I will introduce the procedure to crisis recovery my HP Compaq laptop. I finally managed to recovery the BIOS with a help of USB flash disk. Please note that after you have installed Windows you will want to move the 1st boot drive to be the hard drive.īut after searching on the Internet and find there is a “crisis recovery” mechanism to recovery the BIOS even the CMOS don’t work. F10 will then save your changes to the BIOS it will then Boot from the CD drive (where you have put the Windows install CD). You then use the arrow key to select the CD drive then you use the + key to move the CD drive to the top of the list. You then use the arrow key to move from Main to Boot. If your Presario is like mine F10 right after you turn on the computer will start in the BIOS screen.
