How to update BIOS: step-by-step guide

The Basic Input / Output System (BIOS) is a chip that allows your PC to perform basic startup operations before the operating system even starts up. The BIOS ensures that the operating system is properly loaded into memory, which is critical for the efficient operation of your computer.

There are currently two BIOS standards - the traditional type and the newer UEFI chips. That being said, UEFI is becoming more and more common as it has created a universal standard for all major processor manufacturers.

You may have heard something about updating the BIOS, but the question always arises as to whether it is worth doing at all.

After all, if you do something wrong during the BIOS update, your computer will most likely be unusable. For example, if an accidental power outage or power outage occurs during a BIOS update, your computer may not boot at all.

Therefore, you should first check the release notes for the latest version of UEFI on the manufacturer's website to see if the new update adds the functionality you need. If there is no significant need to update the BIOS, then it makes sense to risk the update.

However, in some cases it is simply necessary to update the BIOS, for example, so that the motherboard can support the new processor or other hardware, or to improve the stability and performance of the system.

Protect Your Data

If you are an inexperienced user, you can completely screw up the BIOS while updating it. Thus, your data will become corrupted and inaccessible, and any attempt to correct it may lead to irreversible consequences.
