You need support software (drivers) installed with Boot Camp to use Windows 10. This software is automatically downloaded when you use Boot Camp Assistant. Boot Camp supports 64-bit versions of Windows 10 Home and Windows 10 Pro when used with a supported Mac.
Windows 10 is available from Microsoft as an ISO file and a USB flash drive. You need an ISO file of the 64-bit version of the Windows 10 installer to install Windows on your Mac. If you purchased the USB flash drive version you can download an ISO from Microsoft and use the Windows installation key that came with your flash drive. If you're installing Windows for the first time, make sure the Windows installer you're using is for a full installation (not an upgrade installer).
How to install Windows on your Mac with Boot Camp
Boot Camp helps you install Microsoft Windows on your Mac. After you install, restart your Mac to switch between macOS and Windows.
Before you begin, make sure you have everything you need:
An Intel-based Mac
A Microsoft Windows installation media or disk image (ISO) containing a 64-bit version of Microsoft Windows 8 or later, Home or Pro editions.* If you're installing Windows for the first time, use a full installation (not an upgrade) disc or disk image.
An Apple keyboard, mouse, or trackpad, or a USB keyboard and mouse
At least 55GB of free disk space on your startup drive
A blank 16GB or larger USB 2 flash drive. (If you have one of these Mac models, you don't need a flash drive)
