It might be the UEFI firmware having a problem discovering/registering the EFI file paths (and StartOS doesn’t create a fallback at **/EFI/BOOT/BOOTX64.EFI** I).

I posted a fix/hack for a different device which had a similar problem [over here](https://community.start9.com/t/how-to-make-startos-run-on-minisforum-un1290/3212). Might be worth a try.
