Everytime i start my computer, it comes up with a black screen saying: Windows XP Professional could not start due to damage in/ or missing file: \WINDOWS\SYSTEM32\CONFIG\SYSTEM\ press r to repair, but nothing happens. It's a laptop and I have no XP CD for it. The computer came with XP on it, so all I've got is a product key on a label. I can't start it in failsafe condition or anything else when I use F8, it just goes back to the previous??? I can, however, enter the BIOS settings screen (F2), if that's any help. I was wondering if I could just delete the whole thing and use the product key or something to re-install XP??? Either that or any other help is very welcome!
