***SOLVED THE PROBLEM, THANKYOU FOR ALL THE HELP *** Ive had this computer for about 10 months, and had to put up with no system fans. I was messing around with my computers inside cables today, trying to get my system fans working for the last time. I got them working, but turned on the computer to be meet this gastly message. Verifying DMI Pool Data... "DISK BOOT FAILURE, INSERT SYSTEM DISK AND PRESS ENTER" Uh oh. I really DO NOT want to format my hardrive, I have too much to loose. Is there a way I can fix this, or is my hardrive already stuffed? Maybe I connected the wrong SATA cable...? Does the hardrive only need 1 cable connected to it? Ive only got a SATA sable connected to it, is there anything else I need to connect, because I can't find anything that would connect. Any help on this would be greatly appreciated.
