Windows 7 to Windows 10 Fails to upgrade

tom_oulius · May 1, 2021

I have been trying to upgrade a pc from windows 7 pro to windows 10 however after the upgrade is almost completed it says "0x8007001F - 0x20006 The installation was not successful. Error in Phase SAFE_OS during REPLICATE_OC". I have a Dell 9020, I've updated the drivers, unplugged unneeded usbs, used Windows 10 ISO but nothing seems to work. Any ideas on what I can do? Thanks a lot.
