  1. Hi Matt,
    I purchased my Windows 8.1 online from the Microsoft store and only received a downloaded copy of this file “OSGS14-WindowsSetupBox-32bitand64bit-English-4141408.exe”. Is it possible to make an ISO from this using Disk Utility so I can use it with Bootcamp Assistant to make the bootable USB? I don’t have access to a PC so I can’t run that .exe file to create an installation disk. Any suggestion? Thank you for your help!

  2. Hey Matt,

    Same problem as above but I do NOT own a PC. Is there anyway to create that ISO file from the download link on my Mac?

  3. I tried completing these steps, and for the most part it worked but when I tried opening up the ISO file it gave me some error message about not being able to detect, image. I think something maybe wrong with my portable DVD player on my MacBook pro. I was wondering if I could turn my windows 8.1 installation disc into an iso file on my PC and then add the iso file to a USB for my mac to read? Does it work that way, or do I need the ISO on my mac?

  4. I get this error “Boot camp supports windows 7 or later installation on this platform. please use ISO file for windows 7 or later version”

    I am on yosemite 10.10.5 Mac , did follow your steps for ISO by using my WIN8 PRO and then i did execute steps for bootcamp assistant i got the error “Boot camp supports windows 7 or later installation on this platform. please use ISO file for windows 7 or later version”

    could you let me know what is missing

    I do have OEM product key for windows 8 pro aand would like to upgrade for win10 on mac

    is this possible ?
