Solution: If the BIOS firmware update fails to complete, try restarting your computer and running the update process again. If the issue persists, try using a different USB flash drive or external storage device to save the updated firmware file.

  • Issue 2: Your system fails to boot up after the update.

In rare cases, you may encounter issues when attempting to boot up your system after a BIOS update. This can be caused by a number of factors, including incompatible hardware or incorrect BIOS settings.

If your system fails to boot up after a BIOS update, there are a few steps you can take to resolve the issue:

  1. Clear the CMOS
    Clearing the CMOS can often resolve issues with the BIOS, including boot-up failures. To clear the CMOS, locate the CMOS jumper on your motherboard and move it to the “clear” position. Alternatively, you can remove the CMOS battery for a few minutes to clear the settings. Once you have cleared the CMOS, try to boot up your system again.
  2. Revert to the previous BIOS version
    If the new BIOS version is causing your system to fail to boot up, you may need to revert to the previous BIOS version. To do this, you will need to locate the previous BIOS version and use a flashing tool to revert to it. Be sure to follow the same steps as when flashing the BIOS, but this time select the previous BIOS version instead.
  3. Seek professional help
    If you have tried the above steps and your system is still failing to boot up, it may be time to seek professional help. Contact the manufacturer of your system or a qualified technician who can help you diagnose and resolve the issue.
