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 speci-
fying 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.
