Comment 13 for bug 609815

@xiss burg, @bcbc, okay xissburg clarified something i'd not known: that on xiss burg's system Wubi was installed not on the Windows 7 partition, but on another partition that didn't have a windows system on it. So this seems to reinforce bcbc's theory that the key is installing Wubi on a non windows system partition and subtract from my alternative theory that it is related to just installing on a later partition (2nd or later) than the first created partition.
