You did not explain what you want to obtain.

My guess is, that you need to do this:

sudo mount /dev/sd* /mnt/point_root_directory_of_linux_install
                  ^ replace * with device of the root directory

sudo systemd-nspawn -bqD /mnt/point_root_directory_of_linux_install

or alternatively

sudo chroot /mnt/point_root_directory_of_linux_install

chroot might requires to mount more, then just the root directory
partition, as far as I know systemd-nspawn does it automagically.


sudo grub-install /dev/sda
