1. Did you modify Bootcamp info.plist?
2. Are you using EFI Boot?
3. There is no Mid-2012 iMac. Is this a Late 2012 iMac?

1. Your specific model does not need Bootcamp info.plist modifications. It supports both USB and DVD installers.
2. Do not use EFI Boot. Your Mac is a preUEFI Mac and you will face more issues later.
3. Use BCA and do not interrupt the installation till you have to pick a partition for Windows destination.

1) I changed Bootcamp info.plist because it didn't load. Than I found solution on youtube. So I just take PRE from this line: <key>PreUSBBootSupportedModels</key>
Than I did small change on terminal: sudo codesign -fs - /Applications/Utilities/Boot\ Camp\ Assistant.app

2) If I would't use EFI, so what should I use than?

3) What is BCA mean? Thanks for the advise

Please, write step by step instructions if it possible. Thank you

1. There is no need for it. It causes other problems. This is from my mid-2012 MBP.

2. BCA will create appropriate Hybrid MBR and start the installer. Do not use Alt and select EFI Boot.

3. BCA = Bootcamp Assistant.

1. Please disconnect all external storage. You should only have the USB with the Windows installer.
2. Do not use any USB hubs.
3. Can you verify that your USB installer is a USB2 flash drive. Here is an example.
