This is the kind of task I would test on spares before going anywhere near my main setup. Yes - here be dragons indeed.

Why Fusion Drives & Windows Don't Mix

I would suggest you post a new question regarding how to install Windows without using the Boot Camp Assistant. I absolutely disagree with the close reason for this - there is a specific and quantifiable reason as to why this problem affects iMacs with 3TB fusion drives.
