Hiya--On startup my Dell Vostro 220s running Windows 7 displays the login screen briefly, and then goes black. When I hit F2 or F12 ALL of the boot options are in brackets and disabled. I've found helpful material on how to change the order of boot options but nothing on how to change them from disabled to ENabled. It seems none of the system restore/repair/go back to factory image fixes will work because none of the media will boot.
I'd appreciate help on any way to ENable boot devices that can help get back to a windows operating system. DISabling them was ez/pz' enabling them--not so much.
