A:

After both resets without any storage, choose the last option, Install... and partition and test. If it fails, do not delete the partitions.

    Did you do the following steps? On your iMac, this should have both Drive0 and Drive1 and you need to choose Drive1:Partition 4, since you have a Fusion drive.

    Please try the partitioning again and leave the BC/Windows partition. We should check the partitions before we clean up and figure out the issue for the next attempt.

     

    Before you retry, can you disconnect all external storage and run the following two procedures?

    If you did not remove the BC/Windows partition, can you post the output of the

     

    diskutil list

    diskutil cs list

     

    Did you run the two resets before retrying the partitioning?

    Just to clarify, are you able to install Windows without any issues and does all your Apple-specific hardware work properly? If yes, please back up OSX, Windows and create a Windows System Restore point.
