address@hidden:/home/ubuntu# mount /dev/sda1 /mnt
mount: /dev/sda1 already mounted or /mnt busy
mount: according to mtab, /dev/sda1 is already mounted on /mnt
address@hidden:/home/ubuntu# grub-install --rootdirectory=/mnt/ /dev/sda
Unrecognized option `--rootdirectory=/mnt/'
Usage: grub-install [OPTION] install_device
Install GRUB on your drive.

  -h, --help              print this message and exit
  -v, --version           print the version information and exit
  --modules=MODULES       pre-load specified modules MODULES
  --boot-directory=DIR    install GRUB images under the directory DIR/grub
                          instead of the /boot/grub directory
  --grub-setup=FILE       use FILE as grub-setup
  --grub-mkimage=FILE     use FILE as grub-mkimage
  --grub-mkrelpath=FILE   use FILE as grub-mkrelpath
  --grub-mkdevicemap=FILE use FILE as grub-mkdevicemap
  --grub-probe=FILE       use FILE as grub-probe
  --no-floppy             do not probe any floppy drive
  --allow-floppy          Make the drive also bootable as floppy
                          (default for fdX devices). May break on some BIOSes.
  --recheck               probe a device map even if it already exists
  --force                 install even if problems are detected
  --disk-module=MODULE    disk module to use

INSTALL_DEVICE can be a GRUB device name or a system device filename.

grub-install copies GRUB images into /boot/grub, and uses grub-setup
to install grub into the boot sector.
