Help - Live Disk Problem

Greetings, Having installed TDE successfully on my desktop, using tde-3.5.13.2-ubuntu-12.04.2-desktop-amd64.iso, I have struck a problem with my laptop. Although I have previously installed many other GNU/Linux distros on it the live disk installs happily but won't install to the hdd. The disk was written on the laptop. When I select either the install icon or the item in the menu the CDROM comes to life then stops. A puzzlement! Is there is a command line I could use? Can anyone help me finally escape KDE4 using the live disk please? David W. Devon
