Accessing the BIOS (Basic Input/Output System) or UEFI firmware on your Windows 11 PC allows you to manage hardware settings, boot order, security features, and more. Whether you want to change boot devices, enable virtualization, or troubleshoot hardware, knowing how to enter BIOS is essential. This guide walks you through all methods to access BIOS safely.
Why Access BIOS on Windows 11?
- Change boot order to install or repair Windows.
- Enable or disable hardware features like virtualization or TPM.
- Update firmware settings for hardware optimization.
- Troubleshoot startup problems or system errors.
💡 Note: BIOS settings are powerful. Incorrect changes can affect your system, so proceed carefully.
Method 1: Enter BIOS Using Startup Key
Most PCs allow BIOS access via a startup key:
- Shut down your PC completely.
- Turn it back on and immediately press the BIOS key repeatedly.
- Common BIOS keys for Windows 11 PCs include:
- Del or Delete – Desktop motherboards
- F2 – Laptops (Dell, ASUS, Acer, Lenovo)
- F10 – HP laptops
- Esc – Some HP and older PCs
- F12 – Boot menu key (sometimes provides BIOS access)
- You’ll see the BIOS or UEFI firmware interface.
💡 Tip: Check your PC manufacturer’s website for the exact key if unsure.
Method 2: Enter BIOS via Windows 11 Advanced Startup
Windows 11 provides an alternative method if the startup key is tricky:
- Press Windows + I to open Settings.
- Navigate to System > Recovery.
- Under Advanced startup, click Restart now.
- After restart, select:
- Troubleshoot > Advanced options > UEFI Firmware Settings > Restart
- Your PC will boot into BIOS automatically.
This method is reliable even on fast boot systems where pressing a key is difficult.
Method 3: Use Shift + Restart Shortcut
You can also use a keyboard shortcut to access Advanced Startup:
- Click the Start Menu > Power button.
- Hold down the Shift key and select Restart.
- After restart, navigate:
- Troubleshoot > Advanced options > UEFI Firmware Settings > Restart
- Your system will boot directly into BIOS.
💡 Tip: This is handy when your PC boots too fast for the standard key press.
Tips for Navigating BIOS/UEFI
- Use arrow keys, Enter, and Escape to navigate traditional BIOS.
- In UEFI, you can use a mouse and keyboard.
- Save changes before exiting (usually F10).
- Avoid changing settings you don’t understand to prevent boot issues.
- Look for Boot, Security, and Advanced tabs for common adjustments.
Common Issues and Fixes
- Cannot enter BIOS:
- Ensure you’re pressing the correct key at startup.
- Disable Fast Startup in Windows 11 settings.
- BIOS key doesn’t work:
- Try another key combination (Esc, F12, Del).

- Windows boots too fast to press BIOS key:
- Use Shift + Restart or Advanced Startup to enter BIOS.
Conclusion
Accessing the BIOS on Windows 11 is straightforward with either the traditional startup key or through Windows’ Advanced Startup options. BIOS/UEFI allows you to manage boot priorities, enable features, and troubleshoot hardware. Always proceed carefully, save changes before exiting, and consult your PC’s manual if needed.
