Important info to know when troubleshooting
There are times when users exhaust all their options and resort to resetting their BIOS in order to fix their computer.
The BIOS can be corrupted because of an update gone bad or through malware. Learning how to reset the BIOS is important in the event that you’d need to troubleshoot your PC.
What is BIOS?
BIOS stands for Basic Input Output System. Every motherboard comes with BIOS. This software makes it possible for users to troubleshoot the computer.
Usually, computer technicians go into the BIOS setup to make adjustments to change the boot order or configure the keyboard control. It also provides a list of installed hardware like your hard drive, CPU, and RAM.
It doesn’t matter what operating system you use. Whether you’re running Linux or Windows, you will have access to the BIOS settings since practically every motherboard comes with one.
What is UEFI?
Newer computers have replaced BIOS with UEFI or Unified Extensible Firmware Interface. UEFI is faster and has improved security features compared to BIOS. Both terms, however, are often used interchangeably by most users.
Laptop BIOS vs Desktop BIOS: Is there a difference?
The process should be the same whether you’re accessing the BIOS in your laptop or your desktop. But do note that there are cases when users are locked out of their BIOS completely. This would require that your computer’s housing be opened which would void your warranty. In cases like this one, it would be best to leave it to professional technicians.
It does not matter if you’re running Windows 7, Windows 8, or WIndows 10. All modern motherboards have built-in BIOS.
How you access your BIOS would depend on your motherboard. There’s no real standard set so manufacturers tend to assign different keys. But whatever brand you won, getting into your BIOS settings start with a PC reboot.
While the computer is loading, repeatedly hit the key that gets you into BIOS. The load screen would sometimes leave hints as to what button to press. On most machines, it would be the F2 key but some laptops use DEL instead. Hit the right button enough times and the computer will load your BIOS settings.
Windows 10 users can also access BIOS using the Shift + Restart method. Go to Start > Power. While holding the Shift key, press Restart. This will bring up a blue window with several troubleshooting options.
From here, go to Troubleshoot > Advanced Options > UEFI Firmware Settings. Hit the Restart button to continue.
The computer will reboot but enter the BIOS at the end of it instead of bringing you to the login screen.
Resetting your BIOS settings
Once you’re in BIOS, hit the F9 key to bring up the Load Default Options prompt. Clicking Yes will be enough to restore the default settings.
You can also reset BIOS in the Security tab. Different motherboards have varying menu options but there will be one that would reset your BIOS.
Don’t forget to Save and Exit when you’re finished.
