How to Open BIOS: Step-by-Step Guide

1. What Does BIOS Mean?

Before we learn how to boot into BIOS Windows 11, it's important to understand what BIOS actually is. BIOS stands for Basic Input/Output System. It is a small program stored on your computer's motherboard that helps your PC start and communicate with hardware like the CPU, RAM, and storage drives. Think of it as the "brain" that tells your computer how to start up and run properly.

When you turn on your PC, BIOS performs a quick check of your hardware (called POST, Power-On Self Test) and then loads your operating system. Without BIOS, your computer wouldn't know how to start.

2. Why You Need to Open BIOS?

You might wonder why someone would need to enter BIOS Windows 11 or change its settings. There are several common reasons:

• Change Boot Order: Sometimes you need to start your PC from a USB drive or external device. BIOS lets you choose the boot device.
• Enable or Disable Features: BIOS allows you to turn on or off features like virtualization, Secure Boot, or integrated hardware.
• Troubleshoot Hardware Issues: If your PC has problems starting, BIOS helps check if hardware like RAM or hard drives are working properly.
• Update BIOS Settings: Advanced users can update system performance or compatibility settings here.

Knowing how to boot into BIOS Windows 11 gives you control over these important settings safely.

3. How to Open BIOS on Windows 11/10?

Now that you know what BIOS is and why it's useful, let's see how you can open BIOS on Windows 11/10. There are two easy ways: using the BIOS key during startup or accessing it through Windows Advanced Startup. Follow the steps below to get in safely.

Tip:

If you miss the key, restart and try again. Timing is important—press it immediately after turning on the PC.
