You should have regenerated grub.cfg with update-grub(2) instead.
I went ahead and did a:
# grub2-install --root-directory /boot /dev/sda
It should be --boot-directory (or nothing, as /boot is the default).
--root-directory is an obsolete hidden option which sets the target root
directory. So I guess you installed GRUB in /boot/boot/grub and $prefix
is set to (hd0,msdos7)/boot/grub.
