I recently installed Windows XP and it does not boot. It will get to the Windows XP blue scroll bar screen and that's it. It will keep scrolling forever. I have to shut off the computer there and click use last configuration. It will then work. When I first installed it, it worked fine, I think it may not work because I did a few tweaks I saw on the internet on my registry. But it may not be the case because my CD drive also is not functioning properly.
