Install 64-bit Windows on your macOS computer using Boot Camp Assistant
If you wish to run both macOS and Windows on a single Mac computer, UITS recommends using Apple's Boot Camp utility to install a 64-bit version of Windows on your Mac. In macOS, the Boot Camp Assistant app will help you partition your Mac hard drive to accommodate both operating systems, so you can install Windows from an installation disk or an ISO image stored on a USB flash drive.
Partitioning your system's hard drive with Boot Camp Assistant may erase all your data. Before proceeding, back up/copy all personal files (documents, pictures, music, videos) to a flash drive, external hard drive, or cloud storage. Alternatively, you can use Time Machine with an external hard drive to back up your entire Mac computer; for instructions, see Mac Basics: Time Machine backs up your Mac
. If you need assistance setting up Time Machine, contact your campus Support Center
- Make sure your computer meets these requirements:
- At least 80 GB of free hard drive space
- You have either the keyboard and mouse (or trackpad) that came with your Mac, or a USB keyboard and mouse
- Obtain a USB flash drive (at least 16 GB).
- During installation, you will be prompted to enter an account name and password; this is for the administrator account, and should not be the one you generally use. You also will be prompted to enter your time zone.
- Ensure that the computer is plugged into a power source, as the entire process may take several hours.
- These instructions are intended strictly as a guide for installing a fully updated 64-bit version of Windows on a macOS High Sierra 10.13.x or newer computer at IU; if your computer cannot run that version of macOS, you'll need to follow Apple's Boot Camp Help: Install Windows on your Mac.
- Perform these steps in order.
Step 1: Check for macOS updates
Before configuring Boot Camp, it is critical to make sure that your Mac's software is up-to-date, which lessens the risk of encountering problems during installation:
- In the menu bar, from the
menu, click .
- At the top of the window, click
- If there are updates for your computer, in the upper right corner of the window, click
If you're prompted, enter an administrator's username and password, and if prompted, allow your computer to restart.
When your computer restarts, check for additional updates by repeating the steps above. Repeat the process until there are no new updates in the App Store.
Step 2: Confirm your macOS version
In the menu bar, from the Boot Camp Help: Install Windows on your Mac.
menu, click . The window will display the version of macOS on your computer. If you aren't running macOS High Sierra (10.13.x), you need to follow Apple's
Step 3: Turn off FileVault
To proceed, you need to divide your Mac's hard drive into a section for macOS and a section for Windows. This process is called partitioning a disk, and requires that you disable FileVault (whole-disk encryption provided by Apple):
- In the menu bar, from the
menu, click .
. The FileVault control panel will open, locked by default.
- Before you can disable FileVault, it requires you to unlock the control panel to show that you're an administrator on your computer. To do so, click the lock icon. Enter your administrator username (if required) and your password.
- You'll then be able to click
. To confirm, click .
Decrypting an encrypted drive can take some time, the exact time being determined by how much data is on your disk, the disk size, and your computer's hardware capabilities.
Step 4: Download Windows 10
The version of Windows 10 on IUware will not work with Boot Camp; you'll need to download Windows directly from Microsoft, and use a product key you get from IUware.
