Comment 8 for bug 109064

While "Start the Ubuntu LiveCD" and "Start in Live mode, without affecting your Hard Disk" both would probably scare a user less, now neither of those options say anything about installing. If I boot from an OS CD and none of the options are "Install", I think I am going to be a little confused.

I like the idea of having a little description appear below whichever option is selected, which would just very briefly explain the details of that option, including (for the first option) that it won't change anything on your computer and will give you the option to install from the desktop.
