MSI BIOS Update Methods (2026 Recommended)

There are three main ways to update the BIOS on an MSI motherboard, but the M-Flash method is considered the safest and most reliable. Below is a fully explained version of how it works and why it is recommended.

M-Flash Method (Most Safe and Recommended)

M-Flash is MSI’s built-in BIOS flashing tool that runs directly inside the BIOS environment.
This means you don’t need Windows, reducing the risk of crashes, power issues, or software conflicts during the update.

How the M-Flash Method Works (Step-by-Step):

Step 1: Download the Correct BIOS File

Go to the official MSI website, search for your exact motherboard model, and download the latest BIOS update available.

Step 2: Prepare a USB Drive (FAT32 Format)

Format a USB drive to FAT32 and copy the downloaded BIOS file onto it.
No folders are needed — keep the file in the root directory for easier detection.

Step 3: Enter the BIOS Setup

Restart your PC and repeatedly press DEL to enter the BIOS menu.
Once inside, confirm your current BIOS version if needed.

Step 4: Select the M-Flash Option

Inside the BIOS, look for the M-Flash section (usually located on the left side or bottom).
Click it, and the system will restart and automatically switch into flashing mode.

Step 5: Choose the BIOS File from the USB

When M-Flash loads, it will show the files on your USB drive.
Select the BIOS update file you copied earlier and confirm the update.

Step 6: Wait for the Update to Complete

The flashing process usually takes 5–10 minutes.
Do not turn off your PC or remove the USB drive during this time.

Once finished, your PC will automatically reboot with the updated BIOS version.

Why M-Flash Is Recommended

  • Extremely safe since it runs outside Windows
  • Simple and beginner-friendly
  • No risk of Windows crashing during update
  • Ensures clean flashing environment with minimal errors

BIOS Flashback (For Recovery When an Update Fails)

BIOS Flashback is a special recovery feature available on many mid-range and high-end MSI motherboards.
It’s designed for situations where your system cannot boot or the BIOS becomes corrupted after a failed update.
Unlike other methods, BIOS Flashback lets you update the BIOS without turning on the PC or entering the BIOS interface.

When Should You Use BIOS Flashback?

You should use this method if:

  • Your PC is not booting at all
    (black screen, no display)
  • The BIOS has become corrupted
    (due to a failed or interrupted update)
  • You installed the wrong BIOS version by mistake
  • The motherboard is new and doesn’t support your CPU yet

In all these cases, BIOS Flashback helps recover your system easily.

How to Use BIOS Flashback (Step-by-Step Guide)

Step 1: Prepare the BIOS File

  • Download the correct BIOS update for your motherboard from MSI’s official website.
  • Extract the file and rename it exactly as instructed on the MSI download page.
    (Each motherboard model requires a specific file name.)
  • Copy the renamed BIOS file to a FAT32-formatted USB drive.

Step 2: Locate the Flashback USB Port

On the back of your motherboard’s I/O panel, you will find a USB port labeled “Flashback” or “BIOS Flashback”.
This port is specially designed for the recovery process.

Step 3: Plug in the USB Drive

Insert your USB drive (with the BIOS file) into the Flashback USB port.

Step 4: Press the Flashback Button

Near the USB port, you’ll find a small Flashback button.
Press and hold it for a few seconds until the Flashback LED starts blinking.

Step 5: Wait for the LED to Stop Blinking

The LED light will blink during the update process.
Do not remove the USB drive or cut power.

Once the LED stops blinking, the BIOS has been successfully restored.

Why BIOS Flashback Is So Useful

  • You don’t need the PC to boot
  • You don’t need a CPU, RAM, or GPU installed
  • It is the safest recovery method for a dead or corrupted system
  • Perfect for rescuing motherboards after a failed update

MSI Live Update (Windows Application)

MSI Live Update is a Windows-based utility that allows users to update drivers, utilities, and even the BIOS directly from the desktop.
This method is very convenient because it doesn’t require entering the BIOS or preparing a USB drive. However, it comes with higher risk because the update runs inside Windows, where crashes or interruptions can corrupt the BIOS.

How to Update BIOS Using MSI Live Update (Step-by-Step)

Step 1: Install MSI Live Update

Download the official MSI Live Update tool from MSI's website and install it on your Windows PC.

Step 2: Launch the Application and Scan

Open the software and click the “Scan” button.
The tool will automatically check for available updates, including BIOS, drivers, and utilities.

Step 3: Select the BIOS Update

If a new BIOS version is available, it will appear in the list of updates.
Select the BIOS update option.

Step 4: Apply the Update

Click “Download and Install” to start the update process.
Your system may restart automatically to complete the flashing.

Important Caution

This method is easy, but riskier than M-Flash or BIOS Flashback because:

  • If Windows freezes, crashes, or loses power during the update, the BIOS can become corrupted.
  • System background apps or unstable drivers can interfere with flashing.
  • Not recommended for beginners or for systems with unstable Windows environments.

Who Should Use MSI Live Update?

  • Users who are confident with Windows-based tools
  • Systems that are fully stable and free from software issues
  • Those who want a quick method and understand the risks

Important Safety Tips (Avoid Update Failures)

These precautions are not MSI-specific. If firmware flashing makes you nervous in general, our plain-language explainer on why BIOS updates go wrong covers ASUS, Gigabyte and Lenovo boards too, and the vendor-neutral guide to eight BIOS update methods is the general version of this page.

Before performing an MSI BIOS update, it’s important to follow a few safety precautions to ensure the process completes successfully and without errors. A BIOS update is safe when done correctly, but even a small interruption can cause major issues.

1. Ensure Stable Power or Use a UPS

A power cut during a BIOS update can corrupt the firmware and make your motherboard unbootable.
Using a UPS — or updating only when power is stable — greatly reduces this risk.

2. Use a FAT32-Formatted USB Drive

For methods like M-Flash or BIOS Flashback, MSI motherboards read BIOS files best when the USB drive is formatted to FAT32.
Using another format may prevent the BIOS from detecting the file.

3. Never Turn Off the PC During the Update

Once the update begins, do not restart or shut down your system.
Interruptions can corrupt the BIOS and require recovery via BIOS Flashback or professional service.

4. BIOS Settings May Reset After Update

After updating, the BIOS may automatically reset to default values.
If you previously overclocked your CPU, GPU, or RAM:

  • XMP/EXPO profiles may need to be re-enabled
  • Custom fan curves or voltages may need to be set again

  • Some methods may be technical for beginners
    Processes like M-Flash or Flashback may feel complicated for users who are new to BIOS-related tasks.

MSI Center Method (Update BIOS Without a USB Drive)

If you would rather not touch a USB stick at all, this is the method you want. MSI Center is MSI's current Windows application and it has replaced the older MSI Live Update utility on most modern boards. It fetches and applies the BIOS from inside Windows, so there is no formatting and no file copying.

How to update MSI BIOS using MSI Center

Step 1: Install MSI Center from the official MSI site or the Microsoft Store.

Step 2: Open it and go to Support → Live Update.

Step 3: Click Scan. MSI Center lists the driver and BIOS updates matching your exact board.

Step 4: Tick only the BIOS entry, click Install, and let the machine reboot on its own. The flash happens during that restart.

Step 5: Once Windows is back, press Delete at the next startup and confirm the version on the BIOS main screen.

The honest caveat: this is the most convenient method and the least robust one. It depends on Windows staying stable for the whole flash. A driver crash, a Windows update starting in the background, or a power cut is far more dangerous here than with M-Flash, which runs before Windows exists. Use MSI Center when convenience matters, M-Flash when the update matters.

Which MSI BIOS Version Should You Install?

Most guides say install the latest. That is not always right, and choosing wrong is a common reason an update causes more problems than it solves.

Install the newest version when you are fitting a CPU the board does not detect, your exact fault is named in the release notes, there is a published security or microcode fix, or your memory will not run at its rated XMP/EXPO speed.

Stay where you are when the machine is stable and nothing in the changelog applies to you. A BIOS update is not routine maintenance like a Windows update. There is no prize for running the newest firmware.

Read the release notes on your board's own download page. Entries are cumulative, so the newest file already contains every fix below it — you never need to flash intermediate versions one at a time.

Check for one-way updates. Some AGESA and Intel ME releases cannot be rolled back, and MSI flags this on the download page. If a version says downgrade is unsupported, treat that flash as permanent.

What to Do If the MSI BIOS Update Fails

This is the part most step-by-step guides skip, and the only part that matters when something goes wrong.

Black screen, no POST. Do not keep power-cycling. If the board has a BIOS Flashback button, use the Flashback procedure above — it works with no CPU, no RAM and no GPU fitted, which is precisely why the feature exists.

No Flashback button. Clear CMOS first: switch off at the wall and pull the CR2032 battery for about five minutes, or move the JBAT1 jumper to clear. Plenty of "failed" updates are a corrupted settings block rather than a corrupted BIOS.

It updated but the PC feels worse. Load optimised defaults before assuming the flash broke something. A BIOS update wipes your settings, so XMP, boot order and fan curves are gone — and a system running memory at base speed off the wrong boot device genuinely does feel broken.

It boots but the version did not change. The file was for a different board revision, or it was not in the root of the USB drive. Check the exact model and revision printed on the board, not just the model name.

The recovery logic is not MSI-specific. Our walkthrough of an HP BIOS update failing with an unreadable image file covers the same class of fault, and the B07 firmware update guide deals with boot and TPM errors that show up after a flash.

How to Enter the MSI BIOS

The MSI BIOS key is Delete. Tap it repeatedly the moment the machine powers on, before the Windows logo appears. Some MSI laptops use F2.

If the splash screen goes by too fast to catch — normal with an NVMe drive and Fast Boot on — go through Windows instead: hold Shift while clicking Restart, then Troubleshoot → Advanced options → UEFI Firmware Settings. That drops you straight into the BIOS with no key timing at all. There is more background in our guide to what BIOS is and how to access it on Windows PCs, and if you are unsure whether your system is UEFI or legacy, how to check UEFI mode in Windows answers that in a minute.

Conclusion

In 2026, MSI has made the BIOS update process smoother, safer, and more efficient than ever—especially with reliable tools like M-Flash and BIOS Flashback.
As long as you follow the recommended safety steps and choose the correct update method, the process is quick and risk-free.
A successful BIOS update can significantly improve your system’s performance, stability, hardware compatibility, and overall lifespan.

Frequently Asked Questions

Is a BIOS update necessary?

If your PC is working perfectly, a BIOS update isn’t mandatory.
However, it becomes important when you need support for new CPUs, RAM modules, or stability fixes.

How long does an MSI BIOS update take?

A typical BIOS update takes around 5–10 minutes, depending on the motherboard and update method.

What should I do if the update fails?

If your MSI motherboard includes BIOS Flashback, you can easily recover the system by reinstalling the BIOS using a USB drive—no booting required.

Does updating the BIOS delete my data?

No. BIOS updates do not affect your Windows installation or personal files.
Only BIOS settings may reset to default values.

Can I update MSI BIOS without a USB drive?

Yes. Use MSI Center’s Live Update from inside Windows — it downloads and flashes the BIOS with no USB stick involved. It is the most convenient route, but because the flash happens while Windows is running, M-Flash from a USB drive stays the safer choice for an update you cannot afford to lose.

What is the MSI BIOS key?

Press Delete repeatedly as soon as the PC powers on; some MSI laptops use F2. If the boot is too quick to catch, hold Shift while clicking Restart in Windows, then choose Troubleshoot → Advanced options → UEFI Firmware Settings.

Should I always install the newest MSI BIOS version?

No. Versions are cumulative, so the newest file already includes every earlier fix — but if nothing in the changelog affects you, there is no reason to flash. Some AGESA and Intel ME updates also cannot be rolled back, and MSI marks those on the download page.

M-Flash or MSI Center — which is safer?

M-Flash. It runs inside the BIOS environment before Windows loads, so no operating system, driver or background update can interfere mid-flash. MSI Center is more convenient because it needs no USB drive, but it adds failure modes M-Flash simply does not have.
