    Yes thank you. Was trying to boot an encrypted OS from a USB flash drive and this was the culprit. I wonder if leaving this off will cause any errors so I can continue doing what I'm doing. This is on a Surface Pro 3 that has been replaced by a Surface Pro 4 so the 3 is my play around device.

    Alright I tried following your steps here but it will not let me turn secure boot off it won't even give me an option to turn it off but the "Secure Boot Violation" says "The system found unauthorized changes on the firmware, operating system or UEFI drivers. Press [OK] to run the next boot device, or enter directly to BIOS Setup if there are no other devices installed. Go to BIOS Setup > Advanced > Boot and change the current boot device into other secured boot devices." The thing is there's only one installed device to use plz help if you can...
