I doubt grub 2 will repair a Grub 1 installation.  It is more likely it
will try to replace all the grub files with itself.  In theory, that
should work fine, but I'm not familiar enough with Either Grub 2 or the
Ubuntu GUI install to answer any of your questions.  I only suggested
the easiest way for you to return to familiar footing.
