I just got my computer working and when it boots up everything loads well but about 5 seconds into turning it on a thing comes up that says "DISK BOOT FAILURE. INSERT SYSTEM DISK AND PRESS ENTER" I've put in my Windows xp disc and nothing happens. I dont remember my motherboard coming with a disc so am i using the wrong disc? If i somehow dont have it can i download it somwhere and put it on a disc?
