Actually when in a dual boot one of the two items doesn't boot, "everything" is not OK, maybe "50%" is OK . AGAIN, there is NO SUCH thing as "A BLUE SCREEN ERROR" there is an uniquely identified BSOD with a given STOP ERROR number. Are you sure you are having the SAME 0x0000007b error you had with XP? : and not (for example) a 0xc000000e http://reboot.pro/13528/page__st__4 http://www.911cd.net/forums//index.php?showtopic=19439&st=0&p=137270entry137270 jaclaz Brother im getting uniquely identified BSOD error 0x0000007E plz help me thanks
