Comment 2 for bug 556373

OK I completed a successful install with only the 80GB drive connected, choosing "entire disc". But I followed it with another install choosing to "resize and choose between OS's" and that install failed with the same error message. I reported that as a separate bug #556458 to hopefully collect all pertinent debugging info.

Just to be perfectly clear, I did not go to the live desktop prior to installing. When presented with the options of running or installing I chose to install. When presented with partitioning options I chose "resize and choose between OS's". From looking at Gparted I can see that the partitioning did complete, but I was still presented with that error message. I then Quit the process to let apport collect info.

So we know it's not limited to multiple drive systems. Also the first time I was presented with that error I had been running a Live session for a bit prior to trying to install, this was not the case in either the subsequent successful "entire disc" install or the failed "auto-resize" install.
