How do you dual-boot Vista and Ubuntu if you have ubuntu first?

Possibly you have some partitions set up.
I understand you like that:
On startup you want to either select Ubuntu or Vista.

Have you allready installed both Vista and Ubuntu.
And on startup:
Do you see a thing called 'GRUB'?

You'll install vista, which will simply kill grub because vista thinks that it is more important, then you will have to boot a live cd and reinstall grub:

sudo grub
find /boot/grub/stage2
find /grub/stage2 #(if you are using a separate boot partition)

you will get something like hdx,y

root (hdx,y)
setup (hdx)# or (hdx,y) if you want to install grub to the MBR of the parition instead of the MBR of the disk
sudo update-grub
