I tried to install windows Xp 32 bit on my desktop but it didnt work. I then tried a xp 64 bit cd and it worked. i thought there might of been something wrong with the disk but i tested it on my laptop and it worked. On my desktop, it wont allow me to boot from disk. So i decided to allow windows to load and then try booting the disk. The disk booted but it still didnt allow me to install it. I wasnt even able to click " Install Windows XP" . That part wasnt even highlighted. I bought a new harddrive thinking that was the problem but it turned out it wasnt. I was wondering if maybe its my motherboard. I went on other forums and other people said it could be a problem with my bios. Any ideas??
