I have been having some major problems trying to reformat my hard drive and reinstalling WIN XP Pro. Hope someone can help!! I have two harddrives in my PC a 20 gig and a 160 gig. Win XP was installed on my 20 gig hard drive and in trying to reformat this drive and reinstall windows I have encountered some major problems. Here's what happens: 1) I first changed the boot sequence to boot from the CD drive. 2) With the Win XP cd in the drive I rebooted the PC which brings me to the blue Win XP installed screen. 3) I select the C drive, delete the partition, and then create a new partition in the standard NTFS format. 4) Once the drive has been repartitioned I proceed in attempting to installed Windows, but I keep getting a screen that says that my drive is not in a Win XP compatable format and that I must go back, delete the partition, and create a new partition. Soooooo I do this and when I try to installed Win XP I just get the same message again!! Now at first I thought that the problem might be a poor copy of Win XP, so I tried a different copy but that didn't work. I even tried using Win XP boot (floppy) disks and booting from my A drive, but that didn't work. So then somebody told me that the drive might be corrupt, so I went out and bought a new HD (120 gig) and tried again only to have the same error!!! What gives!! Oh, one more thing I have the drive that I am installing XP onto set at Master and my secondary drive set at Slave. I don't think this is the problem, but just as an FYI. Is there anything that I can do?? Any help would be greatly appreciated.
