Is It Easy to Dual Boot on a MacBook?

Dual booting is a term that refers to being able to choose from multiple operating systems on your computer when you start up each time, effectively giving you control of different disk partitions on the same machine. Dual booting has become easier to accomplish as technology progresses, especially on the Mac with the Boot Camp utility, which manages operating system set up, partitioning and startup for you.

Necessities

In order to dual boot, you'll need enough space on your computer. A good estimate for any installation is about 10GB of free space; this gives you enough room to install the actual operating system as well as more room to store your files. You can opt to give more space to your second boot partition, of course, but be sure you wouldn't be losing too much space. You will also need a legitimate installation disc for the operating system you are going to install on your second boot partition.

Preparation

Before starting the actual installation, it's important to back up all your files. This should be done every so often regardless, but before you take on a task that directly affects your hard drive, you should make sure everything is backed up and saved. If you have an external hard drive, that's a great place to put all of your important files.

Installation

Creating your second partition and installing the operating system is all done through Mac's Boot Camp utility. Open your "Applications" folder, open the "Utilities" subfolder and double click "Boot Camp Assistant" to begin. The first part of the setup process will be to partition your hard drive, setting up the second one for your upcoming installation. After this is complete, you will be asked to insert your Windows, or other operating system, installation disc to begin the installation process. When the operating system is installed, your computer will be ready to dual boot.

Choosing the Operating System

To use the dual boot feature, restart your computer. As your computer turns on, press and hold the "Option" key until you see two hard drive icons appear on your screen. These are the icons for your two partitions, and they will be labeled by the operating system installed on each one. Simply click one to start up with that operating system.
