I have a laptop that when boots gets a Ntdll.dll error and the o/s will stop booting (XP Home), i've tried a fresh install but i get the same error and can get no further, so i thought i'd mount the corrupt hdd externally to another laptop, the hardware being used is recognised but there's no hdd icon in 'my computer'. The mounted hdd is turning as i can hear it spinning. Would the mounted hdd be faulty or is there another way to get another copy of the .dll to this corrupt hdd?
