Edit PXE menu to create sub menus

This article helps you modify "/tftpboot/pxelinux.cfg/default" file to easily create sub menus and going back to main menu. Notice that you can change sub-menu title and background (and others) by including those parameters inside it. Of course, you can create sub-sub menus.
