When you need to get into your computer's firmware setup, you can use one of these hotkeys or reboot to the BIOS through your operating system.

Windows or Linux may be your operating system of choice, but no matter which platform you choose, your computer's BIOS (Basic Input / Output System) is calling all the shots behind the scenes. The BIOS, sometimes referred to as UEFI firmware on newer computers, tells your PC what storage drives you have and which one to boot from and what components you have, among other key functions. To change your boot order, set a system password, disable ports or built-in peripherals, or even to overclock, you may need to go into the BIOS menus.
