How to "Create a Windows 7 install disk" on Mountian Lion w/Bootcamp 5
It's basically the same way you create one with previous Bootcamp & OS verisons.
Finder -> Applications -> Utilities -> Select Bootcamp -> Show Package Contents
Open "Info.plist"
Scroll until you see whats listed below.
<key>PreUSBBootSupportedModels</key>
<array>
<string>MacBook7,1</string>
<string>MacBookAir3,2</string>
<string>MacBookPro8,3</string>
<string>MacPro5,1</string>
<string>Macmini4,1</string>
<string>iMac12,2</string>
<string>iMac11,2</string>
</array>
Remove the "Pre" in "PreUSBBootSupportedModels"
Then it will ask if you want to make a copy of the file, click yes.
Now in the new "plist" file cut out "MacBook7,1" in the top line and replace with your Model Identifier (Can be found in "System Information" under "Hardware Overview")
Save this file as "Info.plist"
After save the old "Info.plist" file as "Old.Info.plist" and move to the trash can (May as for log in info to do so)
Then after that file is in the trash move the NEW "Info.plist" (The one you edited) to the Bootcamp Content folder in place of the other one.
If everything is done right you should now be able to "select/disselect" the "Create a Windows 7 install disk" in bootcamp.
You're welcome,
