I have a couple of old computers here that I'm not using, they originally had XP on them but I installed Linux on them to play with. I decided I need to reinstall WindowsXP and loan the computer to a friend temporarily. I put in the Windows install disk, it found an unknown partition on C so I had it delete the partition, make a new C partition, format the partition with NTFS and go on with the install. It acted like it was going OK but failed at some point in the install. I tried the other computer with the same problem, as well as trying to install on a couple of other hard drives that I had tried with Linux. So a total of 2 computers and 4 hard drives, that once had XP on them and I can't reinstall it. I'm thinking that Linux does something to the hard drives that Windows can't undo. I need suggestions on how to get XP installed and working.
