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 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.
