The BIOS, also known as UEFI firmware on modern computers, is a low-level software interface that initializes your hardware before Windows starts. It allows you to configure important system settings such as the boot order, Secure Boot, TPM, virtualization, fan profiles, CPU settings, memory configuration, and storage options. Whether you’re installing Windows 11 from a USB drive, enabling virtualization for virtual machines, updating the BIOS, or troubleshooting hardware issues, knowing how to access the BIOS on an ASUS computer is essential.
On ASUS desktops, laptops, and gaming PCs, there are several ways to enter the BIOS. The most common method is pressing a specific key during startup, but Windows 11 also provides an option to reboot directly into the UEFI firmware settings. Depending on your ASUS device, the required key may differ slightly, and features such as Fast Startup can make entering the BIOS more challenging.
This guide explains multiple ways to open the BIOS on ASUS computers running Windows 11, including methods that work even if Windows fails to boot.
What Is the BIOS?
The Basic Input/Output System (BIOS), or UEFI firmware on newer systems, is responsible for preparing your computer’s hardware before Windows loads. It checks connected devices, initializes components, and hands control over to the operating system.
Within the BIOS, you can:
- Change the boot order
- Enable or disable Secure Boot
- Enable TPM
- Enable virtualization (Intel VT-x or AMD-V)
- Configure SATA or NVMe settings
- Adjust fan controls
- Monitor system temperatures
- Update BIOS firmware
- Reset BIOS settings to default
Most modern ASUS computers use UEFI firmware, which provides a graphical interface and mouse support.
Method 1: Press the BIOS Key During Startup
The easiest way to enter the BIOS is by pressing the correct key immediately after turning on your computer.
Steps
- Shut down your ASUS computer completely.
- Press the Power button.
- Immediately press the F2 key repeatedly until the BIOS screen appears.
For most ASUS laptops, F2 is the default BIOS key.
If you’re using an ASUS desktop motherboard, Delete (Del) is commonly used instead.
If the Windows logo appears, restart the computer and try again.
Method 2: Enter BIOS Using Windows Settings
If Windows 11 starts normally, you can reboot directly into the BIOS without pressing any keyboard shortcuts.
Steps
- Press Windows + I to open Settings.
- Click System.
- Select Recovery.
- Under Recovery options, click Restart now next to Advanced startup.
- Click Restart now again to confirm.
After your PC restarts:
- Select Troubleshoot.
- Click Advanced options.
- Select UEFI Firmware Settings.
- Click Restart.
Your ASUS computer will restart directly into the BIOS.
Method 3: Use the Shift + Restart Shortcut
Windows also lets you access the Advanced Startup menu using the Power menu.
Steps
- Open the Start menu.
- Click the Power button.
- Hold the Shift key.
- Click Restart while continuing to hold Shift.
After restarting:
- Select Troubleshoot.
- Click Advanced options.
- Choose UEFI Firmware Settings.
- Click Restart.
The computer will boot into the BIOS.
Method 4: Use the Login Screen
If you cannot sign in to Windows, you can still access Advanced Startup.
Steps
- At the Windows login screen, click the Power button.
- Hold the Shift key.
- Click Restart.
Once the recovery menu appears:
- Select Troubleshoot.
- Open Advanced options.
- Click UEFI Firmware Settings.
- Select Restart.
This method works even if you cannot access the desktop.
Method 5: Enter BIOS from Windows Terminal
Windows Terminal allows you to restart directly into the recovery environment.
Steps
- Open Windows Terminal as Administrator.
- Enter the following command:
shutdown /r /o /f /t 0- Press Enter.
Your computer will restart into the Windows Recovery Environment.
From there:
- Select Troubleshoot.
- Click Advanced options.
- Choose UEFI Firmware Settings.
- Click Restart.
Method 6: Disable Fast Startup
Fast Startup may reduce the amount of time available to press the BIOS key during startup.
Steps
- Open Control Panel.
- Click Hardware and Sound.
- Select Power Options.
- Click Choose what the power buttons do.
- Select Change settings that are currently unavailable.
- Uncheck Turn on fast startup.
- Click Save changes.
Restart your computer and try pressing F2 or Delete again.
Method 7: Use the BIOS Key After a Complete Shutdown
Instead of restarting, perform a full shutdown.
Steps
- Shut down your ASUS computer.
- Wait about 10 seconds.
- Press and hold the F2 key.
- While holding F2, press the Power button.
- Continue holding F2 until the BIOS opens.
This method works on many ASUS laptops with fast boot enabled.
Method 8: Use the Boot Menu
Many ASUS computers provide a Boot Menu that also allows access to the BIOS.
Steps
- Turn off your computer.
- Turn it back on.
- Press Esc repeatedly.
The Boot Menu appears.
From there, you can:
- Select a boot device
- Enter BIOS Setup (if available)
The exact options vary by ASUS model.
Method 9: Reset BIOS Settings (If Necessary)
If BIOS settings become corrupted, resetting them may resolve startup issues.
While inside the BIOS:
- Locate Load Optimized Defaults or Load Default Settings.
- Confirm the reset.
- Save the changes.
- Exit the BIOS.
The system will restart using the default firmware configuration.
Method 10: Update the BIOS
An outdated BIOS may cause compatibility or stability issues.
Visit the official ASUS support website.
Download the latest BIOS version for your exact model.
Follow ASUS’s instructions carefully when updating the BIOS.
Avoid interrupting the update process, as doing so may prevent the system from booting.
Common Reasons to Access the BIOS
Many users only enter the BIOS when necessary.
Some common tasks include:
- Installing Windows 11 from a USB drive
- Changing the boot order
- Enabling TPM 2.0
- Enabling Secure Boot
- Enabling virtualization
- Updating BIOS firmware
- Configuring storage settings
- Checking hardware information
- Resetting BIOS settings
- Troubleshooting startup problems
The BIOS provides access to hardware settings that cannot be changed from within Windows.
What If You Can’t Open the BIOS?
If none of the methods work, verify that you’re using the correct BIOS key for your ASUS model. Some laptops require Fn + F2, while most desktop motherboards use the Delete key instead of F2. Disabling Fast Startup can also make it easier to access the BIOS during startup.
If Windows still boots too quickly, use the Advanced Startup method through Windows Settings or the Shift + Restart shortcut. If your keyboard isn’t responding during startup, try connecting a wired USB keyboard directly to the computer instead of using a wireless one.
Which Method Should You Use?
If Windows 11 is working normally, using Settings > System > Recovery > Advanced startup is the easiest and most reliable method because it doesn’t require precise timing during startup. If Windows won’t boot, pressing F2 repeatedly on ASUS laptops or Delete on most ASUS desktop motherboards immediately after powering on the system is usually the fastest way to enter the BIOS.
Conclusion
Accessing the BIOS on an ASUS computer running Windows 11 is straightforward once you know the available methods. Whether you use the F2 or Delete startup key, reboot through the Windows Recovery Environment, or launch the UEFI Firmware Settings from Windows Settings, each approach allows you to configure essential hardware options. The BIOS is an important tool for tasks such as changing the boot order, enabling Secure Boot, activating TPM, configuring virtualization, and updating firmware.
If you’re unable to enter the BIOS using keyboard shortcuts, the Advanced Startup methods built into Windows 11 provide a dependable alternative. By following the steps in this guide, you can safely access and manage your ASUS BIOS whenever system configuration or troubleshooting requires it.
