Hello,
>> I'm installing from a USB thumb drive. I'd like to use the thumb drive >> as the disk for the machine. The installer gave me the option to do >> so, but then it crashed. Christine is right, in that case you might prefer to use "guix system image" to create directly a bootable image that suits you. >> I can imagine that installing on the installation media is not >> supported. Perhaps the installer should have prevented me from doing >> so? Yes indeed. The latest installer available here: https://guix.gnu.org/en/download/latest/ should hide the installation media in the device selection page. It would be great if you could confirm it. Thanks, Mathieu
