I have a 64-bit Windows 7 factory installed Acer desktop. I downgraded it to Windows XP because I have an old tv tuner card that does not have Windows 7 driver. Now I have bought a new tv tuner that supports Windows 7, so I did a "alt F10" to restore my system to factory defaults. But after the system restore finished and rebooted, I received the following error message:
Windows could not start because the following file is missing or corrupt:
Please re-install a copy of the above file.
I have tried system restore 2 more times with the same error.
When I pressed F8 to get to Safe Mode, I see "Microsoft Windows XP Professional" as my only choice of OS. I thought it should be Windows 7 because I restored it to factory defaults.
Oh, I still get the same error message even if I select Safe Mode.
