    I'm wondering which one is the best way to get a fresh and clean install of Mac OS X Lion.

    What have you tried and what have worked best?

    -Snow Leopard + 10.6.8 + Lion
    -Install Lion and then clean install from Recovery HD
    -Install with bootable image of Lion from DVD, USB...

    I booted the usb image on my son's mbp to prove that it worked. I looked for migration options but none showed up. Perhaps they might have showed up after Lion was installed but by then his hdd may have already been wiped and reformatted for lion. Clearly the usb is intended for a fresh install and appears to not offer the same options the SL dvd once offered. For this reason we used install os x just to make sure all his files and settings came over.

    The reason I picked the third choice in your poll is it seems like the best way to avoid bring any 10.6 settings, however short lived, over to Lion.

    I used the USB stick method. The fastest an easiest since you don't have to install and download Lion twice. Also good to have the media for future use.

    I agree

    Before a clean install, I would also have a CCC backup as well as a time machine backup in the event things go wrong/need your data

    I am creating a USB, with two partitions; one with the bootable disc of Lion; and the other one with my essentials apps.

    But, I have thinking...with this method, may we lose some Snow Leopard features, like Apple Hardware Test, or some apps that included Snow Leopard original release?

    The hardware tests are still there, Xcode is not included though

    But Xcode wasn't also included with Snow Leopard, I think.

    So, I will have exactly the same if I do Lion from USB instead Snow + 10.6.8 + Lion?
