If you want to update the system BIOS in a Linux environment such as Ubuntu, see

Flashing the BIOS from the F12 One-Time boot menu

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)
•
BIOS executable file that you downloaded from the Dell Support website and copied to the root of the USB key
•
AC power adapter connected to the system
•
Functional system battery to flash the BIOS
Perform the following steps to execute the BIOS update flash process from the F12 menu:
CAUTION:
Do not power off the system during the BIOS update process. Powering off the system could make the system fail to
boot.
1
From a power off state, insert the USB key where you copied the flash into a USB port of the system .
