windows 10 - The selected boot device failed. Press any key to continue

I am attempting to create a bootable USB drive to install Windows LTSB on my computer. To do so I have taken the following steps.

1) Procured an ISO file containing Windows LTSB

2) Tested that this ISO file worked by a] verifying its checksum and b] opening it with Virtualbox

3) Use Rufus to create a bootable USB drive like so:

4) Launch UEFI and change the following settings (the following is not exact wording):

• Secure boot to off


• "Legacy boot" to on or off (either option didn't work)


• "Allow legacy ROMs to on"

I would then re-launch my computer and press F12 to select a bootable drive. While I could select a bootable drive labeled as "Mass Media Storage Device" - it would not launch and instead would give the error described in the post title.

How can I fix this error, or at the very least, determine if the problem is with my UEFI settings or flashdrive?
