Too many unknowns...


A troubleshooting suggestion:
If you haven't done so already, repeat your test/experiment with a download of the Raspberry Pi supported Raspbian Operating System.

If that works, as I suspect I will, it will verify the usb medium, the use of Etcher, and your modification to the boot configuration of your RPi board.

In which case the remaining incompatible element is that the third-party OS you are trying to boot may not have been made ready for this method of booting.
