If you're Mac Sierra users then you must notice that Apple has stripped the function to create Windows 10/8/7 bootable USB/DVD from ISO on Mac Sierra and Macbook air.

This will take several minutes to complete but your data should be copied and the flash drive will be bootable. You can use it install Windows 10 on any desired system.
