Solution to not being able to boot off of USB

I have noticed that after the most recent firmware update, that if you have a SD card in your SP3, and attempt to boot off of a USB stick using Poweroff-> Hold Volume Down-> Poweron, that I would get an error about the BCD "\EFI\MICROSOFT\BOOT\BCD" being invalid.

I found if you remove the SD card, I can once again boot up with the restore media, Recovery USB Key image and even the Windows 10 image.

Definitely was pulling my hair out on this one, and even did a HW exchange at MS over this.
