NAME
       grub-reboot - set the default boot entry for GRUB, for the next boot only

SYNOPSIS
       grub-reboot [OPTION] MENU_ENTRY

DESCRIPTION
       Set the default boot menu entry for GRUB, for the next boot only.

       -h, --help
	      print this message and exit

       -V, --version
	      print the version information and exit

       --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  sepa‐
       rated  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 de‐
       vice, the chosen boot menu entry will remain the default even after reboot.
