7 ways to fix the error of not being able to enter the BIOS menu

Many factors can cause the BIOS (or UEFI) to become inaccessible, from the system freezing to not seeing the prompt appear.

If you can't get into the BIOS menu, here are some troubleshooting steps you can try.

1. Plug in a wired keyboard

Let's start with the most obvious reason. Normally, you would press the F2 or DEL key when you boot up to enter BIOS. But what if you see the prompt and press the keys but nothing happens?

The problem could be caused by using a wireless or Bluetooth keyboard. Many of these devices are not available at boot until you enter Windows, so keystrokes will not be registered.

The easy answer is to plug in a wired USB keyboard and use it to press the F2 or DEL key . You can plug the USB ports into the back of your PC as a precaution.

2. Use Windows Advanced Startup

It's possible that the keyboard is fine, but the BIOS is still unresponsive. To rule out a keyboard problem, let Windows boot into the BIOS for you.

Windows has an "Advanced Startup" feature that automatically enters BIOS on Windows 10 & 11 when you restart. On Windows 11, just go to Settings > System > Recovery and click Restart now next to Advanced startup .

After prompting you to restart the system this way, Windows will automatically take you to the BIOS menu.

3. Turn off Windows Fast Startup

Did you know that both Windows 11 and Windows 10 have 'Fast Startup' enabled by default? This feature works by secretly resuming Windows quickly from hibernation instead of going through the slower process of a cold boot.

The downside to this feature is that it can skip the BIOS boot screen. If for some reason you never see the BIOS prompt and your PC goes straight into Windows—even after a full shutdown—Fast Startup is probably the culprit.

To get back to normal booting with a BIOS prompt, turn off Fast Startup. You can turn off Fast Startup on Windows 11 and 10 by going to Control Panel and going to Power Options .

4. Switch the display to integrated graphics

Is the GPU causing the problem? If you have a monitor plugged into your GPU, your motherboard may suddenly go straight to loading Windows. Older motherboards don't work this way, but some newer boards will skip the BIOS prompt if they don't immediately detect output from the GPU.

To rule out this problem, go to where your monitor is plugged in. This method only works if your motherboard or CPU has integrated graphics.

Unplug the HDMI/DisplayPort cable from the GPU and plug it into the motherboard's graphics port. In a standard computer case, the integrated graphics port is usually located higher than the GPU port.

If this solution worked, the BIOS prompt should appear now and pressing the F2 or DEL key should give you access.

5. Connect the monitor to the first output of the GPU

This is a new issue that has arisen recently when you have a GPU and enable the "fast boot" setting in the BIOS. The motherboard will skip the BIOS prompt in less than a second and load Windows.

If you press F2 or DEL during this short period, why doesn't it let you into the BIOS? On some boards, "fast boot" causes the system to only check for a display on the first output from the GPU. If it doesn't detect a display there, it skips the BIOS prompt entirely.

To test if "fast boot" is causing your problem, plug your monitor cable into the first video output of your GPU. The first output of the GPU is usually the leftmost port (although there is a small chance that it is the rightmost port).

6. Move the GPU to the main PCIe slot

This is another potential problem if your PC has a discrete GPU. A typical ATX motherboard will provide multiple slots for peripheral hardware, and the GPU is connected via one of these PCIe slots.

A combination of the following factors can cause the BIOS prompt to not appear:

  1. You have installed your PC's graphics card in a PCIe slot other than the primary slot.
  2. You have enabled the "fast boot" setting in the BIOS.
  3. You are using a vertical GPU mount for aesthetics.

Why does the slot that the GPU is connected to matter? Some motherboards prioritize the main PCIe slot for "fast boot" and will skip the BIOS prompt if a problem is detected there.

The main PCIe slot is the highest slot when installed in a standard PC tower, usually the slot closest to the CPU:

If your PC boots to a blank screen and goes straight to Windows, try moving the GPU to the main PCIe slot. This may make the BIOS prompt appear again and respond to keyboard presses.

7. Reset BIOS to default

Now, we come to the last option: Reset BIOS settings to default.

Warning : Turn back immediately if you don't know what you're doing. You could accidentally corrupt your BIOS or make a mistake that could damage your motherboard.

Certain conditions can cause the BIOS prompt to never appear. For example:

  1. The "fast boot" setting is broken and you can't get into BIOS to turn it off
  2. System locked due to incorrect XMP configuration enabled
  3. System is unstable due to PC for faster performance or using built-in AI overclocking

In these cases, resetting the motherboard to factory defaults will restore normal access to the BIOS.

Press the Reset BIOS button

The average user probably doesn't need an expensive motherboard, but when choosing a new motherboard for their PC, there's one premium feature that's a must-have: a dedicated BIOS reset button.

This button allows you to reset the BIOS to default without having to open your computer case. If your motherboard has this button, you will find it on the back of your case.

On Asus motherboards (and many others), here's how you use the button to reset the BIOS:

  1. Turn off your computer and unplug the power cord.
  2. Hold the CLEAR CMOS button for 10 seconds and then release it.
  3. Plug the power cord back in and turn the computer back on.

If everything works, the BIOS will be reset to its default settings. A BIOS prompt will appear when you boot and you will be able to enter the BIOS by pressing the F2 or DEL key

Remove CMOS battery

Most motherboards rely on a small battery to save BIOS settings when the computer is powered off. If you are locked out because you accidentally set a BIOS password or forgot it, this method will clear the password and allow you to enter the BIOS.

When your computer is not powered on, you will want to remove your computer's CMOS battery and reinsert it. Doing so will clear your current BIOS settings and restore them to their default values.

If successful, you will receive a message on startup that the default settings have been restored. You can now press the F2 or DEL key as usual to access the BIOS.

Clear settings using Jumper pin

If none of the above options work, the last resort is to use the old-fashioned method. Moving the jumper on the motherboard's CLR_CMOS pins will clear the BIOS settings. This method is the least optimal option because it involves digging through manuals and reaching into tight spaces.

This is the usual way to do it, but you should consult your motherboard manual for details:

  1. Turn off your computer and unplug the power cord.
  2. Move the jumper over one leg. Wait 10 seconds.
  3. Move the jumper back to its original position.
  4. Plug the power back in and turn on the computer.

Hopefully one of these methods will get you back into your BIOS. If you successfully fixed the problem but then it recurs, this may be a valid reason to update your PC's BIOS to improve system stability.​​
