In the new operating system OS X El Capitan you no longer need to have a USB drive to install Windows in Boot Camp mode. You can use the usual way with “Windows” in ISO format.
In the new OSes, Apple has changed the interface of the Boot Camp Assistant. Now the ISO image is a block with hard disk partitions placed on one screen. Before “the MacOS users” had to connect to computer USB-stick, then utility downloaded the installer from the ISO disk in the drive, and the driver required for the correct operation of Windows. In OS X El Capitan procedure simplified. It is enough to specify a Windows image and to choose the size of the partition on the hard drive.
Once Boot Camp Assistant finishes installing, the Mac will reboot and begin the Windows installation. This became possible due to the fact that the installation process is created on the disk for more partitions “OSXRESERVED” formatted in FAT32.
In OS X El Capitan used the Boot Camp assistant version 6.0. It is compatible with Mac release in 2012 and supports 64-bit version of Windows 10. The installation of downloaded versions of Windows 10 in ISO format support MacBook Air (mid 2012 and later), MacBook Pro (mid 2012 and later models, including models with Retina display), Mac mini (late 2012 and later), iMac (late 2012) and MacBook.
To find out whether Mac is compatible with this function, you need to “jump” menu, select “Utilities”, run the program “Boot Camp Assistant”, and click “Continue”. If there is a checkbox “Create setup disk Windows 7 or later”, so the user can use the installation images of Windows.
