And the other option is to chroot and update/install grub from there (not mine, just copied from another list) :
mkdir /sysroot mount /dev/your-root-dev /sysroot mount /dev/your-boot-dev /sysroot/boot mount --bind /dev /sysroot/dev mount --bind /sys /sysroot/sys mount --bind /proc /sysroot/proc mount --bind /run /sysroot/run (recommended if you are using systemd) chroot /sysroot grub-install /dev/your-grub-boot-device (may be grub2-install on some distro) This is geared to installing on another disk, but should work just the same with multiple OSs on one disk.
