How to Dual Boot Mac & Windows

By J.S. Copper

With the introduction of Intel-based computers, Apple included the ability to install Windows alongside the Mac OS X system. Dual-booting both operating systems is only available to Intel-based Macintosh computers, as the OS X system does not run on generic PC hardware. Thanks to the inclusion of Boot Camp in the latest Mac OS, installing Windows is quite simple.

Things You'll Need

  • Intel-based Macintosh computer
  • Windows installation disc
  • Boot Camp

Step 1

Open Boot Camp Assistant ("Applications" > "Utilities"). Set the size you would like allotted to the Windows drive, you will need at least 10GB. Select "Partition" to create the Windows partition.

Step 2

Select "Start the Windows Installer" once the partitioning completes. Click "Continue."

Step 3

Select the newly created Windows partition and click "Continue."

Step 4

Insert the Windows installation disc into the Macintosh computer and click "Start Installation." The system will boot into the Windows installation disc.

Step 5

Follow the on-screen instructions to move forward with the installation. Select "Disk 0 Partition 3 BOOTCAMP" when asked which drive to install on. Select "Drive Options (advanced)" and click "Format." The drive must be formatted for Windows with the NTFS file system. Select "OK," "Next" to proceed with the installation. Once complete, the computer will restart and load Windows.

Step 6

Insert your Mac OS X Install DVD. Open the disc via Windows Explorer and double-click "Setup.exe." This will install the necessary drivers to allow Windows to interact properly with the Apple hardware.

Tips & Warnings

  • Hold down the Option key while booting up the computer to select which operating system you'd like to use.
