Not matter what option chosen, the bios operation fails. Upon closer inspection, you might notice a that the ME updated failed with error 0x000001B9.
Dell has an office KB doc here:

But it is not obvious how to end the loop.
Here is how to get out of the Dell Bios Recovery Menu loop on a Dell Precision (7550/7750):
- -get service tag.
- -go to https://dell.com/support (on another system).
- -get newest bios (it will be an exe file).
- -put the file on USB drive (does not have to be a bootable USB).
- -power off system.
- -unplug power source.
- -hold CTRL+ESC buttons.
- -plug power source in (you will not need to press the power button).
- -BIOS RECOVERY MENU eventually shows with 3 options (as shown in pic above):
- 1-RECOVER BIOS
- 2-SET BIOS SETTINGS TO DEFAULT
- 3-ROLLBACK BIOS
- -press CTRL+ALT+DELETE (sometimes CTRL+ALT+END)
- -system will reboot.
- -press F12 for one-time boot menu.
- -select FLASH BIOS UPDATE.
- -plug in USB DRIVE.
- -select the BIOS exe file.
The BIOS update will start and should go all the way through and reboot on its own.
