Did the fix for bug #32122 make it into the Seawolf distro? I downloaded the boot.img file and I see get an fdisk warning message "Partition 1 does not end on cylinder boundary:" treated as a fatal error and the disk is not available to install on. Can you post some updated image files so I can install? Thanks.
Try doing the installation with 'expert' on the boot comand line. In expert mode we ignore this error (note that if you try to delete or create new partitions with a partition table in this state you may have undesirable affects, which is why the warning is there to begin with).
