Okay, so I'm not an idiot, but I feel like one. I have a SSD with Windows 10 already installed. All I want to do is make it compatible with my macbook pro. How do I do this? A link to a relevant site is fine, but a step by step walkthrough would be better. I've looked everywhere, but all of the sites I find want you to use VMs or reformat and install windows on the drive which it is already done... can I just skip all these prior steps and go from there?
