How to install Windows 10 on Mac To
install Windows, use Boot Camp Assistant, which is included
with your Mac.
1. Check your Secure Boot setting Learn
how to check your Secure Boot setting. The default Secure
Boot setting is Full Security. If you changed it to No
Security, change it back to Full Security before installing
Windows. After installing Windows, you can use any Secure
Boot setting without affecting your ability to start up from
Windows.
2. Use Boot Camp Assistant to create a
Windows partition Open Boot Camp Assistant, which is in the
Utilities folder of your Applications folder. Follow the
onscreen instructions.
If you're asked to insert a USB drive,
plug your USB flash drive into your Mac. Boot Camp Assistant
will use it to create a bootable USB drive for Windows
installation. When Boot Camp Assistant asks you to set the
size of the Windows partition, remember the minimum
storage-space requirements in the previous section. Set a
partition size that meets your needs, because you can't
change its size later. 3. Format the Windows (BOOTCAMP)
partition When Boot Camp Assistant finishes, your Mac
restarts to the Windows installer. If the installer asks
where to install Windows, select the BOOTCAMP partition and
click Format. In most cases, the installer selects and
formats the BOOTCAMP partition automatically.
4. Install Windows Unplug any external
devices that aren't necessary during installation. Then
click Next and follow the onscreen instructions to begin
installing Windows.
5. Use the Boot Camp installer in
Windows After Windows installation completes, your Mac
starts up in Windows and opens a ”Welcome to the Boot Camp
installer” window. Follow the onscreen instructions to
install Boot Camp and Windows support software (drivers).
You will be asked to restart when done.
If the Boot Camp installer never opens,
open the Boot Camp installer manually and use it to complete
Boot Camp installation. If you have an external display
connected to a Thunderbolt 3 port on your Mac, the display
will be blank (black, gray, or blue) for up to 2 minutes
during installation.
