How to install Windows 7 on a Mac Pro

1. Update Bootcamp to at least version 3.1. Previous versions do not support Windows 7. You can download the required update from Apple's support website.
2. Open Bootcamp through 'Finder.' Go to 'Applications,' 'Utilities' and click on the program to open it.
3. Create a partition for Windows. You can use the default settings or adjust the size to your liking. You must have enough free space on your current hard drive to create a new partition.
4. Insert the Windows 7 installation disc when the partitioning is complete and click 'Start Installation' to proceed. Your machine restarts.
5. Select the new partition you created when the Windows 7 installation process is done loading. Choose the format option near the lower right-hand corner of the screen. The partition must be formatted before Windows can be installed. Be careful not to format any other partition or data will be lost. Click 'OK' to confirm the formatting and the Windows 7 installation process will begin.
6. Follow the instructions on the screen to continue the process. Your computer reboots after some time. Upon reboot, Windows 7 will load and you will be asked to set several settings such as language and keyboard layout. After the settings are chosen, installation is complete and the Windows desktop will appear. Your Mac will now load Windows 7 by default after every restart.
