#TechBytes: How to officially install Windows on Mac
What's the story
It's not common knowledge that Microsoft Windows can be installed on MacBooks, but Apple officially supports running both macOS and Windows on its devices.
macOS has a utility called Boot Camp that facilitates the installation of Microsoft Windows, and allows users to change between macOS and Windows as per their needs.
Here's a comprehensive guide to installing Windows on your Mac.
Basic requirements
Basic criteria to meet before installing Windows on your Mac
Before you can go about installing Windows, there are certain criteria to be fulfilled.
You need an Intel-based Mac, and a Microsoft Windows installation media or disk image (ISO) containing a 64bit version of Windows 8 or above.
Additionally, you need 55GB free space on your Mac's startup drive, and a 16GB USB 2 flash drive (in some cases).
Caveats
Caveats to keep in mind before beginning installation
Once you're sure you meet these requirements, check if the Windows you're installing is supported by your Mac's hardware (this isn't really required, but prudence never hurt).
If you already have official Windows as an ISO file, well and good.
If you have Windows on DVD or a USB flash drive, you might need to create a disk image or download the ISO.
Boot Camp
Using Boot Camp and starting the Windows installation
Once every thing is in order, open Boot Camp Assistant from by going to 'Applications', then 'Utilities' on your Mac.
Upon opening Boot Camp Assistant, follow on screen instructions to repartition your Mac's startup disk, and download support drivers required for Windows.
In case you're prompted during the installation, connect a blank USB 2 flash drive.
Installing Windows
Final steps to complete your Windows installation
Once Boot Camp Assistant completes its part, your Mac will restart and present you with the Windows installer.
If you're asked to specify the install directory for Windows, select the BOOTCAMP partition, then click format. If you're not asked, then this has been set automatically.
Then, unplug any unnecessary external devices, and follow the on-screen prompts to install Windows, and Windows Support Software.
Switching
How to switch between macOS and Windows
Once you're done installing Windows and Windows Support Software, you can seamlessly switch between them.
To switch from Windows to macOS, use the Boot Camp icon on your system tray and restart your device.
To switch from macOS to Windows, go to System Preferences > Startup Disk, and select the Boot Camp volume.
Holding down the Option key while restarting your Mac also works.
