Mac 10 Windows 10 Installation Instructions

To install Windows, use the Boot Camp Assistant program that came with your Mac.

1. Using Boot Camp Assistant to create a Windows partition

Open the Boot Camp Assistant program in the Utilities subfolder of the Programs folder. Then follow the on-screen instructions.

  • If a message appears asking you to use a USB flash drive, insert the USB flash drive into your Mac. Boot Camp Assistant uses it to create a bootable USB drive for installing Windows.
  • When Boot Camp Assistant asks you to specify the size of the Windows partition, follow the minimum size requirements in the previous section. Indicate the size of the partition in accordance with your needs, because in the future it can not be changed.

2. Formatting the Windows partition (BOOTCAMP)

When Boot Camp Assistant shuts down, your Mac will restart in the Windows installation environment. If the installer asks where to install Windows, select the BOOTCAMP section and click “Format.” In most cases, the installer will automatically select and format the BOOTCAMP section.

3. Install Windows

Disconnect all external devices that are not required during installation. Then click “Next” and follow the on-screen instructions to start the installation of Windows.

4. Using the Boot Camp Installer on Windows

When the installation of Windows is complete, the Mac starts up on Windows and displays the “Welcome to the Boot Camp installer” window. Follow the on-screen instructions to install Boot Camp and the Windows support software (drivers). Upon completion, you will be prompted to restart.

  • If the Boot Camp installer does not open, manually open the Boot Camp installer and use it to complete the Boot Camp installation.
  • If you have an external display connected to the Thunderbolt 3 port on your Mac, this display will be blank (black, gray, or blue) during installation (up to 2 minutes).

Procedure for switching between Windows and macOS

Restart your computer, at startup, press and hold the Option (or Alt) ⌥ key to switch between Windows and macOS operating systems.
