Welcome to Ubuntu.
To update your grub you can simply replace 2.6.24-21 with 2.6.27-7 in each place it occurs. The title line is what's shown on the screen when you boot up. Other wise you can copy each set of five lines so you have access to the old kernel for For example:

title Ubuntu 8.04.1, kernel 2.6.24-21-generic
root (hd1,6)
kernel /boot/vmlinuz-2.6.24-21-generic root=UUID=ac4f091c-d379-475c-8f76-b6e9ca0b5865 ro quiet splash
initrd /boot/initrd.img-2.6.24-21-generic

title Ubuntu 8.10, kernel 2.6.27-7-generic
root (hd1,6)
kernel /boot/vmlinuz-2.6.27-7-generic root=UUID=ac4f091c-d379-475c-8f76-b6e9ca0b5865 ro quiet splash
initrd /boot/initrd.img-2.6.27-7-generic

boot with live cd ubuntu-8.10
sudo mkdir /mnt/ubuntu
sudo mount /dev/sdx /mnt/ubuntu
sudo chroot /mnt/ubuntu /bin/bash

here your commands should work.
edit menu.lst
or reinstall grub

replace the partition number with correct number for x

Yes, the version doesn't matter. You just need to get the system booted so that you can edit menu.lst.

i cant do the last step edit menu.lst
error "Edit" ..
then i try to find boot in my system , i find menu.lst then try to copy paste command from Kevbert.
i restarted it then error 15(file not found), i didnt have backup my oldkernel.

so what should I do???should i reinstall grub or do fresh install?

Try this from the Live CD:

sudo mount /dev/sdaX /mnt
gksudo gedit /mnt/boot/grub/menu.lst
And replace sdaX above with your Ubuntu partition. That should bring up your menu.lst, and you can add the entry that Kevbert suggested. Let us know how it goes.
