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.

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.
