Buy Mac OS X 10.7 and install on an empty drive I want to upgrade my old MacBook 3.1 late 2007 by replacing the hard drive with a SSD (Crucial MX100) and updating Mac OS X from 10.5 (Leopard) to 10.7 (Lion), which is the latest compatible version with it, as I know.

My question is about Mac OS X 10.7, I plan to buy it on the Apple website, and I was wondering if I will be able to install 10.7 on a new drive, after reading this:


  System Requirements
  Mac OS X Snow Leopard v10.6.6 or later (v10.6.8 recommended)


It suggests that you can only install it as an update on an existing OS, and not on an empty drive.
Follow these steps


Create a USB key for setup with DiskMaker X.
Replace HD by SSD (keep HD safe)
Boot on USB key newly created.
Format SSD with Disk utility (already in the top menu on the USB key)
Clean Install on the new SSD!
