How to install Windows using Boot Camp
Boot Camp helps you install Microsoft Windows on your Mac. After installing, restart your Mac to switch between OS X 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*
An Apple keyboard, mouse or trackpad, or a USB keyboard and mouse
At least 55 GB of free disk space on your startup drive
For some Mac models, you also need a blank 16 GB or larger USB flash drive
*If you want to install older versions of Windows, check to see if your Mac supports this. If you're installing Windows for the first time, use a full installation (not an upgrade) disc or disk image.
Check System Requirements
Some versions of Windows require a certain processor, and more hard drive space and memory (RAM) than others. Check the documentation that came with your copy of Windows to find out what you need. Then use System Information to see what your Mac currently has.
Get a Windows disk image
When you purchase Windows, it comes as a disk image file (ISO) that you download, or as an installation disc or USB flash drive. If your copy of Windows came on a DVD, you should create a disk image of it to work with Boot Camp. If your version of Windows came on a USB flash drive, you can download an ISO from Microsoft.
Open Boot Camp Assistant
Boot Camp Assistant guides you through installing Windows on your Mac. Open this app from the Utilities folder in the Applications folder and follow the onscreen instructions to automatically repartition your startup disk and download related software drivers for Windows. If you're prompted during installation, connect a blank USB flash drive.
Format your Windows partition
When you complete the assistant, your Mac restarts to the Windows installer. When you're asked where you want to install Windows, select the BOOTCAMP partition, then click Format.
Install Windows
Follow the onscreen prompts to finish your Windows installation.
Restart your computer
After Windows is installed, you can switch between OS X and Windows. Use the Startup Disk preference pane in OS X, or the Boot Camp system tray item in Windows to select your startup disk, then restart your computer.
