We couldn't update system reserved partition error while installing Windows 10 version 2004 update


My company has a old PC which was upgraded from Windows 7 to Windows 10 1703. Since, Windows 10 1703 is outdated now I am planning to upgrade the PC to the latest available version of Windows 10 version 2004.

First I tried to update the PC with Windows 10 updates but I was getting error repeatedly so now I tried Windows 10 upgrade tool but again I am getting the below error. We couldn’t update system reserved partition.
