OK, found my problems.
The boot toogle flag from fdisk had not been set.
I had a feeling there was something overlooked, but
my head was in OS level stuff and all of the newness
I was dabbling in (ext4, metadata level, grub2).
I was't seeing a Grub screen from the intended disk,
as the BIOS was sending me off to the old disk
where I must have done something to affect its grub
I should have tried detaching the original disk way before now.
It was partly compounded by odd behaviours in the Debian
rescue CD for reinstalling the grub. I was able to launch
the system from SuperGrub 2 and then I found things like
dpkg-reconfigure grub-pc worked fully (not so in rescue
CD chrooted shell to root, even with /var and /usr mounted).
Anyway it's up and running.
