If my understanding of grub is correct, the execution of
(1) writes the various grub files to the "/boot/grub" directory of
the partition corresponding to the operating system which executes
(2) writes a short instruction phrase to the master boot record
(MBR) of /dev/sda, which phrase terminates in a link to the grub
code in the "/boot/grub" directory of the partition corresponding
to the operating system which last invoked "install-grub".
