For a lot of Windows users, the system BIOS (Basic Input Output System) is a place we’d rather avoid making any changes. It’s a scary, intimidating place where tiny changes can result in system failure. Even though the BIOS might be a strange place for beginner users, it's also a very important part of your system to get to know, especially if something has gone majorly wrong on your computer. In this guide, you’ll learn how to reset your BIOS back to its default settings. This is an important skill if you have accidentally made some changes you need to undo or if your computer has had some other BIOS related critical error.   

The good thing about BIOS is that on most computers, accessing it is very easy. To get to your BIOS, first, turn on your computer, as soon as it starts to boot start pressing the F10 key repeatedly until the BIOS screen appears. If this doesn’t work on your particular model, you can try F2 or F12 instead. If neither the F2, F12 or F10 keys work, watch your system very closely as it boots, you should see instructions on how to enter the BIOS displayed. If you still can’t figure out which key to press, try googling the BIOS key for your system. If you are using a custom built PC, Google your Motherboard brand and model for the answer.

Once you have pressed the correct key, your Computer will boot into the BIOS screen which will be quite a basic looking screen, void of any glamor. Most BIO interfaces will be limited to keyboard only function, however, some newer motherboards and computer builds are starting to include mouse support.
