    I have a late '08 Macbook aluminum unibody with Snow Leopard installed. I want to upgrade my HDD, which is only 250 GB, and the OS to Lion.

    What would be the process to clean install on an entirely new HDD? Correct me if I'm wrong...

    1. Download Lion from the app store and make a bootable USB or DVD.
    2. Install new HDD and boot from the USB or DVD by holding down the option key

    Anybody successful with this? I don't see any reason why I'd have to install Snow Leopard first.

    That'll work.

    You need to run disk utility to partition the new disk prior to installation.

    I thought there was a sequence during the installation where you select the drive and partition it. No?

    No.

    Lion assumes it's being installed on top of an existing OS X installation. It'll ask you to select from active partitions on the disk but doesn't automatically setup an empty/blank drive.

    Just pick Disk Utility from the menu at the top to partition the new drive then continue with the installation assistant.
