How to create a bootable Windows 7 8 USB on a Mac

This video will show you how to create a bootable Windows 7 8 USB on a Mac.
You can use the bootcamp assistant to create a bootable Windows 7 8 USB on a Mac. However the option may not be highlighted in your bootcamp assistant.
To make the option appear you can try the following steps.

Step 1. Click on Go then Utilities. Find the Bootcamp assistant, right click on it and go to Show package contents and then go into the contents folder.

Step 2.Copy the info.plist file to the desktop and make a backup copy of it and open it.

Step 3. Find the line which says PreUSBbootsupportmodels and remove the Pre from the line. Try running the bootcamp assistant again and this time you should have the Create a Windows 7 or later install disc option.

Step 4 Copy the info.plist back to the contents directory. And start the bootcamp assistant again and see if the Create Bootable USB Drive for Windows installation comes up. If not try this next step.

Step 5 Change the USBbootsupportedmodels in the info.plist file.
You can find the model on the Mac that you are using by going into the Apple menu then click on About This Mac and then click on More info. Next click on System report and under Hardware Overview look up Model Identifier.
In the example in the video my MacBook model was MacBook7,1.
In the info.plist file I had to change the USB supported models to my MacBook model so that I could create a Windows USB on a Mac.

    help me?????how create bootable windows 8

  3. HI Admin,

    You’re using only 1GB flash drive right? and then i used 4GB but then the boot camp says ‘Your bootable USB drive couldn’t be created ‘There is not enough space available on the disk’ Please help me with this.

    Thank you so much!

  4. I downloaded the windows 8.1 64 bit from your website and when its finished installing I go to boot camp assist and it says that my platform only supports 64 bit, which is what i downloaded. Do you have any suggestions on how I can fix this?

    • Hi Seanna
      That’s weird you have done the right thing? It should work.
      What version of OS X are you using ? What version of Mac hardware are you using ?

      • Win 8.1 comes in a combined 32 and 64 bit single version when downloaded from Windows online store. DO NOT BUY ONLINE! Mac will ONLY allow a 64 bit. GO TO THE WINDOWS RETAIL STORE AND PURCHASE the physical installation discs. The package comes with two discs, one 32bit and one 64bit. That is the only way to get the installation files separated (only way I could figure it out).

  5. I followed all of your steps but when I got to the Windows setup I received an error message “windows cannot be installed to the disk. The selected disk has an MBR partition table. On EFI systems, Windows can only be installed to GPT disks. Windows cannot be installed to this hard disk space. Windows must be installed to a partition formatted as NTFS”

    When I tried using a different ISO file, (not the one on your site) I could not get the image to boot at start up. Any advice? Thanks!

  6. Hi i need windows 7 32-bit image , i have some application that working with windows 7 32-bit , i couldn’t find windows 7 32-bit link to download here ….can i have it please? i will install it with bootcamp…

  7. “Your bootable drive could not be created. An error occurred while copying the Windows installation files.” What should I do? Help pls

  8. For people who got bootcamp crashed after modified the info.plist file just use this step.

    1. Make sure you install xCode from appstore
    2. After you modified the Info.Plist opent the terimnal and run this comman
    3. sudo codesign -fs – /Applications/Utilities/Boot\ Camp\
    4. Voila after that you can use your bootcamp again.

    PS: Before you do any modification on .app files, make sure to always backup it to other folder incase you facing error like this.

    Hope it’s help.


      • Hi Cham
        Yes, add the line back and it should fix that issue.
        The process is the same you just need to find the correct line to remove.

        Try this one maybe.
        I have OS X 10.10, I found that you need some extra steps after updating the info.plist file and copy it back to the folder:
        1. Open terminal and type (without quotations): “sudo codesign -fs – /Applications/Utilities/Boot\ Camp\”
        2. Type your password
        3. It may or may not require additional app (it will ask you if you want to download it)
        4. If you had to download the app, type the command from step 1 again once you finish the download.
        5. You should be able to open and the option will display.

        On the YouTube page from a guy called CaMaVi01 it worked for him.

        Good luck

  9. when i bought the software form microsoft it came as a .exe file rather than a .iso, so bootcamp won’t let me create the usb, what do i do?

  10. Having a problem installing Windows.

    So I have a Macbook Pro late 2008 and an ISO of Windows 7 x64.

    My Disk-Drive doesn’t work, I’ve replaced it with an SSD.

    I’ve changed all necessary data in the Info.plist from Bootcamp 5 and created a USB-Stick with Windows.

    The problem appears, when the system restarts: no windows installation begins, there is just an Apple-logo for a long long long time (until I turn my Macbook off). After starting it again, black screen with no bootable device appears and when I hold alt/options, my USB-Drive won’t show up.

    Any suggestions? Would appreciate. My last Windows 7 x32 which I’ve installed about 3 years ago, worked fine.

    • HI Bob
      Try holding down the alt option key when starting the Mac, make sure the usb is out at this stage. Then once you see the Mac boot menu plug in the USB and does it come up?
      Can you test the USB on another USB port or another Mac?
      Can you test the USB on another PC?
      It sounds to me like the USB may not be setup correctly.

    • Hi Reinier
      The problem comes from upgrading to Yosemite from an earlier version of OS X.
      If you go to that video directly on YouTube there is a few people that have been able to fix the issue in the comments section below the video.
      Have a scroll down and you can get the fix from there.
      Good luck

  17. Hi,
    I have a iMac mid 2010 with High Sierra version 10.13.6 and also I have installed a SSD hard drive on primary sata port after removing the DVD drive. So I have SSD as my primary hard drive where OSx is installed and now I want to install Windows 7 or 8.1 on secondary hard drive which originally came with the iMac. But somehow I am unable to do so as Windows (7, 8.1 & 10) installation is not able to install it (not able to recognize the partition) on the secondary hard drive.
    Used boot camp 4.0 to make the Windows installation USB.
    Though I have tried to list all the details but in case you require more information please let me know.
    Could you help me?
