          --boot-directory=,DIR/
               expect GRUB images under the directory DIR/grub instead
               of the ,/boot/grub/ directory

          MENU_ENTRY is a number, a menu item title or a menu item
          identifier. Please note that menu items in submenus or
          sub-submenus require specifying the submenu components and
          then the menu item component. The titles should be separated
          using the greater-than character (>) with no extra spaces.
          Depending on your shell some characters including > may need
          escaping. More information about this is available in the
          GRUB Manual in the section about the 'default' command.

          NOTE: In cases where GRUB cannot write to the environment
          block, such as when it is stored on an MDRAID or LVM device,
          the chosen boot menu entry will remain the default even
          after reboot.
