I had a virus that infected my PC and now it says I have unrepairable files after a SFC scan. I even ran the dell factory image restore and still the same thing. I have two hard drive a (C) and (D) and a partition (E) on the (C). Can I reformat hard drive (D), and use my reinstall disk and reinstall vista to D and the switch drives so that it becomes my new C and then move all of my programs that were on the old (C that is now in the D location. I then reformat my old to make it my new (D)?
