I take it your grub is the old grub, ie, grub-legacy.
At grub prompt, grub>, type
root (hd0,x-1)
kernel /boot/vmlinuz-2.6.31-10-generic root=/dev/sdax ro quiet
initrd /boot/initrd.img-2.6.31-10-generic
boot


Important note: I am at hardy, can't remember what's the karmic kernel 
is at now.
o  Substitute "2.6.31-10" with what you have.
o  (hd0,x-1) and sdax --  x is a real number for your karmic partition.

Of course once in Karmic, please update to grub2 and install/set to sda.

Good luck.
