Comment 3 for bug 374202

just tried mounting the two existing partitions and THEN running the install from the desktop icon of the live-cd; the installer gets to Keyboard layout and then "Prepare Disk Space" where it says "This computer has no operating systems on it" and offers to use the entire disk, or to alteratively select to specify partitions manually where the diagram shows only one partition.

the previously shown partition icons vanish from the desktop although the /media/disk and /media/ubuntu paths are still mounted and still readable.
