Grub2 Tutorial, Part 3 (Shallow Thoughts)

Grub2 Tutorial, Part 3

Part 3 and final of my series on configuring Ubuntu's new grub2 boot menu. I translate a couple of commonly-seen error messages, but most of the article is devoted to multi-boot machines. If you have several different operating systems or Linux distros installed on separate disk partitions, grub2 has some unpleasant surprises, so see my article for some (unfortunately very hacky) workarounds for its limitations.

Why use Grub2? Good question!
(Let me note that I didn't write the title, though I don't disagree with it.)
