I installed 10.04 alongside the old version and now want to un-install it.Do I just delete it using Disk Utility? Or can I do it another way?

You can delete that partition with Ubuntu live CD.After that you will probably need to reinstall grub. (https://help.ubuntu.com/community/Grub2#Reinstalling from LiveCD)

Yeah, you would have to reinstall Grub which isnt all that hard. Im not sure if this will work, but I would try reinstalling Grub to your current partition before you restart or make any changes.

I deleted the old kernels and headers thru synaptic but the new os was still there.also which cd to use,the old one or the new one? Then can i delete the partitions using disk utility?

Wait, are you saying you want to delete the lucid partition or your old one?

Boot from a live cd. Doesnt matter which one. And delete the lucid partition using either gparted or disk utility. You may not have to reinatall grub, buy Im not sure.

It is slightly easier to reinstall grub from the system you want to keep, but you can do it from a liveCD. The grub in the MBR will be the last install unless you specified otherwise during the install.

reinstall from working system - first find Ubuntu drive:
sudo fdisk -l
if it's "/dev/sda" then just run:
sudo grub-install /dev/sda
If that returns any errors run:
sudo grub-install --recheck /dev/sda
sudo update-grub
