Hello,
> After formatting the drive completely with another live USB the NVME was then > correctly detected by the Guix installer. > > This issue occured both on the 1.1.0 stable installer ISO and the latest > installer ISO as of August 1 2020. Thanks for the report, I'm also able to reproduce this issue in a VM. For some reason a disk containing an LVM partition does not show up in the disk selection menu of the graphical installer. I'll investigate this issue. Mathieu
