Can you create the installation media using dd command and test media before install?

sudo dd if=Qubes-RX-x86_64.iso of=/dev/sdY status=progress bs=1048576 conv=fsync

To make sure that there is no issue with the ISO and that ISO was written to the installation media successfully.

Ok. Just to confirm, installing on an external nvme is supported?

I didn’t try to install on external nvme specifically, but installing on a USB disk should work.
