I understand that the "start" file is the main menu and the other is the sub menu... but I cannot see how one is linked to the other?

The two directories in bootloaders: grub-pc and syslinux-common are for configuring the EFI and syslinux menus respectively.

In grub-pc/, install_gui.cfg and install_start_gui.cfg are both called from grub.cfg
You can arrange the submenus how you want.

The syntax for the syslinux menu is slightly different but the files shipped with live-build should illustrate it.
