Q: Bootcamp will not recognise x64 Windows 7 ISO or Install Disc
27" iMac late 2012
I've tried using both my Windows 7 ISO to create a bootable drive, and also attempted using a disc burnt using disc utility, but I keep encountering the following message with Bootcamp. My Windows 7 install disc is a mixed x32 and x64 (I would obviously choose x64 bit when running windows install later) But is displaying the following image?
I used the same windows disc to install the x64 bit version on my 2011 27" with no problems, I've also tried to use another Windows 7 install disc but it's giving the same error...
"Boot Camp only supports 64-bit Windows installation on this platform. Please use a ISO file for 64-bit Windows installation."
Any ideas how I could fix this?
iMac, OS X Mountain Lion (10.8.2)

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