Hey guys need a couple of things helped. Having a massive brain blank. I am tossing up a fresh install or cloning/migrating my boot drive. Best way to go about that? Then, with my current storage hard drives, how do I re-index them with a different letter if they have data on it already. I remember there being a video and can't find it. Thanks, for the help ahead of time. Apologies if this has been answered. Couldn't find a thread search bar/option to search before asking.
