How to Change BIOS Settings in Windows 11

by

When it comes to optimizing your computer’s performance, you might often hear the term “BIOS” (Basic Input/Output System). The BIOS is a critical component of your computer’s firmware, allowing it to boot up and manage hardware communication before the operating system takes control. As Windows 11 users, you may find the need to change BIOS settings to improve security, enhance performance, or enable specific hardware features. This article will guide you through the various aspects of changing BIOS settings on a Windows 11 system, from understanding what BIOS is to executing changes safely.

Understanding BIOS

The BIOS is software stored on a small memory chip on the motherboard that takes charge as soon as the computer is powered on. It performs basic functions such as hardware initialization and power-on self-test (POST). Without the BIOS, your computer would not be able to load the operating system.

While many of us refer to it simply as “BIOS,” different types of firmware can exist. Here are the two most commonly referred to:


Legacy BIOS

: This is the traditional BIOS that has been around for many years. It uses the MBR (Master Boot Record) partitioning scheme and is limited to booting from drives no larger than 2 TB.


UEFI (Unified Extensible Firmware Interface)

: This is the modern replacement for older BIOS systems. It supports larger drives (over 2 TB), faster boot times, and graphical user interfaces. Most Windows 11 systems come with UEFI.

There can be various reasons to modify BIOS settings, including:


  • Hardware Compatibility

    : Certain peripherals or components may require you to tweak settings.

  • Performance Optimization

    : Overclocking your CPU or RAM can significantly boost performance.

  • Security Features

    : Enabling Secure Boot or TPM (Trusted Platform Module) can enhance system security.

  • Boot Order

    : Changing the sequence helps if you plan to boot from an external device or a different disk.

Accessing the BIOS in Windows 11

Before you can make any changes to the BIOS settings, you need to know how to access it. The process for entering BIOS differs from one manufacturer to another, but generally, you will need to follow these steps:


Open Settings

: Click on the Start button and select Settings. Alternatively, you can press

Windows + I

on your keyboard.


System Recovery

: Navigate to “System” and then select “Recovery.”


Restart in Advanced Startup

: Under the Advanced Startup section, click on “Restart now.” Your computer will restart and present you with several options.


Navigate through Options

: Choose “Troubleshoot,” then “Advanced Options,” then “UEFI Firmware Settings” (if available), and finally click “Restart.”

Your computer will reboot and take you directly to BIOS or UEFI settings.

Another way to access the BIOS is to use specific keyboard shortcuts when your computer boots up. The timing varies depending on the manufacturer:


  • Acer

    : Press

    F2

    or

    Del

  • Asus

    : Press

    F2

    or

    Del

  • Dell

    : Press

    F2

  • HP

    : Press

    Esc

    and then

    F10

  • Lenovo

    : Press

    F1

    or

    F2

  • MSI

    : Press

    Delete

  • Toshiba

    : Press

    F2

If you are unsure, check your computer’s manual or the manufacturer’s website.

Navigating the BIOS Interface

Once you’re in the BIOS interface, the layout will depend on your specific hardware. However, some general elements are quite common:


  • Main Tab

    : Displays system information, such as the date and time, and the hardware installed.

  • Advanced Tab

    : This is where you may find options for CPU, SATA configuration, and virtualization features.

  • Boot Tab

    : Allows you to change the boot order of your drives.

  • Security Tab

    : Contains settings for passwords, TPM, and Secure Boot options.

Changing Specific BIOS Settings

Now that you’ve accessed the BIOS, you may want to make some specific changes. Below are some common adjustments:

You may need to change the order of your boot devices if you want the computer to boot from USB drives, external HDDs, or other devices before the internal HDD/SSD.

  • Navigate to the Boot tab.
  • Use the arrow keys to select the device you want to prioritize.
  • Follow the on-screen instructions to change its order by moving it up or down the list.

Secure Boot is a security standard that ensures your PC only boots using firmware that is trusted by the manufacturer.

  • Go to the Security tab.
  • Locate the Secure Boot option and enable it.

Make sure your operating system supports secure boot, as turning it on with an incompatible OS can cause boot failures.

If you plan to run virtual machines (VMs) using software such as Hyper-V or VMWare, you need to enable virtualization technology (Intel VT-x or AMD-V).

  • Navigate to the Advanced tab.
  • Locate the virtualization options, usually under CPU Configuration, and enable them.

If you are looking to boost performance, especially for gaming or high-performance tasks, overclocking the CPU or RAM may be an option.

  • Find the CPU Configuration options in the Advanced tab.
  • Carefully adjust the CPU multiplier and voltage settings. Monitor the temperatures and stability of your system after any change.

To enhance security, you can place a password on your BIOS settings.

  • Go to the Security tab.
  • Follow the prompts to set an Administrator password, as well as a user password if necessary.

Saving Changes and Exiting BIOS

After making the desired changes, you need to save those adjustments before exiting. To do that:

  • Press

    F10

    (or follow your BIOS’s specific guideline).
  • Confirm any prompts to save changes.
  • Your system will restart, implementing the changes you made.

Common Issues and Troubleshooting

After changing BIOS settings, you might run into issues like boot failures or instability. Here are some common fixes:

Conclusion

Changing BIOS settings can be an important step in optimizing your Windows 11 system. Whether you’re looking to increase performance, improve security, or simply manage hardware features, knowing how to safely access and navigate the BIOS interface is essential. While the process might seem daunting at first, a careful approach and awareness of your system specifications can empower you to make impactful changes. Always remember to document any changes you make, so you can revert them if needed, and don’t hesitate to consult your motherboard’s manual for specific instructions related to your model. With time, changing BIOS settings will become a routine task for enhancing your Windows 11 experience.
