Install Windows on your Mac. Boot Camp is a utility that comes with your Mac and lets you switch between macOS and Windows. Download your copy of Windows 10, then let Boot Camp Assistant walk you through the installation steps. Oct 23, 2019 I have a Mac Mini 2018 128gb SSD. I regret purchasing the smallest hard drive, especially since now I'd like to use bootcamp. I tried to bootcamp and it left me with about 10gb of space.

An external USB flash drive with a storage capacity of 16GB or more, unless you're using a Mac that doesn't need a flash drive to install Windows.
A 64-bit version of Windows 10 Home or Windows 10 Pro on a disk image (ISO) or other installation media. If installing Windows on your Mac for the first time, this must be a full version of Windows, not an upgrade.

How to install Windows 10 on Mac
To install Windows, use Boot Camp Assistant, which is included with your Mac.
1. Use Boot Camp Assistant to create a Windows partition
Open Boot Camp Assistant, which is in the Utilities folder of your Applications folder. Then 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.
2. 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.
3. Install Windows
Unplug any external devices that aren't necessary during installation. Then click Next and follow the onscreen instructions to begin installing Windows.
4. 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.
