Sorry Noob, didn't see the sentence just above, it was sandwiched 
between the other quoted parts without spaces in between. There is no 
need to delete any of these. Leave it alone. In Colin's example, cut

karmic and put above all of lucid's entries. No menuentry was killed in 
the making of this grub.cfg :)
