Flashing the BIOS from the F12 One-Time boot menu

Updating your system BIOS using a BIOS update .exe file that is 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 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.

• AC power adapter that is connected to the system.
• Functional system battery to flash the BIOS.

CAUTION: Do not power off the system during the BIOS update process. Powering off the system could make the
system fail to boot.
