Thank you again. So with the LE, I don't need to download any drives from the net?

Regarding partitioning, I'm really sorry, but I am a bit lost. I just need you clarify one or two terms.

'You don't need to "clean" anything. Just reparation the drive when you install the OS.' Do you mean that I don't have to uninstall Tiger (which is what I meant by "Clean") and all I have to do is simply run a "repair permissions" task in disk utilities once Lion is on the other partition?

"And to be clear you cannot format/repartition your running boot partition" I don't understand what this means, so sorry... "A faster way is to use an external scratch drive. Use Carbon Copy cloner to clone the existing install. Boot off that cloned disk. Then partition the internal drive and you should be able to clone back the external drive and then install the other OS X version on the unused partition." Oh dear, did I say one or two terms... I am lost.
