I have a Dell XPS M2010 with duel hardrives. Before Dell replaced one harddrive, at the Dell logo page I given a choice which operating system I wanted Windows 7 RC, Vista Home Preinum or Windows XP. What steps can I take it restore the computer back. In addition Dell Tech support reinstalled Vista. In Computer section I still see drive C, D and F. Dell offered to help me for a fee of $250.00
