This could be due to how you fiddled manually with /gnu/store and
/var/guix.  In general, one should never manually touch these
directories; instead, one should use ‘guix gc’ and similar commands.

To be safe, could you start anew again, and report back?

  sudo rm -rf /gnu /var/guix
  # reinstall from binary tarball

>   (bootloader (grub-configuration (device "/dev/sda9")))

There’s a mistake here: it should be “/dev/sda” (say), not “/dev/sda9”
(the latter designates a partition, whereas the former designates a
disk.)  It doesn’t matter here since you passed --no-grub, but it would
otherwise lead to a ‘grub-install’ failure.

HTH,
Ludo’.
