2 Methods to Open UEFI BIOS Settings in Windows 8/10 & 11.


BIOS is a very known and popular small utility for computer devices. It provides Basic Input/Output Settings for system hardware and operating system. The BIOS settings are coded into a CHIP and used for configuring hardware settings, OS settings, BOOT settings, System Time & Date settings, and much more. The BIOS is the first piece of code that gets executed when the system starts. It performs the hardware tests and finds a suitable operating system to load. In this article, I will guide you on how to open BIOS settings in Windows 10, 8, 7, and Windows 11. However, you may see UEFI firmware settings instead of BIOS on your laptop. This is because UEFI (Unified Extensible Firmware Interface) is the advanced version of BIOS and will replace the BIOS later.

  1. It tests system hardware before loading the operating system. If everything is found OK, then it starts loading the operating system.
  2. It finds the capable operating system and passes control to the boot loader to load an operating system.
