I am helping a buddy with his comp. His XP partition was corrupted somehow? and it will not boot his windows XP. and as we tried to install windows XP again with a reformat disc it prompts a location to install windows. There is no spaces available to install windows, if you select enter and install it will blue screen, if you select delete partition it will blue screen. He has a western digital 2500JS hard drive. I used WDD diag tool and ran it and it had no errors, as well as checking the BIOS to check to see if it is recognized (which it is). Any ideas why we are having this problem
