Ok, I have WinXP SP1 installed. My drive is an IBM 180GXP 180 gig. It is one giant partition. I've been trying to reformat to get rid of the slowdown that has been coming over my computer but I when I boot from my XP setup disk and try to delete my one partition (so I can reformat/set up XP again), Setup denies it and says that the temporary setup files it is using are on that partition, so it cannot delete the partition. How can I get around this? Thanks in advance.
