Fix 1: Remove the peripheral devices
The first quick fix you can try is to unplug any unnecessary peripheral devices from your PC and try to install Windows 10 again. For example, scanners, printers, a secondary monitor, speakers, etc. When any of these devices uses a generic driver, it may interfere with the installation and cause the “Windows 10 installation has failed” error.
If the installation proceeds and turns out successful, you can plug the devices back in after your system gets updated. But if this doesn’t help, try the next fix.
Fix 2: Clear an attribute of $WINDOWS.~BT installation folder
The “Windows 10 installation has failed” error could be triggered when the installer tries to repeatedly copy the files in a certain folder. You can try to clear an attribute of the $WINDOWS.~BT installation folder to see if it solves your problem. Here’s how:
- Press the Windows logo key and E to open the File Explorer, and navigate to the C drive.
- From the toolbar, click View and make sure you tick the checkbox of Hidden items.
- You should find the $WINDOWS.~BT folder here. Right-click it and click Properties.
- Uncheck the checkbox of Read-Only, then click Apply and OK.
- Run the installation again.
If this fix doesn’t solve the installation error you have, try the next fix.
Fix 3: Uninstall the language pack
The “Windows 10 installation has failed” error may be triggered when the language pack of your previous Windows iteration is not the same as the localization. If that’s the case for you, you may need to remove the language pack. Here’s how:
On Windows 10
- In the search bar on your taskbar, type language, then click Language settings.
- Make sure your Windows display language is set to English.
- Remove all the non-English language packs you have.
- Run the installer again.
On Windows 7
- Click the Start button. Type language in the search bar, then click Change display languages.
- Click Install/uninstall languages. You may be prompted for permission, just click OK.
- Click Uninstall display languages.
- Remove any non-English language packs per instructions. Make sure you save the changes.
- Run the installer again.
If this doesn’t solve your problem and you keep running into the error, try the next fix.
Fix 4: Rebuild the Boot Configuration Data
Any error found in Boot Manager could lead to the “Windows 10 installation has failed” error. The easiest way to fix the Boot Manager is to rebuild the Boot Configuration Data (BCD). It may seem a bit complicated, but the process is very straightforward. Here’s how:
The ways to enter Command Prompt are different for Windows 7 and Windows 10/8. You can follow the steps based on your Windows version to open Command Prompt first. The rest of the steps will work for all.
On Windows 10/8
- Press the Windows key, search for recovery, then click Recovery options.
- Under Advanced Startup, click Restart now.
- Click Troubleshoot.
- Click Advanced options.
- Select Command Prompt. You may be prompted to log in to your account at this step.
On Windows 7
- Restart your PC. When you see the manufacturer logo, keep pressing the F8 key to enter the Advanced Boot Options screen.
- Use the arrow keys to select Safe Mode with Command Prompt, then press Enter.
Once you’ve opened the Command Prompt window, follow the steps below:
- In the Command Prompt window, type in the following command lines. Make sure you press Enter after every command line and wait for it to complete.
- Close the Command Prompt window, and click Continue to exit to your desktop.
- Run the installer again to test the issue.
Fix 5: Perform a clean boot installation
Sometimes the programs on your PC may interfere with Windows installation. If you’ve got a specific error code, it’s likely due to an incompatible software or driver. Removing the problematic software or updating your driver may solve the problem.
But when that doesn’t help or you don’t have an error code, then you may run a clean boot installation to identify the cause and fix the problem. Here’s how:
- Press the Windows key, type msconfig in the search bar, and click System Configuration.
- Under the General tab, choose Selective startup, and make sure the checkbox of Load startup items is unticked.
- Go to the Boot tab, untick the checkbox of Safe boot.
- Under the Services tab, choose Hide all microsoft services, then click Disable all.
- Switch to the Startup tab, click Open Task Manager.
(If you’re on Windows 7, right-click anywhere empty on your taskbar to find the option of task manager.)
- Under the Startup tab, select every enabled startup item and click Disable until you’ve disabled all startup items.
- Restart your PC and try to run the Windows installer.
If performing a clean boot installation doesn’t solve the error for you, there’s one more fix you can try.

When the system files required for the Windows installation process are corrupted, it could trigger the installation error.
