How to Install a BIOS Update on Your Gigabyte Motherboard

What you need before you start

A BIOS update on a Gigabyte motherboard requires three things: the correct update file for your exact motherboard model, a USB drive formatted to FAT32, and a working computer that can boot. Do not attempt a BIOS update if your power supply is unstable, your computer randomly restarts, or you are not certain of your motherboard model number.

Find your motherboard model by opening Device Manager on Windows (right-click the Start button, select Device Manager, expand "System devices"), or by physically looking at the board if your case is open. The model number is printed on the board itself — it looks like "B650E-E" or "Z790-UD". Write this down exactly as it appears.

Go to the Gigabyte support website, enter your motherboard model in the search box, and download the latest BIOS file from the Downloads section. The file will be a .bin or .exe file. Save it to your desktop so you can find it easily.

Key Takeaways

Find your exact motherboard model number before downloading anything — it is printed on the board and must match the BIOS file exactly.
Format a USB drive to FAT32, copy the BIOS file to the root of the drive, and restart your computer into the BIOS menu by pressing Delete or F2 during startup.
Use the Q-Flash tool inside the BIOS menu to select your USB drive and begin the update — the process takes 2 to 5 minutes and your computer will restart automatically when finished.
Do not turn off your computer, unplug the power cable, or remove the USB drive while the update is running, or your motherboard may become unusable.

Format your USB drive and copy the BIOS file

Plug a USB drive into your computer. The drive should be at least 1 GB, though 4 GB or larger is safer. Open File Explorer, right-click the USB drive, and select Format. In the dialog that appears, set the file system to FAT32, give it any name you want, and click Start. This erases everything on the drive, so move any files you need to keep first.

Once the format is complete, copy the BIOS file you downloaded to the root of the USB drive — not into a folder, but directly on the drive itself. You should see the .bin or .exe file sitting at the top level when you open the drive in File Explorer. Safely eject the USB drive by right-clicking it and selecting Eject.

Enter the BIOS menu and locate Q-Flash

Plug the USB drive into a USB port on the back of your computer (the rear ports are more reliable than front headers). Restart your computer completely. As soon as you see the motherboard logo or the first startup screen, press Delete or F2 repeatedly — do not wait for Windows to load. You should enter the BIOS menu within a few seconds.

The BIOS menu looks like a blue or gray screen with white text and rows of options. Look for a tool called Q-Flash, Q-Flash Plus, or M-Flash depending on your motherboard generation. This is usually in the main menu or under a Tools tab. Click on it or press Enter to open it.

Select your USB drive and start the update

Q-Flash will scan for USB drives and show you a list. Select the drive that contains your BIOS file — it should show the drive name and size. Press Enter. The tool will then show you the BIOS files it found on that drive. Select the .bin file (or the file name that matches your motherboard model) and press Enter again.

A confirmation dialog will appear asking if you want to update the BIOS. Read it carefully — it will tell you the current BIOS version and the new version you are about to install. Press Y or click Yes to begin. The update will start immediately. You will see a progress bar that fills from 0% to 100%. This takes 2 to 5 minutes depending on your motherboard.

Do not touch the computer, do not unplug the power cable, and do not remove the USB drive while the progress bar is moving. If the power cuts out during an update, your motherboard may not boot again and will require professional repair or replacement.

What happens after the update finishes

When the progress bar reaches 100%, the computer will restart automatically. You will see the BIOS menu again briefly, then the computer will boot into Windows normally. This is correct behavior. The update is complete.

Once Windows has loaded, you can remove the USB drive. You do not need to do anything else — the new BIOS is now installed and active. If you want to confirm the update worked, restart the computer, enter the BIOS menu again, and look for the BIOS version number. It should match the version number of the file you installed.

Troubleshooting if something goes wrong

If Q-Flash does not find your USB drive, the drive may not be formatted correctly or the BIOS file may be in a folder instead of at the root. Eject the drive, format it again to FAT32, copy the BIOS file directly to the root (not in a folder), and try again. Try a different USB port on the back of the motherboard if the first one does not work.

If you cannot enter the BIOS menu, you may be pressing the wrong key. Different Gigabyte boards use Delete, F2, or F12. Restart the computer and try each key in turn as soon as you see the motherboard logo. If none of these work, consult your motherboard manual — it will list the correct key on the first page.

If the computer will not boot after the update, the update may have been interrupted by a power loss. This is a serious problem that usually requires a professional to repair. To prevent this, make sure your power supply is working correctly and consider using an uninterruptible power supply (UPS) if your electricity is unreliable.

When to update and when to skip it

BIOS updates fix bugs, improve stability, and add support for new processors. You should update if Gigabyte has released a fix for a specific problem you are experiencing, if you are installing a new processor that requires a newer BIOS, or if the release notes mention stability improvements for your hardware. You do not need to update just because a new version exists.

Do not update if your computer is working normally and you have no reason to change anything. A BIOS update carries a small risk of something going wrong, so only do it when there is a real benefit. If your computer is unstable or crashes frequently, a BIOS update might help, but it is not a may provide fix — test other things first, like your RAM and storage drive.

Frequently Asked Questions

Can I update the BIOS from Windows instead of from the BIOS menu?

Some Gigabyte motherboards include a Windows utility called @BIOS that can update the BIOS without restarting. This is convenient but riskier — if Windows crashes or your power cuts out during the update, the BIOS can be corrupted. The Q-Flash method from the BIOS menu is safer because it does not depend on Windows running correctly.

What if I update to the wrong BIOS file by mistake?

If you installed a BIOS file for a different motherboard model, your computer will not boot. You will need to use a recovery method called BIOS Flashback or Q-Flash Plus, which requires a second USB drive and the correct BIOS file. Consult your motherboard manual for the exact steps, as the process varies by model. This is why confirming your motherboard model before downloading is critical.

How long does a BIOS update take?

The actual update process takes 2 to 5 minutes from the moment you press Yes in Q-Flash until the computer restarts. The entire process, including entering the BIOS menu and selecting the file, usually takes 10 to 15 minutes. Do not interrupt it or turn off the computer during this time.

Do I need to clear CMOS or reset the BIOS after updating?

No. A BIOS update preserves your current settings — your overclocks, boot order, and other customizations will remain. You only need to clear CMOS if the computer will not boot after the update, which is rare. If that happens, consult your motherboard manual for the CMOS battery location and remove it for 30 seconds.

Can I update the BIOS if my computer is overclocked?

Yes, but restart the computer and reset the BIOS to default settings before updating. Overclocked settings can sometimes interfere with the update process. Once the update is complete and the computer boots normally, you can re-apply your overclocking settings if you want.
