The order of the entries in the grub menu is based on the order of the file names. File named with a starting numeral are run before those beginning with a letter. The order the files are run determines the menu order in grub.cfg.
Custom entries can be added to the "40_custom" file or in a newly created file.
Any file created must be executable in order to be included in the grub.cfg file during the "update-grub2" command.
o 00_header
o 05_debian_theme: Set background and text colors, themes
o 10_hurd Locates Hurd kernels
o 10_linux Locates Linux kernels based on results of the "lsb_release" command.
o 20_memtest86+: If the file /boot/memtest86+.bin exists, it is included as a menu item.
o 30_os-prober: Searches for Linux and OS's on other partitions and includes them in the menu.
o 40_custom: A template for adding custom menu entries which will be inserted into grub.cfg upon execution of the "update-grub2" command. This and any other custom file must be made executable to allow importation into grub.cfg.
