Hi, I am trying to customize an Ubuntu Live CD, with some problem. I need no menu option is available, and that the CD immediately starts booting with the usplash image... I see there is a MENU HIDDEN option, but I don't know how to use it. Here is the original isolinux.cfg: ***************************+ include menu.cfg default vesamenu.c32 prompt 0 timeout 300 gfxboot bootlogo ************************* and here is the menu.cfg file: ***************************** menu hshift 13 menu width 49 menu margin 8 menu title Installer boot menu include stdmenu.cfg include text.cfg include amd.cfg include gtk.cfg include amdgtk.cfg menu begin advanced menu title Advanced options label mainmenu menu label ^Back.. menu exit include stdmenu.cfg include adtext.cfg include adamd.cfg include adgtk.cfg include adamdgtk.cfg menu end label help menu label ^Help config prompt.cfg ********************************* Thank you for assistance.
