Let me try to clarify. I did indeed have two roots on the same
volume, abeit not simultaneously. The GRUB menu had entries for both

was just multibooting two alternative Linux setups. This was
accomplished by the Xubuntu 12.04 GRUB, which I can no longer access.

I'll try the supergrub. I don't want to get too far from what was working.
