Windows 10 installation process has become much easier over the years.

But sometimes you may have problems with the installation process like the installation can fail or the bootable device doesn’t get detected.

So, if your Windows 10 installation has failed after multiple attempts, check out this article to solve the issue.

What Are The Solutions If Windows 10 Installation Has Failed?

Now have a look at the methods described below when your Windows 10 installation has failed and then follow our step-by-step guide to install Windows 10 successfully.

1) Perform A Clean Boot And Run The Installation

Sometimes other programs and services may interfere while installing Windows 10 suite.

To avoid such situations, run the installation in a clean boot environment after your Windows 10 installation has failed a couple of times.

This will disable the third-party programs from starting up.

So, follow the steps given below:

  • Launch the Run utility by pressing Win + R hotkeys to. Now enter msconfig in the command box and press the Enter key.


  • You will get the system configuration window now. Click on the Services tab and check the box for Hide all Microsoft Services.


  • Click on the Disable all option. This will disable all the services that are running in the background.
  • Exit the window and right-click on your Windows Taskbar. Select Task Manager.


  • Click on the Startup tab and right-click on the Apps. Select the Disable option.


Finish the process and restart your PC. Now try to run the installation.

2) Disconnect All Peripherals

It is recommended to unplug all the peripheral devices attached to your computer (except the bootable media) like an external hard drive, printer, gamepad, scanner, etc, while you are installing Windows.

After completing the installation process, reconnect them. Often you may have conflicts during Windows installation due to these attached devices.

So, proceed with the installation [process after disconnecting the peripherals.

3) Check Disk Space

Often Windows 10 fails to install if you do not have enough disk space.

You will need a minimum space of 20 GB for 64-bit OS and 16 GB for 32-bit OS.

Now to clean up some disk space, click on This PC and check the disk space available on your system drive.

If you find that you do not have enough disk space, clean some unnecessary files and then proceed for Windows 10 installation.

4) Disable Firewall

Sometimes your Firewall protection may interfere with the installation process.

So, disable the firewall temporarily and they begin the installation procedure.

If you are using any third-party antivirus then disable that too for the time being.

Here I am showing how to disable Windows Firewall protection:

  • Go to the Start Menu and enter Windows Defender Firewall in the search box. Click on the top option.
  • Select Turn Windows Defender Firewall on or off option.


  • Click on Turn off Windows Defender Firewall (not recommended) option. Do this for both Private and Public network settings.


  • Now begin the installation process and if you still find Windows 10 installations failed, jump to the next step.

5) Remove Other Languages

If Windows 10 is failing to install after disabling Firewall, uninstall the language pack and then begin the installation process.

To uninstall the language pack, follow the given steps:

  • Click on the Start Menu and then select Settings.
  • Select Time & Language as shown in the picture below.


  • Click on Language from the left pane and then select all the other languages but English. Click on the Remove button.

Now try to install Windows. If you again encounter any error go to the next step.

6) Reset And Reboot The Boot Manager Service

The Boot Manager Service is directly related to the Windows installation or upgrade process.

So, while your Windows 10 installation failed, use the Command Prompt to run the Windows bootrec utility.

This will reset and repair the Boot configuration data and fix the problem.

  • You will have to use an installation drive if your Computer system is down.
  • So, use it to boot your device and when you get Choose your keyboard layout option, select accordingly.
  • As you find choose an option screen, select Troubleshoot as shown below.


  • Next, choose Command Prompt from the Advanced Options.


  • If you can access Windows UI then open settings and click on the Update & Security section.


  • Next select Recovery and from the Advanced StartUp option select Restart Now.


  • Next, choose Command Prompt from Advanced Command Prompt will open with administrative privileges.
  • Now, enter the following commands one by one. Press the Enter key after each of them:
bootrec /FixMbr


bootrec /FixBoot


bootrec /ScanOS


bootrec /RebuildBcd


After running the commands successfully, exit Command Prompt and restart your device. This should solve the problem with Windows installation.
