Updating BIOS on systems with BitLocker enabled
CAUTION:
If BitLocker is not suspended before updating the BIOS, the next time you reboot the system it
will not recognize the BitLocker key. You will then be prompted to enter the recovery key to progress and the
system will ask for this on each reboot. If the recovery key is not known this can result in data loss or an
unnecessary operating system re-install. For more information on this subject, see Knowledge Article:

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

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
