Your 2014 Mac should have three options in - Create, Download and Install (or Remove).


  • Create+Download create the USB2 Flash drive installer, which needs to be done only once.
  • Install partitions and installs Windows using the USB2 Installer.
  • Remove removes an existing installation.


What is the name of the W10 ISO file and its MD5sum?

Run BC Assistant and Remove/Restore the current Windows<<< how should i do this ? i have to remove and install windows on flash drive again ? or how do i restore it ? when i go to bootcamp it has only one option to delete partition after unsuccessful installation.
