You'll have to use a 3rd party cloning app that is compatible with with macs (GPT) which is something of a rarity, I think Paragon has something like that. But beware, this can be a rather technical procedure, there are two hurdles here, first is the difference in hardware for Windows and secondly is the GPT partition table. I won't provide instructions for it because there are too many things that can go wrong, except saying that you should backup and that it's probably easier to install from scratch in bootcamp and migrate your data.
