How to Update ASUS BIOS

A Comprehensive Guide on How to Update ASUS BIOS

The Basic Input Output System(BIOS) is the first software that starts on your computer when you turn it on. It is responsible for controlling crucial hardware components, such as the keyboard, mouse, hard drive, and more. Keeping your BIOS up to date is vital as it can enhance system performance, fix any bugs, and improve security. ASUS offers an easy-to-use BIOS updater tool that will help you update your BIOS. In this guide, we will take a comprehensive look at how to update ASUS BIOS.

How to Update ASUS BIOS

Step 1: Preparing for the Update

The first essential step is to check your current BIOS version, which can be done by accessing the BIOS screen during boot-up. Note down your current BIOS version, model number, and motherboard model. You can download the latest BIOS version from the ASUS support page, where you will need to select the product category, standard series, and model name to access the latest BIOS updates.

Step 2: Creating a Bootable USB Drive

The next step is to create a bootable USB drive where you will load the new BIOS version. You can use third-party software such as Rufus to create a bootable USB drive easily. After downloading the latest BIOS version from the ASUS support page, store it on your new USB drive.

Step 3: Updating the BIOS

Once you have created a bootable USB drive, restart the computer, and press the relevant key to enter the BIOS. The key will vary depending on your ASUS motherboard model. Use your arrow keys to navigate to the “Tools” section and select the “ASUS EZ Flash” utility. You will be given the option to browse the USB drive to locate the new BIOS update. Once you have found it, click on “Start Flash” and wait for the update to complete. Do not interrupt the process or turn off your machine as it could result in permanent damage to your hardware.

Step 4: Restarting and Verifying the Update

After the update is complete, restart your computer, and enter the BIOS screen again. Locate the BIOS version to confirm the installation of the new update. ASUS usually provides release notes for each update, which you can use to verify that the new BIOS version has been installed correctly.

Step 5: Troubleshooting

Sometimes, updating the BIOS can result in unforeseen problems. If that happens, attempt to clear the CMOS, which will reset the BIOS to default values. You can also remove the motherboard battery for about five minutes and then reinstall it to reset the BIOS. If none of these methods work, contact ASUS customer support for further assistance.


Updating your ASUS BIOS is a crucial step in keeping your system running smoothly. With this guide, the process becomes more straightforward as you can see the step-by-step instructions provided. Always ensure that you download the correct BIOS update for your motherboard model and follow the instructions carefully to avoid any issues. If you have any issues or concerns, do not hesitate to reach out to ASUS customer support. The procedure may seem daunting at first, but with the right tools and steps, you can keep your BIOS up to date and avoid any unforeseen problems
