I thought the upgrade from Windows 7 Home Premium to Windows 10 was successful until it rebooted. It now says Preparing Automatic Repair, Diagnosing Your PC, Automatic Repair couldn't repair your PC. I've gone into advanced options and nothing works. It won't roll back. Of course my niece can't find her OEM OS CD's.
Does anyone have a magic bullet other than Auntie buying W7HP from MS?
