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.
