Download current BIOS to a FAT32 flash drive from the Dell site. With flash drive connected, turn power, F12 for Boot Menu, boot from flash drive.

Same problem here.
The reason seems to be the "is not signed" status of the BIOS Update. This was the case for many previous Bios Updates of various models.
Unfortunately using a flash drive, or installing by hand is no option in my case.
@Dell: Please sign the *.exe file.
Thanks in advance :)

Another BIOS trick if it's not installing to disconnect all external peripherals except for mouse, keyboard, and monitor.
