bought a new iMac pro and got a windows 10 key. Went to the Microsoft sight and downloaded the win 10 iso. I have left it in downloads and tried install. No good. Put it on a flash drive and as before after I I put the product key and get the ok it goes to the install screen. Then I get this. I’ve followed bootcamp and created partition 3 times now with no luck. The directions says bootcamp takes care of everything. Am I missing something?
