I just got a new SSD to use as my new boot disc. I also got Windows 8.1. I already have Windows 7 installed on my Hard-drive. What would be the process of using both drives at the same time? Will i need to install Windows 8.1 on my hard-drive as well as my SSD? Or can i just switch my SSD to my boot disc, install windows 8.1 on it, and leave my other drive alone? Also, what 'option' should my drives be in? I have no clue what RAID is, is that what i need?
