How to BIOS Update Motherboard

BIOS (Basic Input/Output System) is the firmware used to perform hardware initialization during the booting process of a computer. From time to time, motherboard manufacturers release BIOS updates to address issues, improve compatibility, or add features. Here’s a step-by-step guide on how to update the BIOS of a motherboard.

1. Preliminary Steps

  • Backup Important Data: Before any significant system changes, it’s always a good idea to back up essential files in case something goes wrong.
  • Check System Stability: Ensure your system is stable. If you’re experiencing crashes or other odd behaviors, it’s better to address those first.

2. Identify Your Motherboard and Current BIOS Version

  • Using System Information:
    • Type “System Information” into Windows search and open it.
    • Note down the ‘System Manufacturer’ and ‘System Model’ entries.
  • From within the BIOS/UEFI:
    • Restart your computer.
    • During boot-up, press the BIOS key (commonly F2, F10, F12, or DEL) to enter the BIOS/UEFI.
    • Look for the BIOS version/date entry.

3. Check Manufacturer’s Website for Updates

  • Go to the official website of your motherboard manufacturer (e.g., ASUS, MSI, Gigabyte).
  • Navigate to their support/download section.
  • Search for your motherboard model.
  • Look for a BIOS/UEFI download section and check if there’s a newer version than the one you have.

4. Download the Correct BIOS Update

  • Once you locate the BIOS update file, download it.
  • The update usually comes in a zip archive, which might include the BIOS file itself and an update utility.

5. Prepare the BIOS Update

There are several methods to update a BIOS:

  • Using a USB Drive:
    • Format a USB drive to FAT32.
    • Extract the BIOS update file from the archive and copy it to the USB drive.
  • Windows-based Updating Tools: Some manufacturers provide utilities that allow you to update the BIOS from within Windows.
  • Directly in the BIOS/UEFI: Some modern motherboards allow updating directly from the BIOS/UEFI interface.

6. Update the BIOS

  • Using USB Drive in BIOS/UEFI:
    • Restart your computer and enter the BIOS/UEFI.
    • Look for a BIOS update option, such as “EZ Flash,” “M-Flash,” or “Q-Flash.”
    • Select the update option, navigate to the BIOS file on your USB drive, and follow on-screen instructions.
  • Using Windows-based Tools:
    • Run the utility provided by your motherboard manufacturer.
    • It will guide you through the update process.

7. Post-Update Steps

  • After the update is complete, your computer will reboot.
  • Enter the BIOS/UEFI to confirm the new version.
  • It’s recommended to load the default settings after the update and then reconfigure any custom settings you had before.


Updating the BIOS can bring stability, compatibility, and new features. However, it’s crucial to approach this process with caution. A failed BIOS update can render your motherboard unbootable. Always ensure you’re using the correct BIOS file for your motherboard model, avoid updating during power fluctuations, and never interrupt the update process.
