How do I edit the GRUB menu in Grub2?

[Scott Beamer]

Apparently menu.lst isn't a part of Grub2.

I'm running lucid right now and the Grub menu is a mess.

I want to

	A) Remove reference to a hidden Windows (recovery) partition

	B) Switch the default OS to Windows instead of Ubuntu.

Also, after a recent update, I've now got a GRUB splash background 
(Debian artwork) and I can't figure out where it came from. I've done a 
search on "splash" in Synaptic and came up empty.

I want to go back to no graphic image on the GRUB menu.

Thanks.
