Comment 5 for bug 738366

Can someone that is able to reproduce this with multiple operating systems installed please run the installer in debug mode (press "Try Ubuntu" on the first screen, then open a terminal window and type `ubiquity -d`). Run through the installer until you get to the first partitioning page, then quit and run `apport-collect 738366`. Please also attach the output of `sudo os-prober`.

Thanks
