Comment 36 for bug 1886148

My Lenovo V130 does not boot from a cloned drive, and did not boot from a persistent live drive by mkusb-dus. But with today's iso file, there is progress. It boots into a persistent live system with the boot option 'upefi', usb-pack-efi, (and there is persistence). So another way to see what works is to look at

- a persistent live drive, and particularly the boot partition,

- the tool that creates it, the bash shellscript 'dus-persistent'

There are details at

When things have improved further and also the problematic computers boot from cloned iso files, they will probably also boot when mkusb used the default settings, where the system is created instead of extracted from the usb-pack-efi file.
