Why does the WININSTALL USB that Boot Camp Assistant created give me the No Bootable Device error?

I have an official MSFT Windows 7 Ultimate x64 install image. I used Boot Camp Assistant to make a "bootable" USB installer with the microsoft image. And when I go to install Win 7, I get "No Bootable Device found -- insert disc and press any key"

I'm using a mid-2012 MBP, not Retina, running El Capitan, though I'm thinking about wiping it and going back to Yosemite. All latest patches & such have been applied. Also, if I boot and press option, I see the WININSTALL USB stick. I select it, and "No Bootable Device found..."

Help!

MacBook Pro, Mac OS X (10.7.5)

Can you verify that your USB is a USB2 flash drive?

Do you have access to another USB 2 flash drive of a different brand/model which 8+ GB? If yes, can you use it to test.

Used a 128gb flash drive. Same result. I think it's just not going to work. Time to wipe and reinstall again.

Too large a USB drive is also problematic, because there is an invalid assumption that you want to install on an external device large enough to host an OS. I have seen past failures with 64GB flash drives.
