Comment 12 for bug 1254374

According to the logs it was using /dev/mapper/isw_bfajajcabd_Volume0p1, which is correct. The only thing out of the ordinary I see is an exception trying to write the new partition table, but the nature of the exception is not logged. Could you try manually running sudo parted /dev/mapper/isw_bfajajcabd_Volume0p1, and deleting the existing partitions?
