windows server 2016 via boot camp?

And by the way in terms on Windows admin tasks with Server 2016 you will need to split this install.wim file down for ANY UEFI installations you plan on doing, even if its a Windows based system. If you don't care about UEFI then any standard flash drive formatted as NTFS and set to bootable will suffice will the files as they come on the ISO.

This technique also worked for me. Remember to copy all files from the ISO after splitting install.wim.

I had tons of issues after installing MacOS, its new bootcamp software has tons of limitations and issues, the only way I have found (and is actually easier than old workarounds) to make it work is to make a Server 2016 ISO without any install.wim (many ways to do this, for those stuck you can use a file extraction program of your choice [i.e. 7zip, winrar] to unpack the msft iso, then remake the iso with the program of choice [I use imgburn] without the install.wim). On reboot attach a usb stick with the proper msft iso loaded, the install will run from the source wim on the flash drive. Split wims and other methods all kept failing with the new bootcamp version in MacOS (10.12 Sierra w/e lol)
