BIOS Update
You can run the BIOS update file from Windows using a bootable USB drive or you can also update the BIOS from the F12 One Time
Boot menu on the computer.
Most of the Dell computers built after 2012 have this capability, and you can confirm by booting your computer to the F12 One Time
Boot Menu to see if BIOS FLASH UPDATE is listed as a boot option for your computer. If the option is listed, then the BIOS supports
this BIOS update option.
