1. Download the ISO image of the installation CD.


2. Use Disk Utility to burn the image into a CD.


3. Use Disk Utility to partition the hard drive.


4. [Plug in USB mouse/keyboard.]


5. Boot the "live" version of Ubuntu from CD.


6. [Connect to wireless router.]


7. Click the "install" icon on the desktop.

If you use a wireless router, make sure, before starting, that you know its name, security method, and password (key). To get the first two, click on the wi-fi icon, select "Open Network Preferences…," and click "Advanced…"

In step 3, select the hard drive in the pane on the left, click the "Partition" button, and then drag upward the bottom border of the picture of the disk partition. This will create an empty block at the bottom. If I recall correctly, the minimum size for an Ubuntu installation is 20 gigabytes. (Don't be a disk miser. I had 440GB of disk space available, and didn't think twice about allocating twice the minimum size.) Be sure to click "Apply" before exiting Disk Utility.

Step 4 is necessary if your keyboard and mouse/trackpad are wireless. Here is information on use of the Magic Trackpad with Ubuntu.

In step 5, hold down the c key while rebooting.

Step 6 is necessary if you use a wireless router for Internet access. Ubuntu will prompt you to provide what it needs to connect to the router.

After installation, hold down the option key while booting to run Ubuntu. The bootstrap procedure will indicate that you have a choice between OS X and Windows. Click on "Windows" to select Ubuntu.
