Use the install media to run, as root: grub-install /dev/sda
that is if you want to install to the mbr of the first drive (sda). Did you mount the partition to check to see if any grub files, particularly grub.cfg still exist? You might have to chroot to the partition and run: update-grub, or grub-mkconfig to create a new grub.cfg file if it doesn't exist.
