Sometimes you can’t install Windows 10 because of driver errors such as incompatibility with Windows 10 upgrade.

This solution helps fix the driver errors so you can try the installation again.

How to fix driver errors before performing a Windows 10 install

  2. Run Windows Update to download and install available updates including software, hardware and third-party drivers.
  3. Check for third-party drivers and download any updates available. You can find these on the manufacturer’s website.
  4. Unplug excess hardware such as external storage device and drives, docks, and any other hardware not necessary for basic functioning of your computer.
  5. Check Device Manager for drive errors by doing the following:
  • Right click Start
  • Select Device Manager

2. Keep your PC on and try installing again

When you can’t install Windows 10, it could also either be due to an interrupted upgrade process from accidentally restarting your PC, or you could also be signed out.

To fix this, try performing the installation again but make sure your PC is plugged in and stays on through the process.


3. Turn off VPN software and increase the size of System Reserved partition

Performing a Windows 10 installation can also fail when the computer can’t connect to Windows Update servers. Not having enough free space in the System Reserved partition also causes difficulty installing Windows 10.

If you’re using a VPN connection to connect to a work network, disconnect from the network then turn off the VPN software.

To fix the limited space issue, you can use a third-party software to increase the size of the System Reserved partition.

Try installing Windows 10 again.


4. Check for pending updates

Use this solution when your PC doesn’t have the required updates installed.

For a healthy computer, you need to keep updating Windows with the latest system updates, and drivers. This also helps resolve any issues or difficulties you may be experiencing.

Check to ensure all your computer’s important updates are installed before you try to install Windows 10 again.
