According to this link, GRUB 2.00 has just been released. How can one upgrade to this?

Danger!
GRUB is your bootloader -- the first piece of software to start after you switch on your computer, and responsible for loading the operating system. Grub 2.00 has not been tested by Ubuntu and any problems may render your system unbootable--including Windows if dual-boot--and will require a LiveCD/LiveUSB and time to fix.
Unless you simply want to experiment, it is highly recommended to wait for Grub 2.00 to officially make its way into Ubuntu (or at least until 2.00 shows up in Debian Sid or the Quantal alphas!)
That said, Linux/FOSS is about freedom, and if you get the gun, I'll teach you how to shoot! :)
If you still want to install Grub 2.00 after the warnings above:
You'll have to build it from source. Open the terminal and type/paste:
sudo apt-get build-dep grub2 wget -O- ftp://ftp.gnu.org/gnu/grub/grub-2.00.tar.xz | tar -xJ cd grub-2.00 ./configure --prefix=/usr make sudo make install
Now, you need to install the new Grub to where your existing Grub is. If you don't know where or how to find out, quit now!
- If you have a dual-boot system, be especially careful about whether you should install to the disk or to the partition!
- Replace sdq as appropriate:
sudo grub-install /dev/sdq
- Run
sudo update-grub
Reboot, and...it's slightly different...
Advanced Options gives us the reassuring....
But "GNU/Linux" seems to work anyway...
Uninstall?
No guarantees, but sudo apt-get --reinstall install grub2
should overwrite Grub 2.00 with the official 1.99x version.

Read your warnings, and got that overwhelming feeling that I should not try this. ;) Well, I will wait as you mentioned. I'll accept the answer and upvote since this answers the question for those daring souls who want to try this. :) Jun 30, 2012 at 3:16
