Windows  11  –  Boot to BIOS

Defining about

Power On Self-Test:

A Power-On Self-Test (POST) is an operation initiated by a computer after it has been turned on but before it boots up the OS.

A power-on self-test (POST) is a set of routines performed by firmware or software immediately after a computer is powered on, to determine if the hardware is working as expected

  • Boot:

On Windows 11, a “clean boot” is a way to start the system with a minimal set of drivers and apps at startup. Usually, you would boot your computer this way to troubleshoot issues while running or installing applications (including games) or applying updates to discard conflicts with other components.

As part of the system requirements, alongside a Trusted Platform Module (TPM), a device also needs to have “Secure Boot” enabled to install Windows 11.

  • BIOS:

Basic Input/Output System, or BIOS, is a built-in program that boots Windows when you turn on your computer. It also manages the communication between your operating system and other devices like a mouse or keyboard. Finally, it allows you to troubleshoot and configure different settings

  • UEFI:

UEFI is short for Unified Extensible Firmware Interface that offers users a faster, sleeker experience. But before we get too deep into UEFI, it’s first important to understand what came before it: BIOS. Note: Newer PCs that already have UEFI might still call it the BIOS to avoid confusing consumers. So this is the reason, booting to BIOS in Windows 11 is slightly different from previous versions such as Windows 7. If you are searching how to go about it, here’s a short guide for you.

So first of all

Accessing the BIOS

There are two ways to boot into BIOS in Windows 11. One is through the Windows Settings and the other is to press down the Shift key while clicking the restart button in the Start menu.

Option 1: From the Start Menu

  • Click the Windows Start menu, then the Power button.
  • While pressing down the Shift key, click the Restart button.
  • This will take you to the Windows Troubleshooting options, where you can reboot to BIOS.

Option 2: From Windows Settings

  • You can access Windows Settings by right clicking on the Start Menu. Then navigate to the System > Recovery section.
  • In the Recovery settings, under the Advanced startup section, click Restart now.

Navigating Windows’ advanced startup options

  • After using either of the two options above, wait for the loading screen to complete and then click the Troubleshoot button.
  • Tap the Advanced Options section.
  • Then select UEFI Firmware Settings for BIOS settings.
  • The next screen provides an option to restart and access the BIOS setup page.

Upon booting, you will be presented with your UEFI settings. Please note depending on the device manufacturer, you may encounter different options from the ones listed below

BIOS provides access to multiple low-level settings to control hardware devices such as USB functionality, boot priority, secure boot etc. Most modern UEFI have integrated mouse input so that’s easier to navigate and select through the different settings.
