And give up overclocking: overclocking is the main enemy of Windows XP!

System and programs

Run the msconfig.exe utility and disable all startup programs. Try also experimenting with the Selective Startup mode - perhaps the incorrect entry is hidden in system.ini or win.ini, another rudimentary configuration file. Using msconfig, it is convenient to check system services, for example, by comparing the list of running services with another PC on which a similar failure is not observed. A good description of the purpose of Windows XP services, which will help you find out the initial and recommended status of their configuration in different versions of Windows, can be found at www.blackviper.com. Try disabling unnecessary services, for example, WEB Client, and also check service dependencies using the Services snap-in.
Try to remember after what actions the failure appeared. Uninstall several programs and drivers that were most recently installed - perhaps one of them is causing the system to crash or conflicts with other programs and hardware, causing them to crash. Uninstall any programs that were created more than two years ago and have not been updated since then. Remove antiviruses and other software that closely integrates with the system. Be sure to use a specialized uninstaller like Ashampoo Uninstaller, both when installing and uninstalling programs - this is the only way to completely clear the system of all traces of the program or driver being removed! In addition, analysis of the uninstaller log allows you to find out which files on the disk and which parameters in the registry were changed during the installation of the program - often to eliminate the failure it is enough to change the incorrectly changed parameter in the registry. When reinstalling programs and drivers, try not only the latest version (note that some programs are regularly updated with patches), but also the older one - it often turns out to be more stable. Try reinstalling the failed application in a different directory with a shorter name.
For outdated programs, try installing a special compatibility mode. To do this, create a shortcut to the program, go to its properties and on the “Compatibility” tab, in the “Run in emulation mode” item, select the compatibility mode with another type of Windows. In addition, use the Application Compatibility Toolkit, which is designed to significantly expand the capabilities and manual configuration of this mode.
Try running the failed application under an administrator account. If the program runs only under it, then from the Administrator account, find the section with the settings of the desired program in the HKEY_LOCAL_MACHINE\ SOFTWARE registry branch and right-click on it. Select the “Permissions” command from the menu that appears and set full access to this registry branch for the user or group of users who are allowed to work with it. Also find in the HKEY_CURRENT_USER branch the section corresponding to the faulty program and export it to a REG file. Now log in as a regular user and import this REG file back into the registry. Sometimes you can get rid of such a failure by deleting your account (and your entire user profile) and then creating it again.
Try finding and fixing errors in the registry using a program like Norton WinDoctor. Errors found should be corrected only manually, analyzing each of them. To do this, you need to try to find out which program or system setting the erroneous registry entry relates to by looking in RegEdit at the branch that WinDoctor signals - using the names of files, parameters, or the specified paths, it is easy to install the application that generated the error. Try using other diagnostic utilities, for example, the DirectX Diagnostic Tool included in Windows; it will check DirectX files, drivers, and settings of some devices. Some simple glitches can be fixed by the Tweak UI program; it has a “Repair” tab for this purpose.
Some Windows XP problems can be resolved by restoring the hard disk's master boot record (MBR) using the "fdisk /mbr" command after starting the PC from a Windows 98 floppy disk (this is necessary to subsequently overwrite the disk ID), or by using the recovery console commands "fixboot" and "fixmbr" " Boot your PC from a Windows 98/Me NTFS-enabled floppy disk (use NTFS for DOS Pro to do this) or ERD Commander disk and delete the PAGEFILE.SYS file. ERD Commander, generally speaking, is an excellent program that is a kind of LiveCD for Windows XP. It allows you to fix many problems and access OS settings, even if Windows itself does not boot into crash protection mode. Check for errors in boot.ini and current access rights to files and folders: the “System” and “Administrators” user group must have full access rights to the root directory of the system drive and to the virtual memory file PAGEFILE.SYS.
Monitor various system events, queries and registry accesses at the moment of a failure using special monitoring programs. By analyzing access to the registry, you can, for example, determine which parameters from the registry are requested by the program immediately at the time of a failure - perhaps some of them are missing or have an incorrect value. And by analyzing access to files, it is easy to understand which files contain the settings of the faulty program, and which files it needs are missing. Utilities from SysInternals will help with this: Registry Monitor - analysis of accesses to the registry, File Monitor - monitoring of access to files, DllView - information about libraries used by current processes, OpenList - information about all open files, PortMon - access to ports, TCPView - information about connections via the TCP protocol. The TaskInfo program is best at displaying information about all running programs. It will also show how much CPU resources each application consumes. You can find out the cause of the jam that occurs during boot using the well-known diagnostic utility BootVis (however, Microsoft no longer distributes it, so use the search). Also check the system with a comprehensive diagnostic and information package SiSoft Sandra or AIDA32.
Remove unnecessary fonts, disable all performance counters, make sure that there are no folders or files on the disk with very long names or extensions (220 characters or more), do not use very long command line parameters (220 characters or more) when working with programs.

Equipment

Update all drivers for all devices (or remove and reinstall the drivers of the problematic device, as well as the driver of the device to which it is connected), especially the chipset drivers: Intel Chipset Software Installation Utility and Intel Application Accelerator or VIA-4-in-1 ( plus other drivers and patches from VIA, such as VIA IRQ Routing Miniport Driver, VIA IDE Miniport driver and others, depending on the system configuration). Check for special patches and updates on the websites of equipment manufacturers, and most importantly, the motherboard.
Check the serviceability of the equipment, the correct installation of jumpers on it, test it using utilities such as Memory Test, CPU Stability Test and the like. Check everything, right down to the battery, power supply voltage and the quality of the motherboard fastening - there should be no spontaneous short circuits or unreliable contacts anywhere!
Temporarily replace all memory modules - this is the device that fails most often. If this is not possible, then try limiting its size, for example, to the first 64 megabytes. In Windows XP, it is convenient to use the MSCONFIG.EXE utility for this: the MAXMEM parameter in the boot.ini file. Try a more powerful power supply, oddly enough, lack of power is very often the cause of Windows crashes.
Check the temperature and functionality of the cooling devices of all system components, even the chipset (you can even install a special fan on the chipset heatsink). Ground the PC, install a surge protector or an uninterruptible power supply. Check the quality of the telephone cable, network cable, electrical wiring.
Remove all additional devices from the PC (except the hard drive and video card, although sometimes replacing the video card helps), even the internal tweeter, and then in crash protection mode, using the “System Properties” dialog, remove them drivers and see if the problem is gone. If it disappears, then install the devices back one by one, each time repeating the procedure, which usually leads to an error message - perhaps there is some kind of hardware conflict and in this way you will either identify its source, or the system will re-allocate resources and eliminate it itself .
Install the problematic device in another PCI slot, in the system properties and the System Information utility (Program Files\ Common Files\ Microsoft Shared\ MSInfo\ msinfo32.exe) check for no conflicts. The SiSoftware Sandra program is very good for obtaining information about the system. If ACPI is disabled, try manually reassigning conflicting interrupts (or other resources, such as DMA channels or I/O ranges). Try replacing the problematic device with exactly the same one, or with a device of a different brand - perhaps a defective unit is simply to blame, or changing the manufacturer of the expansion board will eliminate the conflict. For disks, try a different cable, instead of an 80-wire cable, try a 40-wire cable and vice versa, check that the Master/Slave jumpers are set correctly, move the disk to another cable, set it in CMOS Setup to either auto-detection mode, or set its parameters explicitly, or set it to "NONE". Do not connect other devices to the same cable with the problem disk.
Look at the properties of the problematic device - perhaps there are settings there that will resolve the problem, for example, disable or enable DMA mode for the disk. If the computer does not boot, try accessing these menus from Safe Mode.
In case of problems with drivers, boot the PC in crash protection mode, in Device Manager, remove the problematic device (as well as all printers and devices that do not exist in reality, even joysticks) and after loading the OS in normal mode, install the latest driver. However, sometimes an older driver turns out to be more stable, try different versions. Please note that instead of rebooting, a failure can sometimes be resolved by completely turning off the PC and then turning it on after a few minutes of idle power. If the failure has something to do with the network, then in the Network properties, remove all network components and after rebooting, install everything necessary again. Remove all printers if there are problems with them, and also reinstall their drivers after rebooting. Remove all drivers that are not certified for Windows XP; the File Signature Verification utility, called from the System Information program window, will help you check the signatures of system files. If the driver was installed unsuccessfully, then use either loading the last known good configuration (called in the Windows boot menu), or roll back to the previous version of the driver in the system properties.

It's bad

Reinstalling Windows over a previous installation will restore all files to their original versions, but will retain the main settings in the registry, so if the cause of the failure is incorrect registry settings, then such a reinstallation may not fix anything. In some cases, immediately before installation, you can remove all hardware from the crash protection mode in the “System Properties” dialog so that Windows can reinstall all the drivers. Also try different OS distribution disks - the original disk may be damaged.
After completely erasing the Windows, Program Files, System Volume Information and Recycler folders (or repartitioning and formatting the disk), install Windows bare-bones. Perhaps Windows 2000 or Windows 98 will be more efficient. Sometimes you need to format the disk with a special utility from the hard drive manufacturer to completely reset it. In some cases, for example, after programs like Partition Magic work incorrectly, to fix the failure you need to partition the disk again using standard Fdisk.

Found problems with Windows? Today we will tell you how to identify operating system problems and how to start the OS after updating.

from 120 rub. RUB

When using a personal computer for a long period of time, it is impossible to avoid any problems. Sometimes the equipment itself fails, while in other cases the reasons for incorrect operation are related to the operating system itself.

The most common Windows OS problems (Windows)

Activation errors.

In most cases, such a Windows malfunction occurs as a result of updating from the seventh or eighth version to the tenth. An incorrectly performed procedure leads to OS activation failures.

To get rid of a problem with Windows like this, first of all, you should open the start menu, where you select the “Settings” column, then click on the “Update and Security” item, and then proceed to direct activation. Here you need to select the “Go to store” field and see if a valid license is freely available. If it turns out that it is not available, then you need to purchase a new one in the Store.

Also, a similar error occurs if the computer does not have access to the Internet or the firewall settings do not allow the system to complete the activation process via the network.

Chrome browser not working correctly.

Problems with Windows caused by any malfunctions in the operation of this Internet browser also in most cases occur with the tenth version of the system. Among such problems, we should highlight slow performance, especially when performing fairly resource-intensive tasks, as well as watching videos. Some users were able to solve this problem by reinstalling Chrome.

Folder problem.

Many users have reported a problem with Windows such as the mail client not working properly. In the new operating system, the program does not allow you to create special subfolders in order to optimally organize mail correspondence.

Unstable Wi-Fi operation.

If the Windows problem you are encountering is caused by a problem with your wireless network, then the simplest thing you can do to fix the problem is rebooting your PC. But a greater effect can be achieved by disabling the wireless network sharing function, which is active on the system by default. In some cases, by disabling this option in the Wi-Fi settings, it is possible to increase the stability of such a connection.

Windows problems caused by driver problems.

As a rule, this problem is observed on devices with Nvidia video cards, as well as multiple monitors.

To solve this problem, you need to roll back to the previous version of the driver.

The operating system does not start.

The most common error is Disk Boot Failure, which occurs immediately after turning on the computer. In this case, instead of the usual system boot, a message about this failure appears.

Problems with Windows like this are due to the fact that the operating system cannot recognize the drive from which you tried to start. This can happen for a variety of reasons. For example, a drive was simply inserted into the device, and the BIOS settings, in turn, are such that the disk or flash drive begins to be used to start the system.

Problem when Windows takes a long time to load

If the system does not start for a long time, then it is imperative to disconnect all third-party devices from the system unit and only after that you can try to turn on the PC.

Also, among the problems that arise due to the BIOS, it is necessary to highlight its incorrect configuration, namely, an incorrectly set boot sequence. It is worth emphasizing that such failures can occur at any time, which means that you need to constantly monitor the battery charge on the motherboard in order to prevent such a problem with starting the system.

Windows 7 is the most popular operating system for home and office computers. There are few users who have not reinstalled this operating system themselves. But some of them encountered a problem: when installing Windows 7, it gives an error, despite accurately following the instructions given on the Internet. Why does this happen? Let's try to understand the main problems that arise when reinstalling Windows 7 and methods for solving them.

Reasons for error messages

It's not just beginners who have problems installing the operating system. So, if you encounter an error when reinstalling Windows, don’t despair - there’s nothing to worry about. Perhaps some points were not taken into account at the preparatory stage. If you get an error when installing Windows 7, it can be classified into one of the following categories:

Problem copying installation files.
Outdated BIOS firmware.
Problems with the hard drive (bad sectors, lack of space).
Lack of drivers for one of the key hardware components (this happens with outdated disk drives and hard drives).

Problem solving methods

Let's look at why errors occur and find out the reasons for the appearance of certain messages.

Problem copying files

This is symbolized by error code 0x80070570. It happens that while copying installation files, the Windows 7 installation process stops with a message about the file being missing or damaged. There are several reasons for the problem:

damaged Windows 7 distribution media;
problems with the file system or memory chips of the flash drive (damaged CD);
the image was downloaded with an error;
The checksum of one of the system files in the image is incorrect.

If, when using the capabilities of torrent clients, the probability of downloading an image whose checksum does not match the original value is insignificant, then it is not at all difficult to become a victim of poor-quality assembly. Here we check the hash of the iso image (using the HashTab or Total Commander utility) and compare it with what is on the source (for example, a tracker).

If everything is in order, then we record the image again, having first fully formatted the media. Full formatting will allow you to check the memory cells of a flash drive for problems. A faulty cell could have caused the problem - it contained a fragment of a file that Windows could not process during installation.

Outdated BIOS

When turning on the PC, go to the BIOS setup menu and check its version and the date of the last update or release. If it has not been updated or was updated in the early 2000s, feel free to go to the developer or motherboard support website and download the latest BIOS version. You may have to look for firmware for the old BIOS in archived websites or on forums. You can read how to update the BIOS in the instruction manual for your motherboard. But the best solution in this case would be to replace the motherboard with a more modern one.

Problems with HDD

There are a lot of problems and options for solving them. First of all, make sure that there is enough free space on the system partition to install Windows 7. If you receive errors about the impossibility of installing Windows 7 on the selected partition, format it using the installer.

To do this, select the volume and click on the “Format” button.

Drive driver missing

If you are using an older CD drive, there may be a problem with the CD drive driver. The fact is that Microsoft did not add outdated hardware to the Windows 7 distribution in order to save the size of the distribution and the very low popularity of old hardware (and few people try to install Windows 7 on old PCs).

Download the driver from the support site and copy it to the USB flash drive. After that, specify the path to the file by clicking on the browse button.

A similar situation occurs when using the USB3.0 socket during Windows installation. Here it’s easier to reconnect the flash drive into the old connector with a USB2.0 interface.

I can't install Windows 7! Inexperienced users often encounter this problem and go to the Internet in search of a solution.

And rightly so, because our material will really help you get rid of a number of possible problems.

To make it easier to determine the “culprit” of installation problems, we will group these objects into several general categories:

installation image – OS installation files;
installation image media – CD, DVD or USB FLASH disk;
image carrier reader;
BIOS of the computer on which the OS is installed;
computer hard drive;
computer equipment;
computer peripheral devices.

When an error occurs, you need to check the groups one by one, narrowing the search for the faulty category, the cause of the fault, and how to solve the problem.

Nowadays, reinstalling the operating system is more often done using a USB FLASH than from a DVD.

This installation requires preparation of both the media and special BOIS settings on the computer.

Preparing a flash drive involves deploying a bootable installation image on it. The following programs are useful for this: UltraISO, WinSetupFromUSB, etc.

Often errors when installing from a flash drive are associated with incorrect deployment of the image.

Case 1. If you can’t install Windows 7 from a flash drive

We check the functionality of the flash drive - connect it to a working computer, try to copy and write several files. We check the disk using standard means (right-click – Properties – Tools – Run check);
We try to boot the computer from a flash drive by inserting it into the rear connectors. There are long wires stretching from the front USB connectors, which can cause interference that distorts the data read from the media.
A telltale sign of a problem is that the installation is interrupted by an error at an unpredictable point during the process.
we check whether . Having connected the flash drive to the computer, we enter the interface. Its name should appear among other hard drives.
If this does not happen, then you need to use another flash drive. The flash drive is detected normally, then we try to prepare it with other programs, use other installation images.

Case 2. If you can’t install Windows 7 via BIOS

In this case, we proceed in the same sequence as in case of problems with a flash drive: is the media working, is the reading device working correctly, is the image deployed on the media working.

If the problem is due to the fact that you cannot get into the BIOS settings window, then we try to set the boot device when turning on the computer using the function keys.

As a rule, the “Boot device selection” function is activated by the F8, F11, F12 or ESC button, via the selection menu.

It is important not to miss the moment and press the button immediately after turning on the computer.

This function can also be used to check whether the USB flash drive is detected by the system.

Case 3. If you can’t install Windows 7, the driver was not found

The probable cause is a hard drive or media that is not supported by standard means. The problem has become especially relevant with the spread of USB 3.0.

The Windows 7 distribution does not support USB 3.0 by default.

Therefore, you need to stock up on drivers or use a non-original image for installation, in which these are already present.

You can find and download a suitable image by searching for “Windows 7 USB 3.0”. When this error is detected, the system provides the opportunity to install the necessary drivers.

Important! If the installation was performed from a flash drive, then you need to move the flash drive from the USB 3.0 connector (blue core) to USB 2.0 (black core) or disable USB 3.0 support through the BIOS interface.

If the flash drive from which you are installing the operating system is in USB 3.0 format, then you need to disable the USB XHCI Controller option in the BIOS, and enable AHCI mode for hard drives.

Another reason for the missing driver error is an outdated BIOS version.

Updating the BIOS program helps overcome the problem. The problem is that the outdated BIOS does not contain instructions for working with large media.

This means that you need a shortened (stripped down) installation image and media with a small amount of memory.

There are cases when a driver search error was associated with minor mechanical damage to the optical media - a DVD disc.

The problem can be solved by recording the installation image onto a working medium.

A drive with a dead laser does not read all disks and may make a reading error in a critical block of installation data.

After upgrading your computer hardware, sometimes the system installation fails due to insufficient power from the power supply.

The problem manifests itself in spontaneous system reboots during installation or prolonged irreversible freezes.

The widely and infamous Blue Screen of Death will invariably occur when attempting to install Windows if there are corrupt cells in the computer's RAM.

The only way to solve the problem is to replace the faulty RAM module.

Peripheral devices attached to the computer may affect installation in unexpected ways.

Therefore, before starting the installation, you need to disconnect everything except the mouse and keyboard.

Installing Windows 7 from a USB flash drive on a computer and laptop

I can’t install windows 7: how to solve basic errors

Reasons for error messages

Problem copying installation files.
Outdated BIOS firmware.
Problems with the hard drive (bad sectors, lack of space).
Lack of drivers for one of the key hardware components (this happens with outdated disk drives and hard drives).
