Unlocking a locked computer without password
I've been trying for hours to access my sister's Samsung RV510 laptop. The problem is that she does not remember the password at all. I have downloaded a third party program called Windows Password Key, burned it onto a USB drive, inserted it into the locked computer and tried to change the Boot order so I can start with the USB program without success. When the USB HDD drive is first in Boot priority order, the computer cannot start and Windows Boot Manager sends a report saying Windows failed to start, Status: 0xc000000f.
BIOS System: Phoneix Securecore Setup Utilitiy
Laptop: Samsung RV510
Is this a good question?
