Hi, I'm fixing some computers here, but they are not like mine in that it has xp pro, it has Media center edition, the hard drive needs cleaning, you can't get to the desktop, or get to the recovery. His serial is stuck onto the side of his case, but he has no disks or recovery disks, so I'm thinking, use a media center edition CD and format the drive, but I'm not sure it's that strait forward. What do I do? The other pc gets to the recovery page, but then it asks for the gateway recovery disks, which I don't have, all I have is a serial on the case.
