I have the Dell XPS M1330 and it came with Windows Vista Home pre-installed but I did a stupid thing and installed Vista Professional over it now I can't restore it to its previous state.
I can still see the restore drive but I can't seem to restore it? Any tips?
I want to restore it back to factory settings.
EDIT: When I reboot and press F8 I don't have any options for repairing my PC - boot to windows etc.
