Not yet. If your USB worked on one Mac, it should work on others. You can get a better deal on Amazon.

If you do not have Bootcamp installed yet, the BootCampHD variable may not exist.

Delete your BC partition only using BCA, nothing else. Reset SMC/NVRAM (or PRAM) twice. Run the same nvram command and post the output.

If you still see BootCampHD variable, then use the following command...

sudo nvram -d BootCampHD

Now try your BCA installation again.

Ran it twice and nothing came up, is this a good sign?

To be 110% certain, please run a SMC reset and NVRAM Reset. Boot back up, check again. If you prefer 7, try it first.

My suggestion is

Option 1.

1. Erase your Winisntall USB.

2. Remove the BC partition using BCA.

3. Burn your Windows ISO to a physical DVD.

4. Download drivers appropriate for your hardware from Boot Camp: System requirements for Microsoft Windows operating systems - Apple Support to a USB2 disk.

5. Connect a SuperDrive and the USB. Insert Windows DVD.

6. Run BCA without creating the USB, partite your internal disk, and try installation.

Option 2.

Install a clean copy of OSX on an external USB flash stick (16GB+) or more using OS X: Installing OS X on an external volume - Apple Support.

Reset SMC/PRAM.

Boot from this new OSX installation and try BCA on the internal drive.
