As I wrote before, once you=E2=80=99ve booted into GuixSD, chances are that=
 the
original distro on that partition is in a bad state because GuixSD has
fiddle with /etc and other global directories.

Could you explain the KMS issue in a separate thread?

It=E2=80=99s enough to modify grub.cfg.  GRUB itself is not needed.

But anyway, the take-home message is that if you run =E2=80=98guix system i=
nit=E2=80=99
on your current root, then you can assume the former distro to no longer
be bootable.

Thanks,
