I see from syslog there may be some issue with grub probe.  Here is
verbose output from both drives:

Title:
  install reports unable to install grub to /dev/sdb

Status in grub2 package in Ubuntu:
  Incomplete

Bug description:
  first, I don't know if this is a new bug, but I don't know what bug it matches.  The latest testing kubuntu installer almost finished, then report grub error could not install grub to /dev/sdb.  However, I then used terminal to sudo grub-install --root-directoyr=/mnt/ /dev/sdb
  which didn't report errors, and I assume will boot, but just reporting because installer did not work correctly out of box.
