Yes, this is what I did.  Thanks for clarifying.

I should've included those details.  The mother board and CPU are just
out of the box.  The company who built the box said to bring it in, I
probably won't be able to get it back until monday.  It's still within
the 30 day warranty period.

If they fix it for free, all's good.  I'm concerned that I did
something to cause this, with regards to GRUB, but don't even know if
that's possible, so am concerned about re-purchasing the same
computer, essentially.
