How to Easily Upgrade Grub Legacy to Grub 2

How to easily upgrade Grub from Grub Legacy (0.97) to Grub 2 (1.96) in Ubuntu 9.04:

First start the Terminal: Applications => Accessories => Terminal
Update the Ubuntu update list by typing this command:
```
sudo aptitude update
```
Now install grub:
```
sudo aptitude install grub-pc
```
a. When it asks for Y/n to continue, type Y and hit Enter.
b. When the Configuring grub-pc screen pops up, click Enter; this would choose Yes by default.
c. Next screen “Linux command line:“, click Enter again.
Once the installation is complete, restart your computer by typing:
```
sudo reboot
```
On some computers, you may see this error:
Error 11: Unrecognized device string => just hit any key to continue
At the “Chainload into GRUB 2” screen, select Chainload into GRUB 2 and press “e”
Select the entry which begins with “root” and press “e”
Use the arrow keys on your keyboard to move your cursor to “root” and remove the word “root“ => now type in the word “uuid“. The line should then look like:
After you finish typing the word “uuid” and your entry looks like the screenshot above, hit Enter. You will then see something like this:

=> Now with the uuid line still highlighted, press “b” to boot your computer.

You should then see something like this (with possibly different kernel versions) then your computer boots up
Once your computer finished booting, start the Terminal again and type this code to finish the GRUB 2 Upgrade:
```
sudo upgrade-from-grub-legacy
```
