Code:

sudo mount /dev/sdXY /mnt sudo mount --bind /dev /mnt/dev sudo mount --bind /dev/pts /mnt/dev/pts sudo mount --bind /proc /mnt/proc sudo mount --bind /sys /mnt/sys sudo chroot /mnt grub-install /dev/sdX grub-install --recheck /dev/sdX update-grub

Replace X and Y with disk and partition number e.g. sda1

Code:

exit sudo umount /mnt/sys sudo umount /mnt/proc sudo umount /mnt/dev/pts sudo umount /mnt/dev sudo umount /mnt

Then reboot

Ran a live cd and the /dev/sda1 is not seen, it is mounted at /mnt and won't let me unmount it because it is busy. lol. I have attached screenshots (hopefully).
