Well.. I have a problem. I bought a Compaq notebook yesterday with UEFI and windows 8.1. I managed to downgrade to windows 7 and in the end I tried to activate it using windows loader 222 but it isn't working. When I open the Windows Loader.exe in the status field I get the message << Unsupported partition table >> What should I do? Excuse me if my thread isn't posted where it should be. I'm not an experienced forum user. Thank you!
