Many users reported that Windows 10 installation is getting failed without any error code. The error code helps you understand what kind of error your device is facing so you can take appropriate steps to resolve it. But when there is no error code, you’re flying blind and it makes troubleshooting the situation somewhat difficult.

Still, it’s not impossible and we have compiled a list of solutions that will help you quickly resolve this problem and enable you to install Windows 10 on your device.

General Fixes

Before going on to try the fixes listed below, here are some general easy fixes you should try to resolve the installation error:

  • Remove any peripherals: If you have any non-essential external hardware peripherals plugged in, like headphones, USB devices, external hard drives, printers, scanners, etc., unplug them. They can interfere with the installation. If your laptop is connected to a docking station, also undock it.
  • Update Drivers: Make sure all the important drivers are updated before installing Windows.
  • Uninstall third-party anti-virus: If you’re using any third-party anti-virus software, uninstall it and use only Microsoft Defender, at least while you’re trying to upgrade the Windows. Third-party anti-virus software can often cause problems with Windows updates. Once the installation completes, you can reinstall the software. But make sure you have the required activation information before uninstalling so you can reactivate it.
  • Free Up Disk Space: You should have enough space on your hard drive so that the Windows installation can take place. If it doesn’t get the required space, the installation will fail. Check the disk space from File Explorer (or, Windows Explorer in Windows 7) and free up space if required.

Try updating Windows after performing these fixes. If you still see an error code, then proceed with the more technical fixes listed below.
