Here's a good challange. Windows 7 lost OS pwd & bios pwd - Microsoft Community

hey guys,

this first post, hello , thank replies.

i dug old laptop supposed have failed motherboard, delightful surprise boots fine. asus gl551. problem this...i not have admin access bios, user level access, cannot change boot sequence. then, don't have windows loging info either, , never setup admin account visible login screen. old boot sequence is: hdd, dvd, network....so no usb. further more, have tried boot other various operating systems, mint,  trinity, torrented win7, none of them boot, except official purchased win7, when boot , select "repair system" or whatever, error saying: "this version of system recovery options not compatible". can full format...i think...maybe not considering lack of bios access, have precious data on machine. if of guys can find magical workaround, appreciate it.

bios info: vendor - american megatrends ver. 204

thanks again.

nevermind, issue solved. anyway!

here's solution:

1. change date 2002/01/02 in bios user level account.
2. save , reboot.
3. when enter password window appears hit "alt + r", "enter rescue password" window appear, 2002/01/02 date showing (if not code won't work), enter following rescue password : alaa4aba
