Grub2, while still fairly early in development to be included in a major distro, is a significant improvement over grub-legacy. One of the ways it excels is partition auto-detection. For example, it found and automatically chainloaded my OSX hackintosh partition. I would recommend reinstalling grub2 from a live CD. Please note that anytime you are reinstalling/trouble shooting boot issues, there is always a chance you could cause other issues. Here are the steps to required to reinstall grub2, from a live Ubuntu 10.04 CD:
(assuming you have already booted the live cd and opened the terminal): Check to make sure that Kubuntu is still detected as /dev/sda3, using this command: sudo fdisk -l Assuming it is, you will need to mount all of the appropriate partitions and filesystems: sudo mount /dev/sda3 /mnt sudo mount --bind /dev /mnt/dev sudo mount --bind /proc /mnt/proc Next you will need to chroot into your Kubuntu install we have just mounted: sudo chroot /mnt Now we will install grub2: grub-install /dev/sda If you receive any errors from that command, run this one instead: grub-install --recheck /dev/sda Now you can exit the chroot environment, unmount the filesystems, and reboot to a (hopefully) working dual boot. exit sudo umount /mnt/dev sudo umount /mnt/proc sudo umount /mnt sudo reboot If that does not work for you, or you would prefer to stick with grub-legacy for some reason, write back here, and we will find an alternate solution.
