It says it can't find the filesystem labelled 'my-root'.

These labels can be set and queried while creating filesystems, or
afterwards with `fdisk`, `e2label` (from e2fsprogs) or `btrfs filesystem label`
(from btrfs-progs).

So, can you share the file-systems section of your system configuration?
And, how is your storage partitioned and the filesystems laid out?
