Im giving a go fedora silverblue on a new laptop but Im unable to boot (and since im a linux noob the first thing i tried was installing it fresh again but that didnt resolve it).
its a single drive partitioned to ext4 and encrypted with luks (its basically the default config from the fedora installation)
any ideas for things to try?
You should let the installer do the partitioning. Silverblue and immutable systems are nitpicky about it. Specially if luks is involved. The whole point is that you shouldn’t meddle with the system at a low level at all.
