The Basic Input/Output System (BIOS) is a crucial component of your computer, serving as the bridge between the computer’s hardware and operating system. Updating the BIOS settings can help enhance system performance, compatibility, and security. Here’s a comprehensive guide on how to navigate and update your BIOS settings safely and effectively.

Understanding the Importance of BIOS

BIOS is fundamental software stored on a small memory chip on the motherboard. It performs the initial hardware checks and loads the operating system. An updated BIOS can resolve hardware compatibility issues, support new types of hardware, and improve system stability and performance.

Pre-update Precautions

Before embarking on the update journey, it’s essential to take some precautions. Ensure that your computer is connected to a stable power source to avoid interruptions during the update process, as it can render your system inoperable. It’s also critical to back up important data to prevent any potential loss.

Identifying the Current BIOS Version

Before updating, you need to know the existing BIOS version. Access the system information by pressing the Windows key + R, typing “msinfo32,” and pressing Enter. Here, you can find the BIOS version/date information.

Finding the Right Update

Once you know your BIOS version, visit the motherboard manufacturer’s official website to find the appropriate update. Enter the model number of your motherboard, and download the latest BIOS update available, ensuring it’s compatible with your system.

Preparing the USB Drive

Most modern motherboards support BIOS updates through a USB drive. Format a USB drive to FAT32 and copy the downloaded BIOS update file to it. Make sure the USB drive has no other files, avoiding any confusion during the update process.

Accessing the BIOS Setup

Restart your computer and press the required key (usually Esc, Del, or F2) during the startup to enter the BIOS setup. Navigate using the arrow keys, as the mouse usually doesn’t work in BIOS.

Updating the BIOS

Within the BIOS setup, find the option for updating/flashing the BIOS, usually located under the “Advanced,” “Tool,” or “Exit” menu. Select the update option and choose the update file from your USB drive. Confirm the update and let the system handle the rest. Avoid interrupting the process under any circumstances.

Configuring the Updated BIOS

After a successful update, the system will reboot. Enter the BIOS setup again to configure the updated settings. Load the optimized/default settings and adjust them according to your preference and hardware configuration, such as boot order and device priorities.

Verifying the Update

Once the settings are configured, boot into your operating system and verify the update by checking the BIOS version/date in the system information again. This step ensures that the update was successful and is functioning as intended.


Updating your BIOS settings can seem daunting, but it’s a manageable task when approached with caution and understanding. The process is crucial for maintaining system stability and compatibility, making it an essential aspect of computer maintenance. By following the outlined steps carefully, you can ensure a smooth and safe update experience, optimizing your system for peak performance.


  1. What is BIOS, and why is it important to update it? BIOS is a fundamental software that initializes the hardware when a computer is turned on. Updating it can improve system performance, compatibility, and security.
  2. Is it risky to update the BIOS settings? Updating BIOS does come with some risk, such as potential system failure if interrupted. However, careful adherence to instructions can mitigate these risks.
  3. How can I find my current BIOS version? You can find your current BIOS version by accessing the system information through the “msinfo32” command in the Run dialog.
  4. Can I use any USB drive to update the BIOS? Yes, but it should be formatted to FAT32, and it’s recommended to have only the BIOS update file on it during the update process.
  5. Do I need to adjust settings after updating the BIOS? Yes, it’s crucial to configure the BIOS settings after an update, including loading the optimized/default settings and adjusting them according to your hardware configuration and preferences.
