Thanks, after what DJ said, I think that hybrid isos will be fine
with 'dd'.  But I'm still not sure why using bs=4M transferred less
than bs=512K in my failed tests.

That is weird, but I suspect there may be some trailing garbage being transferred in some cases.

You may need to go into the firmware to get it to boot via the USB stick.


Yes - UEFI seems to be an order of magnitude worse than BIOSes.

It has been my experience that on most UEFI firmware you can turn off secure boot. Then if the disk does not have an efi partition, it boots just like the old BIOS based firmware.
