In case you ever get stuck with forgotten boot menu password, following experience might help. Yesterday while trying to reset my BIOS password for my CPU running on Gigabyte motherboard, i ended up in loosing up my current password and an alien password got set which prevented me from accessing my system. The computer was neither starting nor could be formatted as the boot menu itself was not coming.
Following google tip came to my rescue “SHORT the CLR_CMOS pins on the mother board”.
On your motherboard , while the system power is turned on short these 2 pins using a jumper or in case a jumper is unavailable, use any metallic object(with insulation) to short them(i used a pair of scissors). The system restarted and the boot menu was reset and there was no password to block my access to my system. If this did not work, read further for more options
3 Steps to reset your BIOS
- One of the following steps should work for you:
Unplug the computer from the power socket. Then check: If the motherboard is equipped with CLR_CMOS button then press it.
- If your motherboard has CLR_CMOS pins (Clearing CMOS) jumper then place a jumper cap on the two pins to temporarily short them or use a metal object like a screwdriver or even a scissor as i did) to short these pins for 5 seconds. Put the jumper back in its default position (open). Please note when you short the pins or place the jumper on them , the system should be turned on else nothing will happen.
- If above methods fail then you need to remove the CMOS battery (small silver disk) and then use method “2” and additionally wait for 10 minutes. Instead of waiting you can use a metal object like a screwdriver to touch the positive and negative terminals of the battery holder (NOT the battery!), making them short for 5 seconds. Replace the battery.
The CMOS is now cleared. Now you can plug the PC into the power socket, boot up into the BIOS, Load Optimized Defaults, save and exit.
