dual boot 2 hard disks (vista & ubuntu)

I have linux on disk 1 and vista on disk 2,

disk 2 has boot priority as i set in the bios,
i have grub on disk 1 but i wish to have it loaded from vistas bootloader?

any tips, I looked at the wiki but the options did not help me
Uninstall neogrub on neogrub tab, delete current linux entry, and then go to linux tab and add a new entry selecting the disk/partition ubuntu is on before checking that grub isn't installed to mbr. Reboot and assuming that disk 1 is enabled you should now get a second menu when the linux entry is selected with your linux entries.
