The fastest way to enter BIOS on an ASUS laptop

To open BIOS on an ASUS laptop, restart your computer and press Delete or F2 repeatedly as soon as you see the ASUS logo — before Windows starts to load. You have only a few seconds. If you miss the window, let Windows finish loading and restart again.

Most ASUS laptops use Delete or F2, but some models use F10, Escape, or Tab instead. If one key does not work, restart and try the next one. The correct key usually appears on the splash screen for a fraction of a second, so watch carefully during startup.

If you are having trouble catching the timing, you can also restart into BIOS from Windows itself without waiting for the startup window. This method is more reliable if your reflexes are not fast enough or if your keyboard is not responding during boot.

Key Takeaways

  • Press Delete or F2 repeatedly the moment you see the ASUS logo during startup, before Windows begins to load.
  • If Delete and F2 do not work, try F10, Escape, or Tab — the correct key varies by ASUS model.
  • You can restart into BIOS from Windows using Settings instead of waiting for the startup window.
  • Once inside BIOS, use arrow keys to navigate and Enter to select — your mouse will not work.

Entering BIOS from the Windows startup menu

If you cannot catch the BIOS key during the normal boot sequence, you can restart your laptop into BIOS directly from Windows. This method gives you more time and does not require split-second timing.

On Windows 10 or 11, hold Shift and click the power icon in the bottom right corner of the screen, then select Restart. Your laptop will restart into a blue menu with several options. Click Troubleshoot, then Advanced Options, then UEFI Firmware Settings. Your laptop will restart again and take you directly into BIOS.

This route bypasses the startup window entirely, so you do not have to watch for the logo or press any keys at the right moment. It is the most reliable method if you are new to BIOS or if your keyboard does not respond quickly during boot.

What to do if neither method works

If you cannot enter BIOS using either the startup key or the Windows menu, the problem is usually one of three things: your keyboard is not working during boot, your laptop is set to fast startup mode, or your BIOS is password-protected.

Try connecting an external USB keyboard and restarting. If the external keyboard works but your built-in keyboard does not, your laptop keyboard may need repair. If you are using the Windows menu method and it does not show UEFI Firmware Settings as an option, turn off fast startup: go to Control Panel, Power Options, Choose What the Power Button Does, then Change Settings That Are Currently Unavailable, and uncheck Turn On Fast Startup.

If BIOS asks for a password when you try to enter, you will need the password that was set when BIOS was locked. If you do not know this password, contact ASUS support with your laptop model number and proof of ownership — they can help you reset it, though the process varies by model.

Navigating BIOS once you are inside

Once you are in BIOS, your mouse will not work. Use the arrow keys on your keyboard to move between options, Enter to select, and Escape to go back or exit. The layout and menu names differ between ASUS models, but the basic navigation is the same on all of them.

Common sections you may see include Main (showing your hardware), Boot (controlling startup order), Security (password and encryption settings), and Save & Exit (where you leave BIOS). Do not change settings unless you know what they do — incorrect BIOS settings can prevent your laptop from starting.

To leave BIOS without saving changes, press Escape until you reach the main menu, then select Exit Without Saving. To save and restart, select Save Changes and Exit or press F10, depending on your BIOS version.

Common reasons to open BIOS on an ASUS laptop

Most people open BIOS to change the boot order so their laptop starts from a USB drive or external hard drive, to enable or disable hardware features like the touchpad or camera, or to check hardware information like RAM and storage capacity.

You may also need BIOS to enable virtualization features for running virtual machines, to adjust fan speed and temperature settings, or to reset BIOS to factory defaults if your laptop is not starting correctly. Some ASUS models also let you update BIOS from within the BIOS menu itself, though most updates happen through ASUS software in Windows.

If you are opening BIOS to troubleshoot a problem, write down what you see before making any changes. Taking a photo of the screen with your phone can help you remember the original settings if you need to change them back.

Restarting your laptop safely before entering BIOS

Before you restart to enter BIOS, close all open programs and save any work you are doing. Restarting while programs are running can cause data loss or file corruption, even though you are not shutting down completely.

If your laptop is frozen or not responding, hold the power button for 10 seconds until the screen goes black, then wait 5 seconds before pressing power again. This is a hard shutdown and should only be used when your laptop will not respond to normal restart commands.

Once your laptop is restarting, watch the screen carefully for the ASUS logo. It usually appears within 2 to 3 seconds of pressing power, and you have about 3 to 5 seconds to press the BIOS key before Windows starts loading. If you see the Windows logo instead, you waited too long — let it finish and restart again.

Frequently Asked Questions

What if my ASUS laptop goes straight to Windows and I cannot catch the BIOS key?

Use the Windows menu method instead: hold Shift, click the power icon, select Restart, then Troubleshoot, Advanced Options, and UEFI Firmware Settings. This takes you directly to BIOS without requiring you to press a key during startup.

Can I damage my laptop by changing BIOS settings?

Yes, incorrect BIOS changes can prevent your laptop from starting or cause hardware to stop working. Only change settings if you know what they do. If something goes wrong, restart and enter BIOS again, then select Reset to Defaults or Load Optimized Defaults to restore the original settings.

Why does my BIOS look different from what I see in online guides?

ASUS makes many laptop models, and each one has a slightly different BIOS version with different menus and options. The basic navigation is the same, but the exact layout and available settings vary. Your laptop model number is usually printed on the bottom of the case.

Do I need to enter BIOS to update my ASUS laptop?

Most ASUS laptop updates happen through Windows using ASUS software or Windows Update. You only need to enter BIOS to update the BIOS itself, which is rare — most laptops go years without a BIOS update. Check the ASUS support website for your model to see if a BIOS update is available.

What is the difference between BIOS and UEFI?

UEFI is the newer version of BIOS. Most modern ASUS laptops use UEFI, though the terms are often used interchangeably. From a user perspective, they work the same way — you enter the same menu during startup and navigate with arrow keys and Enter.
