Further to comment #9 (with the idea of work-around) I initial-booted the thumb-drive (installation media) but by editing the grub entry (so instead of booting it normally; it booted the installed (sda1) system instead using `chainloader (hd1)+1`)
and my installed version booted.
I ejected the thumb-drive and tried to grub-install but get
guiverc@dc7700:~$ sudo grub-install /dev/sda
[sudo] password for guiverc:
Installing for i386-pc platform.
grub-install: warning: this GPT partition label contains no BIOS Boot Partition; embedding won't be possible.
grub-install: warning: Embedding is not possible. GRUB can only be installed in this setup by using blocklists. However, blocklists are UNRELIABLE and their use is discouraged..
grub-install: error: will not proceed with blocklists.

I'm fearful this won't boot... so no workaround..
