The BIOS is a setup program for your computer. It is used to tell the computer how to start up, what devices to boot from, and how to load the operating system.
The BIOS is primarily used for configuring hardware. It also provides information about the current state of hardware devices, like the motherboard and hard drive, and it can be used for troubleshooting.
Let’s learn step by step how to open the BIOS on HP Laptop!

What is BIOS?
BIOS is an acronym for Basic Input/output System. It is a type of firmware that starts up the computer, performs self-checks, and passes control to the boot loader.
BIOS is a type of firmware that starts up the computer, performs self-checks, and passes control to the boot loader.
BIOS checks if all hardware components are functioning properly and if they are not it will display an error message.
The BIOS then passes control to the Boot Loader which can be either MBR or GPT depending on what type of disk you have in your system.
How BIOS Work?
What is the BIOS, and what does it actually do for your desktops, laptops, or tablets? There are 4 key functions that a BIOS performs.
- BIOS drivers
- Bootstrap loader
- CMOS setup
#1. BIOS drivers
A BIOS driver is a computer’s memory chip that houses numerous programs. Those drivers make your PC boot up and set up basic functionalities.
The POST test is a self-test in which your computer runs every time it is turned on. POST checks to see if there are any errors with your PC and checks to see if its hardware is working properly.
Everything in a computer, from its keyboard to its disk drive to its RAM speed and integrated ports, is checked by POST. In this case, POST will proceed as normal and your PC will begin booting normally.
#3. Bootstrap Loader
The process which lives within your computer’s EPROM or ROM is known as the bootstrap loader.
It is tasked with reading the boot sector of your hard drive as your PC’s operating system gets loaded.
Once Windows 10 has been loaded into memory, the bootstrap loader activates POST and the operating system.
Newer PCs use the Extensible Firmware Interface, or EFI, to replace the bootstrap loader.
#4. CMOS Setup
All low-level settings on your PC, like the system time and hardware configurations, are contained in its CMOS.
It means that CMOS is used to save changes you make to the BIOS structure. You can set your password, date, and time in the CMOS system.
