Read http://ubuntuforums.org/showthread.php?t=224351.I think your ubuntu is on (hd0,2) because grub count from 0 not from 1.

As zvacet said grub uses a different nomenglature than fdisk (grub = fdisk -1) to identy partitions. It should be:
 $ sudo grub

1. grub> find /boot/grub/stage
    ** Search the root partition (/):
2. grub> root (hd0,2)
    ** hd0,2 ; or the result of the first step (find)
3. grub> setup (hd0)
4. grub> quit
