What do you mean with "ubuntu refuse to start"? Can you clarify where the 
boot process stops?

I think you should at least get this GRUB boot screen:

| GRUB Loading stage1.5.
|
| GRUB loading, please wait...
| Press 'ESC' to enter the menu...

If you see this message, press ESC and you get the GRUB menu with the 
default OS version highlighted. Now press the "e" key and you get a new 
screen where you can edit the boot options. The first (highlighted) line 
should be something like

root (hd 0,5)

where the "0" marks the drive and "5" marks the partition on the drive 
from where GRUB should read the kernel. Your numbers are probably 
different. You should modify this line by entering the "e" key. Increase 
the number designating the disk, ie.e change the line that it looks like

root (hd 1,5)

where you must not change the number designating the partition ("5" in the 
example above). Now hit the "Enter" key and the "b" key. Then the system 
should boot.

If that all worked you should make the changes permanent. After your login 
enter this command in a terminal:

gksu gedit /boot/grub/menu.lst

locate the line which reads

# groot=(hd0,5)

and change it like this:

# groot=(hd1,5)

Again, only change the drive number. Then save the file and run this 
command:

sudo update-grub

Now you should reboot to check if it really works.
