Hello, Just recently purchased the new iMac and tried to install Windows. There was a problem on the Windows side and the installation crashed leaving a partition that could no longer be removed. Used apple support to try and remove it and they said the best thing to do was to recreate the fusion drive. A strange thing seems to have happened though where I now have two Macintosh HD. Is there anyway to remove the other one as this doesn't look like a thing that should be happening. Thanks!
