I'm trying to recover the Windows password on a MacBook Air running boot camp. I have tried using Ophcrack, which I can get to run properly by booting the MacBook from a disc drive (by holding option key), but Ophcrack can't seem to find the partition that Windows is installed in, and therefore can't find the password location. I think the problem may be that the computer itself never gets into Windows mode, so I want to modify the BIOS within a Windows startup, to get it to boot from disk. But it seems that Macs don't have a BIOS at all, so I'm at a loss. Is there any way to start the MacBook in Windows and make it boot from the boot disk? If not, is there another way to recover the Windows password?
