Create a bootable Windows 8.1 USB on a Mac running OSX Yosemite

This video will show you how to Create a bootable Windows 8.1 USB on a Mac running OSX Yosemite.

Hi All
Allot of 123myIT users have decided to take the plunge and upgrade their Mac OS X to Yosemite and I thought it might be a good idea to do a short video on how to create a bootable Windows 8.1 USB on a Mac running OSX Yosemite.
This video is mainly for people that want to be able to create a USB installer disk drive, so that they can install Windows on any computer whether it be a Mac or another brand. This method can also be used at a later date to reinstall Windows on the same Mac that you create the USB drive on.
So in the example in the video I created the USB on a early 2014 MacBook Air. In this process it also downloaded the Windows support software for this Mac hardware. This means it will run the boot camp installer after Windows gets installed. See the picture below.

So the If you want to check out the list of Windows support software or boot camp drives for your Mac a great place to start is the 123myIT boot camp drivers page here.

  3. Is it possible to do this on a late 2011 MacBook Pro running OS X Yosemite? BootCamp doesn’t give me the option to create an install disk. Let me know.

  4. hi,
    so ive downloaded the windows 8.1 iso file, 8gb usb connected, and both were automatically recognized by bootcamp, but as soon as i hit continue i keep getting the same message saying: ” Your bootable USB drive could not be created. Boot Camp only supports Windows 7 or later installation on this platform. Please use an ISO file for Windows 7 or later installation.”

    im using a yosemite running imac, and downloaded the iso file from your website “Windows 8.1 Blue”

  5. Is there a way to create a Windows bootable USB from an iMac?
    I don’t get that option to create a bootable USB while on Yosemite, but in previous versions of OS X there were workarounds which don’t work anymore.

  6. Hi! Thank you so much for the awesome tutorial, I’m stuck at the point where I have to install windows on drive 0 partition 4 boot camp, I formatted the drive, but I still could not proceed. It says that “windows cannot be installed to this disk. The selected disk has an MBR partition table. On EFI systems, windows can only be installed to GPT disks.” What should I do now?

  7. Hello,

    This has been really helpful so far. I am trying to download Windows 8.1 Pro Student on my 2013 Macbook Pro, and have been for a week. After trying to download it the first time, bootcamp kept crashing so I took it into Apple, and they showed me how to reinstall OSX. I got everything back up and I’ve had Yosemite since it came out. I did what you said and put the downloaded Windows file straight from their site into my documents folder after I changed the file to an iso (by just going in and changing it from .exe, to an .iso. It recognized it and my 16gb completely free usb drive. After watching this, I was actually able to get passed it saying that “… it only supports Windows 7 or later…” error message by putting it in the documents folder. But it kept stopping halfway through every time saying that there was an error copying the files, even thought the USB changed it’s name to WININSTALL. It won’t go further. I download the Windows Blue and tried that too, but again it didn’t work. I went back to try to do it the original way and I’m getting the Windows 7 or later error message again even though it’s still in the documents folder. I have a deadline for a project coming up and really need Windows on my mac. Thank you!!!

    • Hi Nicole
      Sorry to hear about the issues with your Mac.
      If you are not using Windows for games and its just to use some Windows Apps then another option might be to use VMware.
      Video here.
      Vmware
      Good luck

  8. Hi

    I am a little stuck at the moment, I can’t seem to find a solution that will work or possibly I have been doing it wrong.
    I have a Mid 2014 15 Inch Macbook Pro Retina Display, I upgraded everything through apple (CPU, 1TB SSD, Graphics Card)
    My problem is once I get to the point of partitioning the drive between OS X and Windows I get the error ‘The disk cannot be partitioned because some files cannot be moved.’
    I have tried verifying and repairing the disk but when I go to continue with bootcamp it says it cannot read the installation CD.. While I am using the USB.
    I am trying to install Windows 8.1 64bit which I downloaded on a PC and then created an iso image for. I now have it on my Mac, it was previously on my desktop but I saw you mention moving it to documents which I tried but I have still had the same result. Do you have any suggestions for me?

    Thanks in advance.

  9. 1. it never did complete in the end. it still said copying the files but it looks like all the files were copied.

    2. now i am trying to use the usb to boot windows back on a lenovo laptop. is there anything special I need to do? Im at the blue screen… do I use boot from usb fdd: , usb hdd: , usb cd: , ata hd: , atapi cd: , pci lan:

  10. Hi, Can I use a 100GB hard drive to make a bootable Windows 7 on my macbook pro? Or is it necessary to use a USB minimum of 4GB?

    Thanks in advance.

    Cheers,

    • Hi JayR
      Yes, you can use that. Just be aware tho it will wipe your drive clean. So make sure you don’t have any data on the drive when you do it. Otherwise you wil risk using those files.
      Cheers
