How to Enter BIOS on an ASUS Motherboard

To enter BIOS on an ASUS desktop motherboard, restart the PC and repeatedly tap Delete (Del) or F2 as startup begins, around the ASUS logo screen. If Windows starts too quickly, use Advanced startup → Troubleshoot → Advanced options → UEFI Firmware Settings → Restart. Save your work before restarting; neither method requires a download.

The firmware setup screen lets you inspect hardware information and access motherboard configuration settings before the operating system loads. On modern boards, this interface is usually UEFI, although people still commonly call it BIOS. Opening setup does not require you to change anything.

This guide focuses on ASUS desktop motherboards. For an ASUS laptop or a complete prebuilt PC, check that product’s instructions rather than assuming every ASUS device uses an identical startup procedure.

Method 1: Use Delete or F2 During Startup

ASUS documents Del or F2 at the ASUS logo during startup for its motherboard UEFI interface. See the official ASUS motherboard UEFI EZ Mode guide for the entry keys and an overview of the screen.

1. Save open files and restart normally. If the computer is already off, turn it on.
2. Begin tapping Del early, as the PC starts up. Continue through the brief ASUS logo screen rather than waiting for Windows to appear.
3. Wait for firmware setup. If Windows loads instead, let it finish starting and try another normal restart, using F2.

The useful window is during the motherboard’s startup checks, often called POST. Once the operating system is loading, pressing the setup key generally misses that window. A missed attempt does not by itself indicate a keyboard fault or a firmware problem.

Use one setup key per attempt so you can tell what worked. There is no need to try every function key, deliberately flood the keyboard buffer, or hold down the power button to interrupt a running operating system.

Confirm the Instructions for Your ASUS Model

The motherboard model matters more than a broad list of computer brands. A custom desktop can have an ASUS motherboard inside a case made by another company; the case logo does not identify the firmware instructions you need.

Use the model name from your purchase documentation, motherboard manual, or existing system records to locate its ASUS support page. Match the full model designation, including any suffixes. ASUS advises checking the exact model’s official technical specifications for supported UEFI features.

A startup prompt that says “enter setup” refers to the firmware configuration screen. A boot-device selection menu serves a different purpose: choosing a device to start from. If you reach a list of drives instead of configuration pages, consult the model instructions for the setup key.

Method 2: Use Windows Advanced Startup

If Windows works but catching the startup key is difficult, use the firmware restart option. ASUS provides this route in its official instructions for entering BIOS configuration, with guidance for Windows 10 and Windows 11.

1. Save your work. This process restarts the computer and interrupts your current session.
2. Search Windows for Change advanced startup options and open that settings result. In Windows 11, you can also open Settings → System → Recovery.
3. Under Advanced startup, select Restart now and confirm if prompted.
4. When the recovery menu appears, choose Troubleshoot.
5. Select Advanced options, then UEFI Firmware Settings.
6. Select Restart to enter firmware setup.

Use the menu labels to navigate rather than relying on their exact positions in a screenshot. The appearance can differ between systems. This route avoids having to time a keypress during POST, but it depends on the firmware option being available in Windows recovery.

If UEFI Firmware Settings Is Missing

A missing menu entry does not establish that your motherboard lacks setup access. A Windows installation using legacy boot mode is one possible explanation, but the absent option alone is not enough to diagnose the configuration.

Return to a normal restart and try Del or F2 during startup. If necessary, use the exact motherboard manual to confirm the entry procedure. Note whether the option is missing entirely or whether selecting it produces an error; these are different symptoms and useful details when seeking model-specific support.

Do not change CSM, disable Secure Boot, reset CMOS, or update BIOS merely to make this menu entry appear. Those actions change configuration or firmware and are unnecessary as first steps for opening setup.

If Windows Will Not Boot or the Keyboard Method Fails

The startup-key method does not require Windows to load. If the operating system will not start, ASUS directs users to keyboard entry. Try the setup key from the beginning of startup rather than waiting for an operating-system error screen.

If the key seems to be ignored, check the input connection before assuming the firmware needs repair:

• Try a wired keyboard if you are currently using Bluetooth or another wireless connection.
• Connect directly to a USB port on the PC, preferably a rear motherboard port, instead of through a hub, dock, or keyboard switch.
• Try another direct USB port and repeat the normal startup-key attempt.
• Check the keyboard’s function-key behavior if F2 also controls a media feature, or try Del.

These are practical troubleshooting steps, not guarantees that a particular keyboard or port will work before the operating system loads. Change one thing at a time so the result is interpretable.

If there is no startup display at all, you cannot reliably tell whether setup opened. Treat that as a separate display or startup issue and follow the motherboard’s troubleshooting guidance. Do not disconnect internal storage or deliberately create hardware errors to force a setup prompt.

What to Do Once BIOS Opens

On supported ASUS motherboards, setup may open in EZ Mode, with an overview of hardware and boot information. Advanced Mode is commonly accessible with F7; follow the onscreen labels because interfaces vary by model.

First identify the information or setting you came to inspect. Reading a displayed memory capacity or checking which drives are listed is different from changing memory profiles, boot order, or security settings. Record the original value before making any deliberate adjustment, and use the model manual to understand its effect.

If you only wanted to look around, choose the exit option that discards changes and read the confirmation prompt carefully. Do not select a save option out of habit. You do not need a BIOS update, a Windows utility, or a command-line shortcut simply to inspect setup.

Bottom line

Start with a normal restart and early taps of Del or F2. If Windows loads and timing is the obstacle, use its Advanced startup firmware route. When either approach fails, check the exact ASUS model instructions and the keyboard connection before considering configuration changes. Once inside, inspect what you need and exit without saving if you intended only to observe.
