Boot Camp Installation & Setup Guide
1 Open Boot Camp Assistant, located in the Other folder in Launchpad.
2 Select the option to install Windows, select other options you need, then click Continue.
Here are the other options you can choose:
If you want to install Windows from a USB flash drive and you have a Windows ISO image, select the option to copy the image to a USB flash drive. If this option isn’t available, your Mac doesn’t support installing Windows from a USB flash drive.
If you haven’t already downloaded the Windows support software for your Mac, select the option to download it. In a later step, you’ll install the Windows support software on your Windows partition.
3 Follow the onscreen instructions for the options you selected.
4 When you’re asked to create a Windows partition, specify a partition size.
If you need help determining the best size for your Windows partition, refer to your Windows installer documentation. For Windows 8, create a partition that is at least 30 GB.
In a later step, you’ll format the Windows partition.
5 Insert the installation disc for the 64-bit version of Windows into your Mac’s optical drive or external optical drive, or insert the USB flash drive with the 64-bit version of Windows into a USB port on your Mac.
6 Click Install.
Boot Camp Assistant creates the Windows partition, restarts your Mac, and opens the Windows installer.
