Ok... I have an old-ish Dell Inspiron 2500...my little brother was playing 'runescape' and it froze then gave a BSOD... Now, I cannot boot into windows anymore. What will happen is this: Turn on computer> Shows 'dell' setup screen> Gives a black screen saying 'operating system not found.' If I leave the computer unplugged for a period of time (10 mins or so) It will show the XP bootscreen for 5-10 seconds, then Ill get a BSOD saying 'Unmountable drive volume.' STOP: 0x000000ED ...
