    • Type System Manufacturer’s name, model number, and  ‘BIOS’ on Google and click on the search button.

    Open System Configuration, as described above in the 2nd step, and check for the BIOS version. Voilà! BIOS version is updated!.

    Limitation for the above method:

    If you download and use incorrect BIOS update files, then it will kill your motherboard and make your PC completely non-working.

    Use the Windows-based program to update BIOS on Windows:

    This is the simplest way to update BIOS on Windows 10. Many manufacturers provide an in-build interface to update BIOS in just a few minutes. For e.g., the WinFlash utility program runs in the Windows environment to restore, refresh, and back-up BIOS. 

    The following steps are for Updating BIOS on the ASUS model of PC/Laptop using WinFlash.

    Open WinFlash:

    1. Download and install Winflash from here.
    2. Search for “WinFlash” application  from “C:/Program Files x(86)/ASUS/.
    3. Double-click on “WinFlash” to start it.
    WinFlash utility program.

    Choose BIOS update Source:

    Once the WinFlash app starts, it will ask to choose from two options.

    1. Choose BIOS from the web option.

    Choose BIOS version:            

    • The application will automatically search on the web and retrieve the latest version of the BIOS file for your System.

    Note(You should  have a continuous internet connection to update BIOS on Windows correctly.)

    • It will prompt the message displaying the current version and update the version of BIOS.
    • Click on the update option.

    There it is! BIOS update is done. You can cross-check it by checking the BIOS version in System Information.

    Limitation of this method:

    Installed software can interfere in the update process and cause BIOS updates to fail and crash your PC.

    Create Dos USB drive and update BIOS on Windows using it.

    This is the old-fashioned, tedious way to update BIOS on Windows.

    1. You need to create a bootable flash drive using an external tool like Rufus.
    2. Then copy the BIOS update file into that drive.
    3. Execute the batch file with extension.bat provided with the BIOS update file to start the update process.
    4. Sometimes scripts have to be downloaded separately from the web.

    Bottom line: Updating BIOS on Windows is a critical process and you should go for it one only if there is no other workaround to resolve some specific hardware issues. And you have to double-check each step before implementing it to avoid any failure.
