I have a computer that I want to get up and running, it was working fine then a major event happened, I don't know what exactly but one day it worked then the next it didn't, that kind of scenario!! Ghosts or whatever. Anyway, I took the hard drive out and reformatted and partitioned it on another XP computer but when I go to re-install on the original computer it stops during the setup part when it gets to the partition bit - it comes up as unpartitioned and if I push C to create a partition nothing happens. So it's been successfully formatted and set up on another computer but when I try to get it running on it's own computer suddenly it's not formatted. ??
