[lubuntu] Removing the installation menu on custom LiveCD

view story

http://ubuntuforums.org – I'm currently building a custom lubuntu-based LiveCD using Ubuntu Customization Kit, and it's been so far so good, but I need to somehow remove the installation menu that shows up when you boot into lubuntu (the one that has the "Try Lubuntu without Installing" option), I just need it to jump straight into the desktop environment without prompting the user to install lubuntu, as it's always going to be run under a LiveCD environment, but I just don't know how to do it, and haven't found much info about this, any help? Thanks in advance (Hardware)
