Have you ever needed to tweak your computer’s hardware settings but didn’t know where to start? That’s where the BIOS comes into play. Whether you want to change the boot order, enable virtualization, or troubleshoot hardware issues, accessing the BIOS is your first step. If you’re running Windows 11, the process is straightforward—but only if you know how to do it.
In this guide, we’ll break down everything you need to know about entering the BIOS on a Windows 11 machine. We’ll cover what BIOS actually is, why you might need it, and step-by-step methods to access it safely.
What is BIOS and Why Is It Important?
A Quick Overview of BIOS
BIOS stands for Basic Input/Output System. Think of it as the brainstem of your computer—it’s the first thing that boots up when you press the power button. It initializes hardware and loads your operating system.
Why Do You Need to Access BIOS?
You might want to access the BIOS for various reasons:
-
Changing the boot sequence
-
Enabling or disabling hardware components
-
Setting a BIOS password for added security
-
Enabling virtualization for apps like VirtualBox or VMware
-
Updating firmware or troubleshooting boot issues
Preparing to Access BIOS in Windows 11
Save Your Work First
Before diving into the BIOS, make sure you save all your open files. The process usually requires a restart, and you don’t want to lose anything important.
Check Your Device Type
Is your computer a desktop or a laptop? Most methods work for both, but certain brands like Dell, HP, or Lenovo might use different keys for direct BIOS access.
Accessing BIOS via Settings in Windows 11
This is the easiest and most foolproof method for beginners.
-
Open Windows Settings by clicking on the Start menu and selecting Settings (or press
Windows + I). -
Go to System, then click Recovery from the sidebar.
-
Under Advanced Startup, click Restart now. Your PC will restart and show advanced boot options.

Type:
shutdown /r /fw /t 0 -
Press Enter, and your PC will restart directly into BIOS.
What If You Can’t Access BIOS?
Sometimes, no matter how many times you smash that key, nothing happens.
Possible Reasons
-
Fast Boot is enabled (skipping key detection)
-
Wireless or USB keyboards not detected early
-
Corrupted firmware settings
How to Fix It
-
Disable Fast Boot via Windows power settings.
-
Try a wired keyboard.
-
Update your BIOS/UEFI from the manufacturer’s website.
BIOS vs. UEFI – What’s the Difference?
Most modern Windows 11 machines use UEFI (Unified Extensible Firmware Interface), which is like BIOS on steroids. It’s faster, more secure, and offers a graphical interface. But people still call it “BIOS” out of habit.
Safety Tips Before Changing BIOS Settings
-
Don’t change what you don’t understand. Randomly tweaking settings can cause boot failures.
-
Take pictures of default settings so you can revert if needed.
-
Look for a Restore Defaults or Load Optimized Defaults option.
What to Do After Accessing BIOS
-
Adjust your desired settings carefully.
-
Save changes and exit (usually F10).
-
Your PC will reboot with the new settings.
Common BIOS Settings You Might Want to Change
-
Boot Order – Useful when installing Windows from a USB stick.
-
Virtualization – Enable this if you use virtual machines or Android emulators.
-
Secure Boot – Turn this on or off depending on your system requirements.
Can You Enter BIOS Without Restarting?
Unfortunately, no. Since BIOS loads before Windows, you’ll always need a reboot to access it.
Final Thoughts
Getting into the BIOS on a Windows 11 machine isn’t as intimidating as it sounds. Whether you go through the settings menu, use a hotkey, or run a quick command, the process only takes a few minutes. Just remember—BIOS is powerful, so treat it with care.
