Good advice! I wasn't sure what you meant by "erase from the hardware", but I used Disk Utility to remove the volume (it automatically removed both parts of the linked OS backup volume, the main one and the "Data" one); I added back a new (single-part) volume in Disk Utility; used SD! to erase then backup (it created the second part, of course); and now option-restart shows only a single disk to boot from and it boots just fine.
