1) Perform A Clean Boot And Run The Installation

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

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.

  • 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.
