macbook leopard failed install

[chris200x9]

Hi I was installing leopard on a core duo macbook running 10.4.11 and I put in the leopard install disk, I chose upgrade and the install just barely started and then said "install failed". After this I immediately booted intoo 10.4.11 to see if it was alright, it was. When I try to install again I get to the point where it says select a destination, I choose the harddrive and when I select it and hit continue a dialog box pops up that says your chosen instalation type cannot be done. I then hit option and a dialog box pops up again that says the destanation volume must be completly earased and the new Mac OS X will be installed.


what's wrong? Is there anything I can do about this? Do I need to back up and erase and if so what is th best way/ back up program? Also I don't have an external hardrive but do have another macbook next to me with enough harddrive space to fit my back up on.

if I create a disk image with carbon copy cloner will it just copy my files a.k.a data and not my system folders and if I do that can I easily keep all my prefrences once I upgrade

what I think I mean is can I back up the home folder and then clean install and replace the new home folder with the old one?

Very strick about a GUID partition on the Intel machines, if you use disk utility to check the partition scheme and it is GUID then it may be another issue...
