Bootcamp will not recognise x64 Windows 7 ISO or Install Disc

Hello,

I see a lot of you guys struggling to get it to work.

I received the error "Bootcamp will not recognise x64 Windows 7" as well.

So it frustrated me and started searching on the web for solutions.

And I had read someone saying "unmounting the image" solved it for them.

Anyways, straight to the point.

1. Go to Applications/Utilities
2. Open Disk Utility and keep it open
3. Open Bootcamp, check the top option and leave the two underneath unchecked
4. Click continue and then select your Windows 7 ISO file
5. If it failed again, go to Disk Utility
6. Check if you can see the Disk Images tab under the External tab
7. If you can see images that are called DVD eject those
8. If you can see "Apple write" or something, ejecting these did the trick for me
9. Select one of the images "Apple write" and go on file and hit eject there
10. Eject all of them
11. Go back to Bootcamp
12. Select your Windows 7 ISO once again and that should do the trick for you as well.

Please keep in mind that I'm using El Capitan.

You need a 64-bit only Windows 7 ISO. Mixed versions aren't compatible with the Late 2012 iMac (I suppose that they contain 32-bit files that Boot Camp detects, refusing to use that file). Download a 64-bit only Windows 7 ISO and it should work correctly

I had the same problem, and found the solution on MacRumours, posted by one "falkas", to whom all credit is due. I tried it, and it worked first time, like a charm.

It is possible to use the Windows 7 ISO with both x86 and x64 on the same install file. Bootcamp 5 will see this as a x86 install file though and won't allow it to continue. To fix this just follow these steps.

1. Open a Finder window.

2. Navigate to Applications>Utilities

3. Control Click or Right Click on Boot Camp Assistant and select "Show Package Contents"

4. Open the Contents folder

5. Drag the file "info.plist" to your desktop (I also recommend saving it in another place as well in case you want to revert to the original)

6. Open info.plist on your desktop with a text editor

7. Find the field labeled as below:

<key>32BitSupportedModels</key>

<array>

<string>MacBook7,1</string>

<string>MacBookAir5,2</string>

<string>MacBookPro10,1</string>

<string>MacPro5,1</string>

<string>Macmini5,3</string>

<string>iMac12,2</string>

</array>

8. Time to find what your Mac is. Click the Apple in the top left hand corner and select About This Mac

-Click More Info...

-Click System Report...

-Under Hardware Overview, look for Model Identifier and copy it

9. With your Mac's Identifier copied, go back to your open info.plist file create a string at the TOP of the entries. So if your Mac identifier was "iMac13,2" then it would look like this:

<key>32BitSupportedModels</key>

<array>

<string>iMac13,2</string>

<string>MacBook7,1</string>

<string>MacBookAir5,2</string>

<string>MacBookPro10,1</string>

<string>MacPro5,1</string>

<string>Macmini5,3</string>

<string>iMac12,2</string>

</array>

10. Save and close info.plist. Drag info.plist back into the Contents folder and select replace. (You may have to authenticate and enter your admin password).

11. Start Bootcamp and it should allow you to use your Disk/USB with both versions. I wouldn't recommend installing the x86 (32 bit) version of Windows 7, but this will allow you to get to the point of the installation to select x64 (64 bit) if you have an ISO file with both 32 bit and 64 bit combined. Hope this helps.

Bootcamp will not open anymore, how can I fix the issue??

If you modified Bootcamp info.plist and tried the codesign method, try using --deep qualifier. Please see https://developer.apple.com/library/mac/documentation/Darwin/Reference/ManPages/ man1/codesign.1.html for details.

Please re-install OSX using OS X: About OS X Recovery - Apple Support. Please take a new backup before yo re-install OSX. OSX Re-install does not modify any other files, but it is better to be extra cautious with a fresh backup.

I have tried using this method explained by Akominatus, however when you get to step 9.

9. With your Mac's Identifier copied, go back to your open info.plist file create a string at the TOP of the entries. So if your Mac identifier was "iMac13,2" then it would look like this:

The info.plist file is locked and you cannot make changes to it.

error message

You don't own the file "Info.plist" and dont have permission to write to it.

You can duplicate this document and edit the duplicate. Only the duplicate will unclude your changes.

The duplicate does not save as .plist as it is in text edit.

This is getting rather confusing because now we are in another topic of editing locked .plist documents.

I'm not sure what is going on but I am running a new mini with no changes made to it and the error message comes up where as I do not see other people running into this .plist problem.

Any advice to get past step 9?

You need to stop the Boot Camp Assistant which might be running (assuming you are part way through the setup process). I had the same issue until I realized it was running.

You will also need to authenticate the new version of info.plist when you save it back to the contents folder.

Akominatus i tried what you have mention but after that my boot camp stop working so i had to revet back the info file any other solution or can you suggest where we are going wrong ..

Thank you

The problesm with this "fix" is that it will UNFIX your Bootcamp assistant because you do not have the code signature/ right to edit this Plist. If yo do edit it BootCamp assistant will crash on you over and over and over again until ..like me you happen to be smart enough /luck enough to have created a time machine back up that can restore the original file. A copy of the file you make WILL NOT work ...it must be untouched.

I agree, messing up with the info.plist enables to start the windowns install; but for me it stopped in the middle of the installation afterwards; so it is not a working solution (I tried on a MBA 2013 and a MBP 2013)

Solution was to download a x64 ISO (recognized by bootcamp without a problem) and then follow the bootcamp guide.

I had a similar issue. For whatever reason if I have the windows .iso mounted, I receive this message. If I unmount / eject the .iso before running bootcamp, I can proceed without issue.

Hope this helps someone.

There is a way around this. But it *****. You have to re install osx. Also you can't customize your partition size. You need to create a osx disk of flash drive. Before you install go into disk utility on osx install disk select 2 partitions. Install osx on one. Then put in your windows CD hold down alt boot from window install drive. Then format harddrive before install. It still may say "windows cannot be installed on this drive" just restart hold down alt and try again. It always work for me. Then install boot camp drivers and you'll be all right. I hope this helps.

use "dd" utility.

find your flash device from terminal:

# diskutil list

unmout flash drive:

# diskutil unmountDisk /dev/disk[X]

after it using this example command:
# sudo dd if=image.iso of=/dev/disk[x]

EricIsaac had EXACTLY the right solution. Once I unmounted the disk, Boot Camp Assistant stopped flashing me the "Boot Camp only supports 64-bit Windows installation on this platform. Please use a ISO file for 64-bit Windows installation." and started copying the file.

Dear All, solution is just there, you need to unmount windows iso from disk utility, I had the problem with windows 10 and macpro11,1.
