BIOS is a term you must have heard often. In fact, it’s possible that for most of your hardware issues, the IT person may have suggested a BIOS upgrade before troubleshooting the hardware. What is BIOS? BIOS is an acronym for (Basic Input Output System) and is a piece of software that goes along with the PC’s motherboard.
In brief, it establishes a layer of communication between the hardware and the operating system. Thus, needless to say, the BIOS plays a crucial role in the functionality of your Windows 11/10 computer.
Why update the System BIOS
BIOS is, after all, a piece of software that needs to be regularly updated, just to the operating system or the apps in general. The updates typically incorporate enhancements and fixes, which will ultimately help the software maintain its compatibility with both hardware and other software. That being said, unlike most other apps, the BIOS needs to be updated manually, which is precisely what we will explain in this segment.
Most do not need to update the BIOS. If your computer is working properly, you do not need to update or flash your BIOS. In any case, if you wish to, we recommend that you refrain from attempting to update your BIOS yourself and instead take it to a computer technician who may be better equipped to do so. One needs to consider updating the BIOS only if they are facing some performance issues or other problems that necessitate updating the BIOS. One needs to be careful and know how to update the BIOS; else, it could brick your entire system.

How to change Boot Device in BIOS or UEFI?
BIOS or UEFI offers a dedicated section where the boot order of the connected devices or type can be changed. If you need to boot from a USB driver of an external hard drive, you can change the order here and save the settings. Next time the PC reboots, it will look for the connected devices first and reboot if it finds the boot record; else, it will fall back to the last option.
How to lock BIOS with a Password?
If you do not want anyone else to change the settings, putting a password lock in the BIOS is good. Every BIOS or UEFI has a security section where the BIOS password will be available. That said, if you ever forget the password, you will need to reset it. If it’s a laptop, check the manual. However, a dedicated Clear CMOS button is typically available on the rear of the motherboard cabinet. Resetting the BIOS doesn’t create any motherboard issues but clears any changes made to the settings.
