I have a HP EliteBook 6930p. This is an old laptop that I never used, now when I really want to use it I can't remember my password. So I have downloaded (OPHCRACK) unto an usb but for some reason I can't see to be able to boot from it. It won't show on my bios or anything. I have tried all usb ports which to me seem to be working because the light on the usb lights up. Can anyone here help me? Thanks for your time.
