I'm planning to replace the optical drive in my MacBook Pro 9,1 (mid-2012, non-retina) with an SSD and make the two internal drives into a fusion drive, and I know that creating a boot camp partition on a Mac without an optical drive can be a challenge. So I want to create my boot camp partition before I create my fusion drive.
I couldn't find an answer to this in my googling. I know that you can create a Boot Camp partition if you already have a fusion drive.
Can I create a fusion drive using an HDD that already has a boot camp partition on it?
