I changed the setting so that it would boot from the cdrom drive. I restarted with the windows xp installation disk in the cd drive. I can't get it to run at all. This method works on my other desktop though. I repeated the process like 10 times already and nothing. is there another way to get it to install? I mean I have tried to install it by logging into my user account. It says that I can not upgrade my xp but I can install a new one. I have windows xp pro service pack 2. The one I'm trying to install is windows xp pro service pack 3 so that could be why. I did try installing it though and after I got to the dynamic update part, It stayed there for 6 hours even though it was only supposed to take 51 minutes.
