I had already run into that, thanks.

and ignored I assume.  But what then causes the grub2 stuff to be loaded 
from /dev/sdX's MBR and a restart then done using grub2's menu's?  The 
"chainloader + 1" I have previously tried and wasn't able to make it work, 
with or without spaces surrounding the '+'. Probably a typu on my part, but 
the docs, what there is, are exceedingly sparse on the rules and syntax to 
make grub actually do its dance.
