Written By Steven Arends

Do you get the error message of “No Image File  Detected” when you try to update the BIOS 

Of your Asrock motherboard.

It’s a common error when updating your BIOS in an Asrock motherboard.

Don’t be frustrated about this. It’s pretty easy to fix this error and just follow simple steps to resolve the issue.


In this post, I will show you how to fix the error of BIOS not detecting the Image file.

But first, you have to learn about BIOS Update, UEFI settings, and some other essential things related to this topic.

So, Let’s start.

What is a BIOS Update?

BIOS update is a process that solves the problems occurring with your computer hardware. Generally, BIOS updates correct the hardware incompatibility issue of the PC. Sometimes it also updates the capacity, capabilities of hardware.BIOS update needs when drivers or OS do not fix a hardware problem.

If you face any hardware problem, then you should only update your BIOS. If your computer is working fine, you don’t need to update your system BIOS. You are recommended to update your BIOS to fix a problem when your motherboard’s manufacturer suggests a BIOS update.

Because Updating your BIOS is not as easy as updating your software. If you do an improper BIOS update, your hardware can be damaged.

As updating the BIOS is complex, you will face some errors. Not detecting the image is one of them.

It has most commonly happened when you update your Asrock BIOS.

I will write about the reason behind this error and how to fix this issue.

Why is Asrock BIOS not Detecting Image Files During Updates?

There are various reasons why your Asrock motherboard’s BIOS does not detect the image file while updating the BIOS.

Here I write the most common reason for this issue:

1. Wrong format of your USB

This is the most common reason for this issue. Your BIOS will not detect any Image file if you select any wrong version to format your USB flash drive.

Suppose you format your USB in NTFS. Your BIOS will not support this format.

2. Selecting Wrong BIOS update

Selecting the wrong BIOS update file is another reason for this issue. If you do not select the specific updates for your BIOS, it cannot select the image files while updating the BIOS. In this case, your image file will not be compatible with your BIOS updates.

Suppose you download the AB350 Pro motherboard’s BIOS update file, but your motherboard model is Asrock AB350M pro. So your motherboard doesn’t detect the image files for the wrong version of updated files.

3. Not unzipping the update files

If you are not Unzipping the update files, this issue will happen because BIOS can’t read the default zipped file.

4. Wrong UEFI settings

If your  Unified Extensible Firmware Interface (UEFI) setting is wrong, your BIOS update can’t select the image files.

This is the reason for BIOS not detecting the image files.

Now I jump into the solution of fixing this issue.

When your Asrock BIOS update does not detect image files?

To solve this issue, you have to follow some simple methods. Complete the steps to success.

Here I describe the methods to solve this issue:

1. Format your USB with FAT32

To update an Asrock BIOS, your flash drive should be formatted with FAT32, not NTFS. Otherwise, BIOS can’t open the updates.

But most of the flash drives are default formatted with NTFS. 

So you have to format your USB flash drive to FAT32 for updating your BIOS.

Here are the steps to format your USB with FAT32:

By Disk Management

  • Go to the start button of your PC and right-click on it.
  • Now search for the Disk Management option.
  • You will find a USB menu on the pop-up screen. 
  • Now right-click on the USB.
  • Select the format option.
  • Now find the FAT32 option at the dropdown list.
  • Then click on it.
  • Now hit the OK button to save the changes.

Directly Format to FAT 32

  • Press win+E key for going to File Explorer.
  • Find your USB flash drive and right-click on it.
  • Choose the Format option.
  • Now select FAT32 from the dropdown list.
  • Now press Start.
  • Your USB will be formatted to FAT32.

These are the steps to format your USB with FAT32.

Now download the proper updates for your BIOS.

2. Download proper BIOS update

Download the correct version of your update file for your BIOS. This is very important for updating your BIOS because if you choose the wrong version of BIOS, it can harm your hardware.

You have to be very careful when you choose the updates for BIOS. You should download 

The exact version of the update for your BIOS.


Here are the steps for downloading the updates:

  • First, go to the website of Asrock.
  • Then go to the product section, and select Motherboard from there.
  • Now select the exact motherboard you have.
  • Select your motherboard from the left navigation list.
  • After the selection, you have to go to the BIOS option.
  • A long list of versions will appear on your screen.
  • Now select the exact version of your motherboard.
  • Now download the zip file.

Most people make mistakes when they download the BIOS updates. Because model numbers of the motherboards are pretty similar. Such as AB340 and AB340M are pretty similar named motherboards but their update versions are completely different.

So select your BIOS update pretty carefully.

3. Unzip the update file

It’s a silly mistake, but your BIOS will not update appropriately for this mistake. When you download the file, it is zipped.

You should unzip the file before you add it to the flash drive for BIOS.


Here are the steps for unzipping the file:

  • Select the file and right-click on it.
  • Now select the extract option from the list.
  • Select a location for extract.
  • Now press start.
  • Your Downloaded file will be unzipped.

These are the BIOS and Image detection issues for the Asrock motherboard.

But you should update your BIOS properly to get the BIOS Image. 

In the following passage, I will write down the proper way to update your Asrock BIOS.

How do you update Asrock BIOS?

For updating your Asrock motherboard’s BIOS, you have to follow some steps.

I will describe the steps here:

  • First, you must save the unzipped BIOS file to the FAT32 Formatted USB drive. You can drag the file to your USB.
  • Now turn off your computer and connect the USB to the dedicated USB port. If you have USB 2.0, then connect it to the 2.0 port.
  • Now press the start button and continuously click the specific button to enter your PC’s BIOS.
  • If your BIOS screen appears, then go to the tool section, and it can help you to flash your BIOS.
  • Once you enter into the tool menu, you can navigate the cursor to the instant flash option and select the option.
  • Now select the option, and a popup tab will appear, where you can see the downloaded BIOS version on your USB flash drive.
  • Now press the update button.
  • You will see a confirmation message “Do you want to update your UEFI to (Downloaded version).”
