  • Trying different slots

Fix Windows Cannot Install Required Files Windows 10

In this part, I will introduce mainly 11 ways to help you fix the Windows cannot install required files error when installing or updating Windows.

Unplug External Devices/Update Drivers

When you find the Windows 10 cannot install required files, you should try to fix it by disconnecting all USB devices and peripheral devices (including internet cable). The bad hardware drivers and outdated drivers are important reasons for causing Windows installation failure.

Your USB device is not required anymore after the files have been copied to the computer successfully. So you should remove it from PC. To fix the errors caused by outdated drivers, you must update the drivers to the latest versions.

Update BIOS

  1. Press Windows + R keyboard combination to open the Run dialog.
  2. Type msinfo32 into the text box.
  3. Press Enter to open the System Information window.
  4. Look for the BIOS Version/Date information (please write down the manufacturer and BIOS version if necessary).
  5. Go to the official website of the manufacturer and enter the computer serial number into the search box (you can also click on the auto-detect option if it has).
  6. Choose BIOS from the list of drivers to download the recommended update.
  7. Double click on the .exe file after downloading it successfully.
  8. Finish the update of BIOS according to instructions.

You must keep your PC connecting to the power source during BIOS updating. Otherwise, your computer may be damaged. It’s also possible that problems occur and you find you can’t boot PC after BIOS update; please don’t get worried, the MiniTool software will enable you to recover data and fix the problem.

Change a port

If you keep receiving this Windows installation error, you should consider that there is something wrong with your SATA port. Some users said they have fixed the problem simply by changing another port.

You should do the following things:

  1. Shut down your computer.
  2. Cut off the power supply.
  3. Open the case carefully.
  4. Connect the SATA cable of your drive to a different SATA port on the motherboard.
  5. Try to install Windows again.

But you should pay attention to this – if you have purchased a prebuilt PC, the action of opening the case will make its warranty invalid.

Change SATA to AHCI

  1. Boot into the BIOS by pressing the corresponding key (if you're not clear, please go to find the answer on the official website).
  2. Navigate to Drives and SATA Operation (the name will be a little bit different on different PCs).
  3. Change SATA to AHCI under Storage configuration.
  4. Exit BIOS and save changes.
  5. Turn off the computer and remove all external drives.

select AHCI

Change Hard Drive to IDE

Once your hard disk is configured to work as an AHCI device, you’ll run into the installation error when trying to install Windows 10.

To fix the problem in this case, you only need to:

  1. Restart your computer and enter the BIOS.
  2. Locate and change the mode to IDE.

Run System File Checker/Check Disk for Errors

Turn off Execute Disable Bit

If certain settings in BIOS are not appropriate, the Windows installation error will appear. Some users reported that it is the Execute Disable Bit setting that was causing the issue in BIOS.

Here’s how to fix:

  1. Restart your computer to enter BIOS.
  2. Find the Execute Disable Bit setting.
  3. Change the setting from enabled to disabled.

Confirm the Version of Windows

There are two types of Windows available for you: 32-bit and 64-bit. Most of the new hardware is based on 64-bit architecture. But if you’re using the 32-bit hardware and try to install a 64-bit version of Windows, you’ll fail obviously.

Therefore, I suggest you check the type of your motherboard and CPU by visiting the website of your manufacturer.

Make Sure SSD Has More Than One Partition

According to some users, the Windows cannot install required files message will appear sometimes when they try to install Windows 10 on an SSD which has a single large partition.

The possible fix is to create two partitions on the SSD drive before installing the Windows. I still have not a clue of how and why this happens.

In addition, you can also try the following methods that worked sometimes:

  • Try Windows Update troubleshooter.
  • Go to check the date and time settings.
  • Get a new Windows 10 ISO image file.
  • Activate default administrator account.
  • Modify the Windows Update installation files.
  • Reduce disk space of HDD or SSD & format it.
  • Re-write ISO (burn the image onto another USB drive).
  • Run memory diagnostic on your RAM and replace the bad RAM stick.

Guess you may be interested in another installation error – Windows could not complete the installation.
