Triple booting Vista 7 ubuntu 9.10

[Henr]

Hi,

I'd like to edit the grub in my new ubuntu 9.10 to be able to choose at startup among vista windows 7 and ubuntu 9.10

currently I'm only able to choose either Windows 7 loader (which later gives me the option to choose between vista or 7) & ubuntu

thanks in advance!

You only need to run 'sudo grub-mkconfig -o /boot/grub/grub.cfg', and GRUB 2 should detect all of your operating systems and add them to the boot menu automatically.

sudo grub-mkconfig -o /boot/grub/grub.cfg
