I would expect to be able to see the LVM partition, but not be able
to access the LVM file systems unless you are using a LVM-aware OS.
(You may run into problems there is the LVM labels are the same.)

As for the Grub error, I am going to have to go over my notes.
(Where did I put them...) I suspect that for some reason Grub is
trying to access the wrong drive, ether for loading stage 1.5, or
when trying to access the /boot partition's file system.

After the grub error, do you get the grub> prompt? I suspect not,
because it probably can not load stage 2.
