os-prober isn't installed by default and it's the grub2-related app
that probes other disks and partitions for other OSs.

Once you install it, before over-writing "/boot/grub2/grub.cfg",
either run "grub-mkconfig" and check the stdout output or (for
example) "grub2-mkconfig -o /root/grubtest.cfg". If you're happy with
the result, run "grub2-mkconfig -o /boot/grub2/grub.cfg" to update
your grub boot menu.
