RE: Dell Inspiron 3421 Corrupted Bios - How to boot from USB?

Hi WilliamSYWong,

Thanks for posting.

It is possible that the motherboard may need to be replaced.  If you are under warranty, you may wish to consult with Tech Support for a possible resolution or repair.  If you are out of warranty you could choose to replace the MB yourself or have a local computer shop repair it for you.
