When I use my XP disc to try and erase my hard drive and reinstall XP, it tells me that it can't find my hard drive. Yes, I do have a hard drive and I am using it now, whch has all my programs and personal files on it like music; I also know the CD-ROM drive is working correctly because I have it set to boot from CD first. I do have the files backed up on a flash drive so I can reinstall my files. So, how can I have my CD see my hard drive to erase it & reinstall the OS?
