In most cases, you can update BIOS by the Windows update Tool. You just need to go to ASUS website to download a proper BIOS update installer for Windows. Then unzip the file and execute the BIOS update installer file. After that, you just need to follow the on-screen instructions to complete the preparation work and then restart the PC to begin updating BIOS.

However, sometimes BIOS update may fail, because the operating system is poisoned, or there are a large number of resident programs and other unstable factors. In this case, you can use ASUS EZ Flash to update the BIOS version without entering the Windows operating system.

To update BIOS with ASUS EZ Flash, please follow steps below:

Step 1: Please back up your personal file before upgrading BIOS to prevent any unexpected issue.

Step 2: Keep the power supply / AC adapter connected during the BIOS update process.

Step 3: Prepare a USB drive. You should make sure this drive has only one partition on it and the partition should be FAT16/32. If necessary, you need to delete all partitions on the drive and then create a FAT32 partition, or you need to format the drive to FAT32 file system.

Note: If you fail to format the USB drive to FAT32 because it is larger than 32GB, you can use MiniTool Partition Wizard, which can help you solve the problem as long as the USB drive is no more than 2TB.

Step 4: Download the latest BIOS file corresponding to your motherboard model from ASUS Download Center. If you don’t what your motherboard model is, you can check that in BIOS, System Information, or DirectX Diagnostics Tool.

Step 5: Unzip the BIOS file. After unzip, a .CAP file will appear. This is the BIOS update file. Save it in the USB flash drive. Please make sure the .CAP file is in the root directory of the USB flash drive.

Step 6: Connect the USB flash drive to PC. Restart PC and then press the keyboard DEL key when ASUS LOGO appears, so that you can enter ASUS BIOS interface.

Step 7: In the BIOS screen, press F7 or click Advance Mode with the mouse to enter the advanced mode. Skip to Tools page and you can see ASUS EZ Flash Utility. Click this tool and then choose the USB drive > the .cap file. Then, after confirming some information, the BIOS update will start.
