MacOS – How to install Windows 10 64-bit in El Capitan Boot Camp

bootcampmacoswindows

I'm running OS X El Capitan 10.11.1 on an early 2015 13-inch Retina MacBook Pro (MacBookPro12,1) with Boot Camp Assistant 6.0.0 (519).

I have downloaded Win10_EnglishInternational_x64.iso from Microsoft.

When I select this ISO and click Install in Boot Camp Assistent I am presented with the message below and I'm not able to continue.

Need 64-bit Windows 8 or later ISO file.

Boot Camp only supports 64-bit Windows 8 or later installation on this platform. Please use an ISO file for 64-bit Windows 8 or later installation.

What do I need to do/change/download for Boot Camp Assistant to accept Microsoft's official Windows 10 ISO as a valid "64-bit Windows 8 or later ISO file"

I also tried en_windows_10_multiple_editions_x64_dvd_6846432.iso that I can download from MSDN as a subscriber. This ISO file is also not accepted by Boot Camp Assistant.

I think because you download an iso and mounted it (open it) and that silly error pop out. I just unmount and it's work
