Flashing the BIOS from the F12 One-Time boot menu

Updating your system BIOS using a BIOS update.exe file copied to a FAT32 USB key and booting from the F12 one time boot
menu.

About this task

BIOS Update

You can run the BIOS update file from Windows using a bootable USB key or you can also update the BIOS from the F12
One-Time boot menu on the system.

Most Dell systems built after 2012 have this capability and you can confirm by booting your system to the F12 One-Time Boot
Menu to see if BIOS FLASH UPDATE is listed as a boot option for your system. If the option is listed, then the BIOS supports
this BIOS update option.

NOTE:

Only systems with BIOS Flash Update option in the F12 One-Time Boot Menu can use this function.

Updating from the One-Time Boot Menu

To update your BIOS from the F12 One-Time boot menu, you will need:

●

USB key formatted to the FAT32 file system (key does not have to be bootable)
