I was under the impression that mounting the image to an SD card and booting from that would write the image to the SSD. It looks like there a few more steps for me to take before that happens!
The instructions minute gives on this thread seem to be close to what I want to do:
That said, it doesn’t seem to match exactly what I need to do and I don’t have enough experience with a Linux terminal to know which commands apply to my situation.
The handbook mentions the reform-migrate tool on page 50. I opened a terminal and entered “reform-migrate” and tried some of the commands it suggested, but got a “partition not found” message.
This is most assuredly not an idiot-proof device!
