This could be an instance of the problem that bit me last night.  The
version of Guix that gets installed (0.6, as you mentioned in your
notes), uses an initrd that cannot see SATA hard disks.  So, as a
work-around, you must explicitly add the relevant kernel modules in your
operating-system definition like so:

  (use-modules (gnu) (srfi srfi-26))
  
  (define my-os
    (operating-system
      ...
      (initrd (cut base-initrd <> #:extra-modules '("libahci.ko" "ahci.ko")))
      ...))

Additionally, as Ludovic has already mentioned, I find that using device
labels is much better than hoping that the /dev nodes on the
installation image are the same as the /dev nodes on the installed
system.
