The booting and starting of a computer is an operation on its own. The computer being made up of both hardware and software, has to combine both operations to give the user a piece of information. Setting these up happens during booting, as this prepares both input and output devices for usage. The Basic Input/Output System otherwise known as BIOS or UEFI, when open, plays a critical role in the initial startup process of a computer, helping to establish communication between the hardware components and the operating system.

What is BIOS and what does it do?

The firmware known as the BIOS, which is integrated into the motherboard of computers, is in charge of loading the operating system, initializing hardware components, and enabling low-level system interactions.

The BIOS conducts several operations during the boot process, including testing the functionality of hardware elements such as the CPU, RAM, hard drives, and other peripherals. The operating system can be loaded into the computer’s memory to further assist. Modern computers typically replace the BIOS with UEFI (Unified Extensible Firmware Interface). They provide improved compatibility and more sophisticated functionality. So, how do you access the BIOS/UEFI on a computer laptop or desktop running on Windows 11? Here are the detailed steps to it;

1. Utilizing Settings

  • Click on the “Start” button (Windows icon) in the taskbar.
  • Select the “Settings” gear icon, which looks like a little gear.
  • In the Settings window, click on “System.”
  • Scroll down and choose “Advanced startup.”
  • Click on the “Restart now” button.
  • When your computer restarts, you’ll see a blue screen. Click on “Troubleshoot.”
  • Next, choose “Advanced options” and then “UEFI Firmware Settings.”
  • Click on “Restart,” and your computer will boot into the BIOS.

2. Applying the Shutdown Menu

  • Click on the “Start” button.
  • Press and hold the “Shift” key on your keyboard.
  • While holding “Shift,” click on the “Power” button, then select “Restart.”
  • Your computer will restart and display the blue screen.
  • Follow the same steps as mentioned in the “Using Settings” section to access the BIOS.

3. Keyboard shortcut usage

  • Switch off your computer.
  • During startup, keep pressing the BIOS access key. Some frequently used keys include “F2,” “F10,” “Delete,” and “Esc.”
  • When the appropriate key is pushed, the BIOS interface will be shown.

4. Using Command Prompt

  •     The “Windows” key should be pressed, then “cmd.”
  •     Click “Command Prompt” with the right mouse button, then select “Run as administrator.”
  •     Enter “shutdown /r /fw” into the Command Prompt box.
  •     The UEFI (BIOS) settings will be loaded when your machine restarts.

5. Using the Shift + Restart Key

  • Select “Start” from the menu.
  • On your keyboard, hold down the “Shift” key while pressing.
  • From the Start menu, select “Restart”.
  • Follow the previously mentioned “Troubleshoot,” “Advanced options,” and “UEFI Firmware Settings” procedures.

What Computer Problems does BIOS help Diagnose

Although the BIOS doesn’t directly solve issues, it does offer necessary capabilities that can help in identifying and fixing a variety of hardware-related problems. The BIOS may assist in troubleshooting several common computer issues, such as:

How to Enter or Open BIOS in Windows 11

1. Startup Problems

The BIOS comes to your aid when your computer refuses to boot up normally. It is comparable to a backstage manager inspecting each performer before a performance. The BIOS ensures that every component is functioning properly, from the CPU (the brain) through the memory and storage. The BIOS warns you if something is off so you can make the necessary corrections before the main act starts. It makes sure everything is in place for a smooth start, much like a safety net.

2. Overheating

Using the BIOS to address overheating issues involves adjusting settings related to system temperature and cooling. Here’s a step-by-step guide:

1. Start your computer again, To access the BIOS during startup, repeatedly hit the designated key (such as “F2,” “F10,” “Delete,” or “Esc”).

2. In the BIOS, search for the “Hardware Monitor,” “Advanced,” or “Power Management” sections.

3. Increase fan speeds for improved cooling by finding the “Fan Control,” “Fan Profile,” or “Fan Curve” options. To activate fans at lower temperatures, see the temperature threshold settings.

4. Choose an aggressive cooling policy if one is offered when optimizing cooling policies. Exit BIOS after saving modifications (often by pressing “F10”).

5. Use software sensors or BIOS measurements to keep an eye on the room temperature.

3. Forgotten Password

You may use the BIOS to help you reset your code so you can log back into your computer. To accomplish this, follow these steps:

1. Restart your computer and click the key (often “Delete,” “F2,” “F10,” or “Esc”) listed on the screen to access the BIOS configuration.

Using the arrow keys, move to the “Security” or “Password” area of the BIOS after entering it.

3. Depending on the version of your BIOS, you can see options like “User Password” or “Supervisor Password.” Choose the password that you wish to change.

4. Decide whether to reset or modify the password. Before you may change your password, some BIOS versions can ask you for your current password.

5. Save your modifications and quit the BIOS. Rebooting your computer is required.

6. Attempt logging in without a password or using the new password you specified in the BIOS once the system has restarted.

4. Hardware Integration

The integration of new hardware components, such as an improved graphics card or more memory, necessitates the successful cooperation of both old and new elements. The BIOS, which acts as a mediator to guarantee efficient communication and integration between the various hardware components, is crucial in supporting this collaboration.


How do I open BIOS on a Windows 11 laptop?

To open the BIOS on a Windows 11 laptop, restart your laptop and press the BIOS access key repeatedly while it’s booting up. The key might be different for each laptop model, so refer to your laptop’s manual or look for on-screen prompts during startup.

How can I find the BIOS access key for my specific computer model?

You can usually find the BIOS access key for your computer model in the user manual that came with your computer. Alternatively, you can search online using your computer’s make and model to find the specific key required to enter the BIOS.

Can I access the BIOS from within Windows 11?

No, the BIOS cannot be accessed directly from within Windows 11. You need to restart your computer and press the appropriate BIOS access key during startup to enter the BIOS interface.


In conclusion, understanding how to access and utilize the BIOS/UEFI in Windows 11 is essential for ensuring proper computer functionality. The BIOS serves as firmware that initializes hardware components, loads the OS, and conducts crucial hardware tests during boot-up. Various methods, including settings, shortcuts, and command prompts, allow users to access the BIOS. It aids in diagnosing and addressing common computer problems such as startup issues, overheating, forgotten passwords, and hardware integration. By effectively utilizing the BIOS, users can optimize their computer’s performance and troubleshoot various hardware-related concerns.
