How to Update Your BIOS on Windows 11

Updating your BIOS (or UEFI firmware) on Windows 11 can improve system stability, fix hardware compatibility issues, and even unlock new features. However, it’s also a sensitive process—doing it incorrectly can cause serious problems—so it’s important to follow the correct steps carefully.

Most modern systems now use UEFI firmware instead of the traditional BIOS, but the update process is still commonly referred to as a BIOS update.

In this guide, we’ll walk you through how to update your BIOS on Windows 11 step by step.

How to Update Your BIOS on Windows 11

Before you begin, make sure your laptop is plugged in or your desktop has a stable power source. A power interruption during a BIOS update can damage your system. Also, only update your BIOS if necessary—such as fixing bugs or supporting new hardware.

1. Check Your Current BIOS Version

Before updating, it’s important to know your current BIOS version so you can determine if an update is needed.

1. Press Windows + R to open the Run dialog.
2. Type msinfo32 and press Enter.
3. In the System Information window, look for BIOS Version/Date.
4. Note down the version number and manufacturer.

2. Identify Your Motherboard or Laptop Model

You need your exact system model to download the correct BIOS update.

1. In the same System Information window, find System Model.
2. Note the model name and manufacturer.
3. Alternatively, check your laptop’s label or manufacturer’s website.

3. Download the Latest BIOS Update

Now download the correct BIOS update file from your manufacturer’s official website.

1. Open your web browser.

3. Enter your model number in the search box.
4. Go to the Drivers & Downloads section.

If your system requires a USB-based update, follow this method.

1. Format a USB drive to FAT32.
2. Copy the BIOS update file to the USB drive.
3. Restart your PC and enter BIOS/UEFI (usually by pressing F2, Delete, or similar key).
4. Look for options like EZ Flash, M-Flash, or Q-Flash.
5. Select the BIOS file from the USB drive.
6. Start the update process and wait for it to complete.

7. Restart and Verify the Update

After the update, confirm that your BIOS has been successfully updated.

1. Let your PC restart automatically.
2. Press Windows + R, type msinfo32, and press Enter.
3. Check the updated BIOS Version/Date.
