The instructions you followed were okay, but they were probably wrtten for all Linux distros. Ubuntu is different from other Linux distros. We have special security in place which requires us to use the word 'sudo' before any command that will make system-wide or important changes.

1. I insert the Ubuntu cd into the cd rom and select run Ubuntu without any thing to your computer (i mean first option).
2. I open the Terminal and type the following commands

sudo fdisk -l
sudo grub
root (hd0,2)
setup (hd0)If you open your GRUB shell with 'sudo', you will be asked for your passwoprd, (unless you just typed it in the last few miutes), and you'll be given a shell with 'root' priveleges. (administrator power).
If you forget or don't know you need to use 'sudo', you'll still have a GRUB shell, but it won't be very useful.

EDIT: Also, make sure you type '(hd0)' - as in H D zero, the number zero, - don't type '(HDO) - H D O as in 'O' for orange.

Always keep a SuperGrub disk handy, its got me out of similar problems more than once, ( I like to try out different distros, but always come back to Ubuntu ).
