Windows 10 provides its users with many options for configuration. Many of these configurations can be done from within the operating system itself. However, there are some settings on the desktop and laptop, which can only be changed from BIOS. BIOS is a software, which is inbuilt into the motherboard of the computer. It controls almost everything, like preboot security options and the boot order. It also decides when the Fn key will act as a function key and when it will act as a Media Control.    

However, you can’t enter BIOS Windows 10 directly. In some of the older computers where the boot-up process is slow, you will be able to access it in a pre-boot environment. Hence, when the computer is booting up, you can press the F2 or F3 key to enter the BIOS. 

Moreover, the computer which has come out in the past four years, they are very fast in their booting process. Hence, the F2 key process will not work on them. However, there are other steps for accessing BIOS.

What is Windows 10 BIOS?

Before moving on to describe the process of entering BIOS, you need to understand what BIOS is. You also need to know about its features. BIOS or Basic Input Output System is a pre-installed program on your computer. This is primarily present in the Windows computer. It helps in starting up the computers. This is the program that was installed in the Windows computer way before the Windows Operating system itself. 

When you are turning on your computer, the CPU checks if all the hardware and functioning properly by accessing BIOS. The loading of the operating system in the computer memory is also with the help of BIOS. Thus, the booting process is completed. 

When the computer is booted up, BIOS acts as a mediator for the CPU and the Input and Output devices. When the Operating System is running on your computer, it is not necessary for them to know all the hardware information. This is managed by BIOS. 

Functions Performed by BIOS:

The functions performed by BIOS are as follows:-


The most important function of BIOS is to check whether the computer hardware is working properly or not. This is done by the POST or Power On Self Test. When this process fails, then the computer starts indicating with beeping sounds that there is an error in the process. However, when the POST process is successful, the computer boots up successfully. 


When the POST process is successful, BIOS then proceeds and locates the OS of the computer. After that, when it finds the OS, it hands over the control to it. This process is called booting. 

BIOS drivers 

These are programs saved in the memory chips. The memory chips are erasable and non-volatile. The basic information about computer hardware is given by these BIOS drivers.   

BIOS Setup

The configuration of the hardware settings is permitted by the BIOS setup. It is basically a configuration program. This is also called the CMO setup. It includes:-

  1. Changing the booting order.
  2. Loading the BIOS Setup Default. 
  3. Setting or Changing the Date and Time.
  4. Changing Hard Drive Floppy disc, DVD or CD Settings.
  5. Check Memory Installed Status. 
  6. Creation or Deletion of the BIOS password.
  7. Change CPU settings.
  8. Enabling or Disabling the Quick POST.
  9. Change Memory Settings.
  10. View System Voltages.
  11. Change System Voltages.
