Why does Windows 7 give me an error when installing? Windows won't install

Hello friends! I haven’t written articles on troubleshooting errors, etc. for a long time. But today they brought me a laptop and asked me to look at it. As usual, they said that the program does not start :). I turn it on, but Windows doesn’t even load, an error immediately appears 0xc00000f on a black screen. And with the text “Windows could not start...”

Details: “The boot menu failed because the required device was not found.”

I had never encountered such an error before, so I immediately went to Google. I didn’t find anything useful, someone immediately advised reinstalling Windows, someone wrote that the problem was solved only by replacing the hard drive, etc. To be honest, I also immediately thought of trying to reinstall Windows, but I was too lazy to set everything up later :) and I decided to try to remove error 0xc00000f without reinstalling the OS.

Without delving into complex and incomprehensible terms, I will say that error 0xc00000f appears due to damage to some system files and the registry. This error may also appear if there are technical problems with the hard drive. In this case, you won’t be able to fix it, but it’s worth a try.

Error 0xc00000f when starting Windows

The first thing I decided to do was launch “Startup recovery” from the installation disk. I booted from the disk, selected the OS to restore and waited. I waited a little and saw that the utility could not restore the system boot, here is a piece of the report with an error:

You can try, maybe it will help you, if you don’t know how to do it, then look at the article.

This means the main reason is damage to the boot sector on the system partition.

By the way, if you had system recovery enabled on your computer, then you can try performing a system rollback. I wrote about this in the article. It says how to do a rollback by booting from the installation disk. But on this computer recovery was disabled :(.

I remembered that for such cases I have an installation disk with Windows 7 (assembly) in which many different programs are integrated, including those for working with the hard drive. This disc has saved me more than once.

I launched this disk and looked at what we have there to work with the hard drive. Selected “Check Disk (chkdsk)”. I decided to check the disk for errors.

A window appears in which you need to select a partition to scan. I have a section C was listed as reserved by the system. We don't need it, so we choose D, this will be the system partition. Leave a mark next to “Automatically fix bad sectors”. And press “Ok”.

The system rustled with files, in the process there were records that Windows was deleting, transferring and restoring something. When the scan ended, among the rest of the text (report) I saw “Windows has made corrections to the file system.” Okay, I thought and rebooted the laptop.

And everything worked, Windows 7 booted and there was no error 0xc00000f!

But I don’t have such a boot disk, what should I do?

I understand that you most likely do not have this assembly. You can do the following: you can download it, here is a link to the website of the author of this assembly (there are links to torrents below). Download and burn the image to disk, as written in the article. Boot from it and do everything as I showed above. And this disc will come in handy more than once, believe me.

In fact, all these actions can be launched from the command line by booting from the Windows 7 installation disk.

But you will still need the Windows installation disk.

Do everything as written in the article.

Just don't enter the command C: and instead of those commands run the command chkdsk c: /f /r and just in case chkdsk d: /f /r. We execute the commands one by one, enter the command and press “Enter”.

If a message appears that “Cannot lock the current drive,” enter Y(yes) and click “Enter”.

Afterword

This is how I got rid of error 0xc00000f without reinstalling the operating system. I hope that my advice will be useful to you. Well, if nothing works, then perhaps you have another reason for this error. All the best and fewer such problems!

Error 0xc00000f in Windows 7 [Solution] updated: June 9, 2013 by: admin

Sometimes when installing Windows, including version 10, an error message is displayed on the screen. The text of the message is: “Windows cannot be installed on this disk.” In this case, the hard drive is displayed in the BIOS. It is also visible at the stage of installation of the operating system, where it could be divided into sections.

This problem occurs for two reasons:

  • the controller is disabled in the BIOS (AHCI mode);
  • The hard drive has a GPT volume.

Problem with AHCI mode

In addition to an error message informing you that it is impossible to install Windows 7 or 10 on this disk, if there are difficulties with the AHCI mode, the computer cannot boot from the selected disk. The reason is that the controller may be disabled in the BIOS.

The problem is solved as follows:

Problem with GPT format

Another reason for the impossibility of installing Windows 7 or 10 versions with the display of a similar message may be GPT - the hard drive partition format.

Until recently, all hard drives were the same type. The only partition style was MBR. Over the past few years, manufacturers have been gradually switching to producing hard drives with the GPT format. But the boot files from the OS are not modified for new formats, and as a result, the error described above appears during installation.

The MBR (master boot record) is the program code and data required to pre-start the computer. They are located in the initial marked sector of the hard drive. The MBR starts after the initial BIOS analysis of the performance of all devices. Its main function is to determine the location of the files that are needed to boot the OS.

GPT is a new standard for the volume table layout format. A standard firmware interface for computers was also developed, replacing the BIOS. It is called UEFI (Unified Extensible Firmware Interface).

The problem occurs because the OS installer cannot install Windows on the specified partition due to the fact that the partition table does not suit it.

There are 2 methods to solve the problem:

  • installing the system on a similar disk;
  • Converting a partition to MBR.

The choice of method should be determined by the following rules:

  • if your computer supports the UEFI interface and you need to install a 64-bit OS (for example, Windows 10), then it is recommended to use the first option. Checking the presence of a UEFI interface is very simple. Graphics mode with mouse control indicates the presence of UEFI;
  • If the computer was manufactured several years ago, has a BIOS and requires installing a 32-bit operating system from MicroSoft, then you should convert GPT to MBR.

Using MBR limits some features, such as:

  • their volume cannot exceed 4 TB;
  • The maximum number of volumes on the HDD is limited to 4.

Installation of Windows 7, 8 and 10 on GPT

Problems when installing an OS on a GPT volume usually arise for those who want to install Windows 7, 8 and 10.

To install the OS on a GPT volume, you must meet 2 conditions:

  • install a 64-bit system (for example, Windows 10);
  • boot in EFI mode.

If the first condition is not met, you must prepare a bootable UEFI drive.

But in most cases, only the second condition is not met. Therefore, it is better to immediately go into the BIOS and check the settings.

There are two parameters to set in the BIOS:

  • enable UEFI boot;
  • switch the operating mode from SATA to AHCI.

After saving the settings, you can install the OS on your computer. The mistake will not happen again.

Converting GPT volumes to MBR

There are several options for converting volume style. Let's look at them in more detail.

Converting to MBR when installing Windows via the command line

This method is optimal for use in situations where installing an OS such as Windows 7, 8, 10 is not feasible due to the GPT volume type. It can also be useful not only when installing the OS, but also during the normal operation of the OS for converting non-system partitions.

It should be remembered that when converting partitions, all information from them will be lost. Therefore, it is recommended to save everything important on an external storage device in advance.

To change the style of volumes from GPT to MBR via the command line:

  • run the command line in Windows as a user with administrator rights;
  • to display a list of hard drives connected to the computer, enter the commands “diskpart” and “list disk” in sequence;
  • select the disk to change the style with the command “select disk D”, where D is the disk number;
    Then two scenarios are possible.
    1. perform a complete disk cleanup using the “clean” command. In this case, all HDD volumes will be deleted;
    2. You can delete HDD volumes one at a time using the commands “detail disk”, “select volume” and “delete volume”;
  • start converting the disk to MBR with the “convert mbr” command;
  • exit Diskpart by selecting “Exit”. Close the command prompt. After this, it is recommended to continue installing the operating system. This error message will no longer appear.

You can create volumes on the HDD by selecting “ Set up disk».

The volume style change is complete.

Changing partition style from GPT to MBR using Windows Disk Management

An alternative method for converting volumes requires a normally functioning Windows 7, 8 or 10 operating system on a personal computer. You can only convert a disk volume that is not a system one.

The sequence of steps to convert a HDD volume is as follows:


Utilities for changing partition style

In addition to the standard methods for converting HDD volumes provided by Microsoft developers, you can use third-party hard drive volume management utilities, such as

Users encounter Windows installations more often than they would like. Thus, the fact remains unchanged that various types of errors may occur, after which Windows 7 will not install.

We will not consider special cases of malfunctions, but rather their main types and methods of elimination. To structure the search for a problem, you need to break down the possible causes into main categories, and by going through them one by one you will find your problem.

So, why won't Windows 7 install? – there are quite a lot of problems, but we will highlight the main ones:

  • The problem is in the Windows distribution itself, especially if it is a repack;
  • Problem with installing Windows on a flash drive/disk, that is, some kind of failure in the boot record;
  • The problem is in the flash drive/disk itself and the drive;
  • Incorrect BIOS settings or outdated BIOS.

So, in order to determine why Windows 7 won’t install, the error can be completely different (it’s better to look for it specifically in order to narrow down the reasons why the problem arose), you need to gradually go through each item, which is what we’ll do.

Faulty Windows distribution

The problem may occur if you booted Windows from outside. Since the “master” can be very different, you can expect any outcome. Although there is nothing left but to download the OS from another source.

A typical manifestation of such a problem is the presence of errors during installation, especially if it constantly occurs in a certain place. It may also be that the flash drive does not show the option to install Windows 7 at all, but this may not be the only reason.

To definitely not consider this option anymore, use the original disk or try loading a different image. Also check that you have installed it correctly.

Windows 7 cannot be installed from a flash drive/disk

Here you should make sure that the information on the media is correct. This problem is very common, as it occurs due to the use of defective or inappropriate programs to create an installation flash drive. You need to use another application, here are the ones that should work: WinSetupFromUSB or UltraISO.

Usually, if there were any failures during the recording process, then you will not see the flash drive at all as a launch medium or various errors will arise during the process: the absence or malfunction of some files.

The same applies to a DVD that was not recorded correctly or that errors occurred during the burning process. Here you should burn the disc again, only using the minimum speed, because this prevents many problems.

Windows 7 won't install - faulty media

The problem is relevant both for DVD discs (more often) and flash drives (less often). This usually means that the disc is too scratched or not recorded properly, or there may be some mechanical damage. The situation is similar with a flash drive, check its functionality on another computer, in particular, try writing/copying several files. Using a standard check (RMB-Properties-Service-Check Disk), make sure that it is working properly.

Also try, in the case of a flash drive, to use the rear USB connectors since they have direct access to the motherboard, those on the front side use an extension cord, which may cause problems.

When using a disk, you should be sure that the disk drive itself is working properly, since in a situation where the laser loses power, there may be failures in reading information, and this will lead to an error.

These problems are characterized by a situation where they are not displayed at all in Windows or failures constantly occur in a random place (in the case of a disk drive).

Why won't Windows 7 install? BIOS problem

The first reason is an outdated BIOS. Thus, it has lost its relevance and can no longer perform some modern tasks, for example: older versions do not support large volumes of media. It is better to update the BIOS or you can use stripped-down media or Windows.

When using USB 3.0, problems are possible when Windows 7 drivers are not installed, since it is generally not designed to use this standard. A problem occurs when installing the original version. A solution can be found if you use additional drivers or third-party OS assemblies. You can also physically switch the drive to a connector with USB 2.0 or disable USB XHCI Controller in the BIOS, and for external HDDs - AHCI.

Also, if Windows 7 is not installed on a laptop, then you should disable the Secure Boot option, which is used mainly in Acer and Asus, but often works in others.

So, we found out what to do, Windows 7 won’t install for technical reasons, but it’s also worth mentioning that sometimes protection against installing a system other than the preinstalled one is simply turned on.

We have figured out what to do if Windows 7 is not installed on your computer, so even if you have not yet encountered such a need, you will be ready to identify and fix the problem at any time.

Reinstalling the operating system is a common and routine task for many. If no problems arise, then OS installation will not cause any difficulties and will be completed fairly quickly. However, in some cases, during the installation of Windows 7, the system displays an error.

Main causes of problems

Often, problems when installing an operating system arise due to the user's incompetence, because he forgot to format the disk, used a scratched DVD, or incorrectly recorded the installation distribution. But in some cases, the human factor does not play a role in their occurrence.

The main reasons why Windows 7 installation is interrupted are:

  1. The occurrence of equipment conflicts;
  2. Incompatibility of computer devices;
  3. Damaged storage media (from which or on which the installation is being performed);
  4. Problems with built-in drivers and hardware support;
  5. Incorrectly embedded license code or activator into the distribution;
  6. Using old software that does not support modern devices.

Almost all conflicts lead to a blue screen appearing on the monitor screen during OS installation, indicating an error code.

How to understand what the problem is?

Depending on at what point during the installation from a flash drive an unexpected error occurred, you can use an elimination method to determine the problem that caused it. You can also find out the cause of the error when installing Windows 7 from a flash drive using the code displayed on the blue screen.

If a failure occurs while copying files or before selecting a hard drive partition for installation, the problem most often lies in damaged media. Then you need to use a program to test the hard drive for bad sectors. In this case, errors may not be displayed on the screen, and copying and reading information will be very slow, which may lead to the process being interrupted altogether.

Often the reason lies in the recording of the distribution or the media on which it is recorded. This mainly applies to CDs, as they are often scratched and damaged. As a result, problems with installing Windows 7 can arise at any moment, both at the stage of copying files, and during their unpacking and installation.

Often, a failure can occur due to the use of an incorrectly formatted flash drive, for example, if the wrong file system format is selected. Errors also occur due to the use of USB 3.0 ports, support for which is most often not available in the distribution due to driver mismatches. That is, the BIOS will see the device and allow it to be launched from it, but the installer itself will not start or will fail while determining the system configuration. If USB ports can operate in two modes, this also leads to a hardware conflict and blue screen display with error codes.

Problem solving methods

If an unexpected error occurs while installing Windows 7 from a flash drive, do not rush to panic. To get started, try one or more of the following:

  1. If the installation was started from a disk, try wiping it with a dry cloth or napkin and repeat the operation;
  2. If the installation process is interrupted and the system displays a blue screen error, do not rush to restart the computer, write down the message code. This will help you find out the details of its origin;
  3. If you are using a USB flash drive as installation equipment and cannot boot from it, try using a different USB port (black);
  4. If you encounter problems while copying files, when the system generates an unexpected error, test your hard drive for errors;
  5. If a blue screen appears after completing the first stage of installation and rebooting the system, then the problem is due to driver incompatibility. To fix the problem, you need to disable all equipment that is possible, or use a different distribution;
  6. If you receive a message indicating that an unexpected error occurred, we recommend that you restart your computer and try again;
  7. It happens that a black screen or a window with a flickering cursor appears in front of the user, then you need to wait 5-10 minutes. If the situation does not change, then the system cannot read the settings or video card drivers.

If none of the above helped, try resetting the Bios program settings or use a different distribution and another flash drive to install Windows 7.

Result:

If the operating system gives an error when installing from a flash drive, this is not a reason to panic. Consistently repeat the operation and follow the advice. In most cases, when there is no physical damage to the equipment, problems can be avoided or a solution can be found.

Installing Windows 7 is an almost completely automated process. The minimum participation and no special training is required from the user: Microsoft's efforts have made installing the operating system as easy as installing a regular application. In most cases, the installation process goes smoothly - there are no failures or conflicts with the equipment. The “Seven” distribution kit includes a large set of drivers for various devices, so it can be installed on almost any hardware without any problems.

However, errors still sometimes occur during or after installing Windows 7. In some cases, they arise due to hardware malfunctions, in others - due to incorrect initial computer settings, which is especially typical for UEFI-based PCs, in others - due to defects in the distribution media and problems during its recording. Let's take a closer look at several common Windows 7 installation errors: what causes them to appear and how to solve them.

Error 0x80300024. “System installation cannot be performed at this location.”

Error code 0x80300024 indicates that the selected hard drive partition for some reason is not suitable for installing Windows 7. The reasons may be the following:

  • hard drive layout errors;
  • insufficient free space in the partition;
  • incorrectly selected MBR disk partition type: an attempt to install Windows 7 on a logical partition instead of the main one;
  • Incorrect UEFI settings (in BIOS emulation mode) when installing the system on an MBR disk.

Solution

Make sure there is enough space in the section where you are placing the system. For 32-bit Windows 7 home editions (home basic and premium), you need to allocate at least 15 GB of free space, for 64-bit – at least 20. Professional, corporate and maximum editions of “seven” will require twice as much space.

If you are installing to an MBR disk, make sure that the selected partition is of the “primary” type and not logical. If this is not the case for you, the disk needs to be repartitioned. Let's use the Diskpart console utility - it will help you change the partition type or create a new one without interrupting the installation progress.

  • To launch the Shell, press F10+Sift on your keyboard and enter the following commands one by one: Diskpart(launch the utility of the same name) >> List disk(showing all drives installed on the computer - hard and virtual disks) >> Sel disk 0(select disk 0 – on which Windows 7 will be installed) >> List part(display the list of sections).

In our example, disk 0 has 3 primary partitions and 1 logical partition. When installing the system into a logical partition, the above-mentioned error occurs, when selecting one of the main ones (suitable for capacity), everything goes smoothly.

  • To clear the disk partition structure, run the command clean(all markup, as well as all data will be destroyed).
  • To create a new primary partition (for the system), run the command create part primary size=N, where N is the size of the partition in megabytes. To allocate, for example, 50 GB for Windows, you need to specify the number 50000.
  • Next, the created partition needs to be formatted. Run the command format fs=ntfs label=”Windows”(NTFS file system type, volume label “Windows”).
  • Next command - active will make the section active.
  • Let's assign a letter to it: assign letter=C(assigned the letter C). The system partition has been created.
  • On the remaining unallocated disk space, we will create an extended logical partition for storing files. Let's run the commands: create partition extended and then - create partition logical . If you need to create several partitions of a given size, specify the size in create partition logical (parameter size=N) and repeat the command the required number of times.
  • Next is formatting and assigning a volume label: format fs=ntfs label=”My_Files”(the label can be anything).
  • And the last thing is to assign a letter to the section: assign letter=D. Now our disk is completely partitioned.
  • To close the console window, run the command exit.

When installing Windows 7 on a machine with UEFI, error 0x80300024 can occur in one more case: when in UEFI, in the Boot tab, a flash drive or DVD is assigned as the first boot device. Such settings are set in the BIOS to start the PC from external media, but in UEFI this is not necessary. In the “Boot priority” section of the Boot tab, the hard drive must be selected. The distribution media is indicated further in the “Changing boot” section (in our example, it is a flash drive, the third in the list of devices). To start the installation, just click on it.

Error “Windows cannot be installed because the disk has a GPT partition style”

Hard drives formatted using the GPT standard support installation of only two types of systems: Windows 8 (8.1) x64 and Windows 7 x64. It will not be possible to install a 32-bit “seven” on such a medium. But this doesn't mean you have to buy a new hard drive - the GPT partition style can be converted to a traditional MBR. The only negative is that not all of the capacity of a large hard drive will be used, since the MBR style allows only 2.2 TB to be addressed. The remaining space, if any, will become inaccessible.

Diskpart will also help us change the markup style. To convert, the hard drive will have to be completely erased, so transfer the necessary data from it to some other drive. After that, launch the command console and follow all the steps in the previous paragraph up to the command clean, including her. Next command: convert mbr– GPT markup style is converted to MBR. The subsequent steps - creating partitions, formatting, assigning letters and everything else - are performed in the same way as shown above.

Error 0x80070570 “Windows cannot install required files”

Error 0x80070570 when installing Windows 7 appears at the very beginning - at the stage of copying distribution files into the computer's memory. Most often it is called:

  • damage to the distribution media (scratched DVD, broken flash drive, etc.);
  • damage to the system files themselves on the media;
  • RAM malfunction.

The crash occurs because the system installer cannot access any important file due to its unreadability. As a result, the installation process is interrupted.

Diagnostic methods and solutions

  • Try installing the system from another medium, if you have one, and, if possible, test the distribution on another computer.
  • When burning a system image to DVD yourself, use the minimum speed (the quality of high-speed burning is often poor).
  • When you are sure that the media is in order, but the error still appears, check the RAM. If your PC has multiple RAM modules, remove one of them and try installation again using the remaining ones. If the error occurs again, remove the next module, etc. Install them in different slots and in different combinations.

Check each strip in this way. The one that causes the failure must be removed or replaced. After this, this problem will no longer bother you.
