Hello! I am looking to install Windows 10 on an external drive to avoid taking up space on my internal Flash drive on my iMac (27-inch, Late 2013). I know Windows cannot boot off USB (at least not without some major tinkering), so Thunderbolt is the way to go. Can anyone who's done just that comment on how well it works and any things to look out for? Does Bootcamp assistant allow installing to an external drive? Also, if anyone can recommend an affordable thunderbolt 1 or 2 enclosure available in Canada (or US store that ships here), I'd be thankful.
