recovery will do its own formatting. But those formats are not well enough most of the time. Why dont you do a low level format or use another 3rd party formatting software like dban and then go ahead with the installation with recovery disk if you decided to wipe everything off ? Recovery will do its own formatting regardless what you do. That would be my pick.
