Updating your BIOS can be beneficial but isn’t always required. This delicate process can provide security enhancements, new functionalities, support for advanced processors, and solutions to underlying system issues. It is considered a final approach to tackling stubborn problems that persist despite OS reinstallation or component replacement.

Preparation for Update

First, ensure that your system supports UEFI firmware updates. This is usually the case for systems running Windows 8 or later, including all desktop editions of Windows 10. Before initiating the update, verify your BIOS version to check if an update is indeed necessary.

Updating Your BIOS

  1. Use the Command Prompt to determine your motherboard model.
  2. Check your current BIOS version and visit the manufacturer’s website for any available updates.
  3. Download and unpack the BIOS update files into a desktop folder. You should find two key files: an .exe and a .cap file.
  4. Ensure a constant power supply to avoid potential disruptions during the update, as any interruption could leave your PC inoperable.
  5. Move the BIOS files to a USB drive.
  6. With the USB drive inserted, restart your computer, boot into your BIOS, and commence the BIOS update. Make certain your system maintains power throughout this process.

Upon completing the update, which may involve several restarts, you can verify the BIOS version using the Command Prompt.

Accessing UEFI BIOS in Windows

If you need to change the UEFI BIOS settings, access the motherboard firmware by going to Settings in Windows 10, clicking on “Update & Security,” then “Recovery,” and then “Restart now” under the Advanced startup section. Your computer will restart following by the “Choose an option” screen. Click on “Troubleshoot,” then “Advanced option,” and finally “UEFI Firmware Settings.” Restart your PC to save changes.

Expert Tip: For smoother PC performance, consider using a PC optimization tool. It handles junk files, incorrect settings, and harmful apps. Make sure it's right for your system, and always check the EULA and Privacy Policy.

Note of Caution

The BIOS update involves some risk and should be performed with caution. Wrong firmware settings can prevent your computer from starting correctly. If you’re unsure or uncomfortable with the process, it’s best to seek professional help.

To switch from legacy BIOS to UEFI in Windows 10, use the ‘MBR2GPT’ tool. Ensure your device supports UEFI firmware settings before attempting to convert, as failing to adhere to prerequisites can lead to system errors or hardware failure.

In summary, while updating or switching your BIOS can offer benefits such as improved stability and new feature support, it requires careful handling. Consider creating a backup of your current BIOS before initiating the process.
