I have a similar issue, but the final few lines say that embedding is
required when the root parition is an LVM device (as mine is).

I've got a workstation that works, and the first partition starts at
block 2048. The laptop where I get the error starts at 63. So I suspect
that I am screwed and will not be able to modify my grub2 configuration
until I repartition the disk and leave more room at the beginning. 

I have tried modifying /etc/default/grub and running grub2-mkconfig
-o /boot/grub2/grub.cfg and this has no effect, so I suspect that I am
not really running grub2 or that there is a fixed embedded configuration
that I can't change. Running grub2-install produces the error about the
small embedding area.

What does your disk partitioning look like?
