If you cannot go to normal grub mode, do this....

grub rescue> set prefix=(hd0,x)/boot/grub
grub rescue> insmod (hd0,x)/boot/grub/normal.mod
rescue:grub> normal


If still fails...boot up live cd...

at terminal...
sudo grub-setup -d /media/{kubuntu9.10partition}/boot/grub /dev/sda

substitute /media/{kubuntu9.10partition} with actual partition :)

If you get error message,(mapping fails), do this..

sudo grub-setup -d /media/{kubuntu9.10partition}/boot/grub -m 
/media/{kubuntu9.10partition}/boot/grub/device.map /dev/sda
