             I went to this location and they had this:


    Commands list

This is a list of the commands executed in order,

   1.

      *sudo fdisk -l*

   2.

      *sudo mount /dev/sda1 /mnt*

   3.

      *sudo mount --bind /dev /mnt/dev*

   4.

      *sudo mount --bind /proc /mnt/proc*

   5.

      *sudo mount --bind /sys /mnt/sys*

   6.

      *sudo chroot /mnt*

   7.

      *(optional, only if you're on Ubuntu/Debian) apt-get install grub-pc*

   8.

      *grub-mkconfig -o /boot/grub/grub.cfg*

   9.

      *grub-install /dev/sda* (try *grub-install --recheck /dev/sda* if
      it fails)

  10.

      *Ctrl+D* (to exit out of chroot)

  11.

      *sudo umount /mnt/dev*

  12.

      *sudo umount /mnt*


     I believe 2. should be "sudo mount -t ext4 /dev/sda /mnt"
Steps 3. 4. 5. are not needed. At 8. you can use "update-grub" which is 
the same as he shows see "man update-grub". 9. is bad if grub-install 
/dev/sda fails. The man page shows nothing like this.
The rest are fine.

     All definitive web pages are not accurate.
