Bootcamp will not recognise x64 Windows 7 ISO or Install Disc

Found the solution. Rename the extension from .ISO to .DMG

That's it! Simple and proper working solution without side effects, thank you!

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.

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.

None have worked, is there anyway I can get it back to the original .Plist file.? I did not backup my laptop before doing so (stupidly). Would the best option be just to restore my whole laptop?

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 was able to simply run the following to get Boot Camp Assistant working again after editing the .plist file.

sudo codesign -fs - /Applications/Utilities/Boot\ Camp\ Assistant.app

Boot Camp Assistant crashes because you've changed its contents, and thus the code's signature becomes invalid.

Almost right, you actually need to do the following:

sudo codesign -fs - /Applications/Utilities/Boot\ Camp\ Assistant.app/Contents/info.plist

Followed by:

sudo codesign -fs - /Applications/Utilities/Boot\ Camp\ Assistant.app

The first command signs the file which was modified, and the second command then re-sgins the whole application. This worked for me on a MBP 15,2.

Do not forget the --deep qualifier when signing the whole application.

Ah OK! It worked for me without the --deep but it could be the first step isn't required with the --deep qualifier. Cool, will check this out.
