I have an early-2011 15" MBP 2.2ghz i7 with a 256GB SSD from Apple. I want to install a 2nd SSD (120GB OWC Mercury Electra 3G w/ Data Doubler) in my optibay and use that drive as a dedicated Boot Camp/Windows partition so that I can run some Windows-only video programs (3DS MAX, Touch Designer, etc.) on my MBP. I've done some homework on this, but after reading the Bootcamp installation guide and several forum posts, I'm confused over how to begin the process. First off, I'm thinking it would be best to make the optibay SSD a dedicated Bootcamp/Windows drive, so that, in the future, I can temporarily replace the optical drive if I need to. If I were to set up my primary and secondary SSD's as a continuous volume and put the Boot Camp/Windows partition on the primary drive, I'm afraid removing the optibay SSD would create big problems. Right? If I go this route (primary SSD - OSX / secondary SSD Boot Camp-Windows), I will have to install Windows on the secondary SSD in the following sequence (because Windows can only be installed from an internal optical drive to an internal hd): (according to http://forums.macrumors.com/showthread.php?t=1153513) 1. remove the primary SSD from the main hd bay, replace it with the secondary SSD 2. install (Bootcamp?)/Windows on the secondary SSD from the internal optical drive 3. remove the secondary SSD from the main hd bay, replace the primary SSD 4. remove the internal optical drive, replace it with the secondary SSD So this is where I'm missing a bit of key info that isn't addressed in the forum posts I've read: if the secondary drive is a brand new, unformatted SSD, can I just stick it in the main hd bay and start installing things on it? What do I install first? OSX, Boot Camp, Windows? Alternatively, do I need to format it and/or install OSX on it via an external enclosure before putting it in the main hd bay? I just don't have enough basic knowledge about how hd's and OS's work to understand how this should go.
