Important Before You Start

BIOS updates should be done carefully. Always download the correct BIOS file for your exact motherboard model and revision.

Flashing the wrong BIOS file can stop your motherboard from working correctly.

If you are updating your CPU, make sure you update the BIOS with your existing working CPU installed first, unless your motherboard specifically supports BIOS Flashback without a CPU.

Why You Might Need A BIOS USB

A BIOS USB drive is used to hold the BIOS update file for your motherboard. You may need this when flashing or updating the BIOS through the motherboard BIOS menu, a built in flash tool, or BIOS Flashback on supported boards.

This can be useful for CPU upgrades, Windows 11 compatibility, TPM issues, Secure Boot errors, hardware detection problems, stability improvements or manufacturer recommended BIOS updates.

When A BIOS Update May Be Needed

You are upgrading to a newer CPU
Your motherboard does not currently support the new CPU
You are getting TPM errors in Windows 11
You are getting Secure Boot errors in Windows 11
A game or anti cheat system is failing a Windows 11 security check
The motherboard manufacturer recommends a BIOS update
You are troubleshooting stability or hardware detection issues

CPU Upgrade Warning

If you are updating your CPU, flash the BIOS first with your existing working CPU still installed.

If you remove the old CPU and install a newer CPU before updating the BIOS, the PC may not boot if the motherboard does not already support that CPU.

The exception is if your motherboard supports BIOS Flashback without a CPU, but you should check your exact motherboard manual before relying on this.

Step By Step Guide

Step 1: Find Your Exact Motherboard Model

Before downloading anything, confirm the exact motherboard model. If the board has a revision number, check that too. Some manufacturers have different BIOS files for different revisions of the same model.

Step 2: Go To The Official Manufacturer Website

Use the official support page for your motherboard brand. Search for your exact motherboard model and open the support or downloads section.

Step 3: Download The Correct BIOS File

Download the BIOS file that matches your exact motherboard model. Read the notes carefully, especially if the manufacturer gives warnings about update order, CPU support or bridge BIOS versions.

Step 4: Prepare A USB Drive

Use a small USB drive where possible. Format the USB drive as FAT32 unless your motherboard manual says otherwise. Formatting the USB drive will erase the files currently on it.

Step 5: Extract The BIOS File

Most BIOS downloads come as a compressed zip file. Extract the folder first, then copy the actual BIOS file to the USB drive.

Step 6: Check If The File Needs Renaming

Some motherboards need the BIOS file to be renamed, especially when using BIOS Flashback. Check the motherboard manual or manufacturer instructions for the correct file name.

Step 7: Copy The BIOS File To The USB

Copy the required BIOS file to the USB drive. For some boards, the file may need to be placed in the main root area of the USB drive rather than inside a folder.

Step 8: Safely Eject The USB Drive

Once the file has copied, safely eject the USB drive. It should now be ready to use for the BIOS update process.

BIOS Update Safety Checklist

Use the correct BIOS file for your exact motherboard model
Check the motherboard revision if applicable
Read the BIOS notes before updating
Use a stable power source
Do not turn the PC off during a BIOS update
Do not remove the USB drive during the update
Do not flash during a power cut or unstable power situation
Do not guess if you are unsure

Do Not Use Random BIOS Files

Only use BIOS files from the official motherboard manufacturer website.

Do not use BIOS files from random forums, file sharing sites, social media posts or unknown downloads. Even if the file name looks correct, it may not be safe or suitable for your exact motherboard.

What Happens Next?

Once the BIOS USB has been created, the next step is to follow your motherboard’s BIOS update method. This might be called M Flash, EZ Flash, Instant Flash, Q Flash, BIOS Flashback or something similar depending on the motherboard brand.

Always follow the instructions for your exact motherboard model before starting the BIOS update.
