in another thread following solution was given:
"A very simple solution: make sure the ISO file is not mounted when running the Boot Camp Assistant!"

I got it. The solution was to un-mount the ISO file.
You would think that Apple would set up Boot Camp to do that automaticly.

we very often oversee the little obvious things, glad it solved it for you.

Make sure that the Windows ISO is unmounted.
To unmount: Open "Disk Utility" and under the drivers in the left sidebar you will see the windows iso. Right click on it and select "Unmount".
If iso file is still there, right click and simply press "Delete".

The disk “Win7.iso” could not be unmounted.
Make sure that all applications and files are closed on this disk.
What to do know?!

- Open "Disk Utility"
- On the left side of programm, choose file with file extension ".iso"
- Pull out all files with extension ".iso" (remove)
- Close utility

I have the ISO stored on a hard drive, when I used the ISO (Windows 7 x64) I get the same error as above but my disks in disk utility are unmounted, would it be the hard drive which is messing up? Any help would be greatly appreciated.

Same. I have tried everything - Switching Flashdrives (8G, 16G and 32G), Unmounting the iso file in Disk Utility, ect.
I have a brand new (less than a week old) imac that doesn't have a DVD drive so I can't burn the iso to a dvd and install this way.. Please help, I've been at this for days and am lost.

What do you mean un-mount the ISO File, sorry for the question but can someone tell me how to do this?, It would really be helpful.

I don't get the error any more. I just plugged in my 8 GB USB drive (Not containing the iso file or anything else, FAT 32 formatted). Checked the first box, installing windows 7 with an iso file. Chosed the path to the iso file, which was not on the USB drive but in my download folder. Even though is says it will format the data on the drive chosen, it formatted my USB and is now copying the windows files to my USB.
Hope this helps.
