    Not sure I'm following you here.... What version of OS X is on the external hard drive assuming it's bootable?

    The best way to install Lion clean is from DVD or a USB flash drive. Also note that in order to purchase and download Lion from the Mac App store you need to be running Snow Leopard 10.6.6.

    If you have already downloaded Lion from the Mac App store and have it on a hard drive, it should work without harming any files that are already on the hard drive.

    yea i have the lion files in a seperate folder on my hard drive with other files, i guess my concern is just booting and installing from it messing up the other files
