Hi Antony,
The iso file came from the Berkely mirror. The files you list are
actually on there. The confusion was caused by my mistake in looking at
the usb stick. On this computer usb automounts when plugged in. An ls
/media/usb0 shows two files under /efi/boot/. I dd'ed the .iso to
/dev/sdb which maybe is not correct?
/sbin/fdisk -l shows the stick now has sdb1 and sdb2. The automount
picks sdb2. If sdb1 is mounted instead the files you show are there.

So we are back to square 1. The usb stick should be a valid boot device
and the mini-pc doesn't like what it sees there. It does see the stick
because the led comes on and at times it blinks rapidly.

I don't know what else to do.
Best regards,
Fred
