In default Ubuntu ISO, the menu labeled "Install Ubuntu" includes only-ubiquity in its boot command. In default Kubuntu the menu labeled "Start Kubuntu" includes maybe-ubiquity, which will show user whether to Try Kubuntu or Install Kubuntu in a single window without desktop environment.
The problem is, only-ubiquity and maybe-ubiquity commands never worked on my remix [which is built on top of Ubuntu Mini Remix 10.04], while the default Ubuntu 10.04 ISO works fine. Moreover, I don't know how ubiquity installer is activated at boot.
Can anyone tell how to fix this problem (or at least explain how to use ubiquity installer at boot)?
