In order to use Ubuntu with AMD64 processors in 64-bit mode, you must get a different disk on your own. There are several ways of doing this: downloading an ISO (disk image) and then burning it to CD yourself, ordering the CD from Ubuntu (for free), or ordering it from an online Linux CD provider (for a nominal cost).

Downloading and Burning Ubuntu Desktop CD ISOs to CD
To download an ISO of the Ubuntu Desktop CD, go to the Ubuntu website at, find the link to the download page, and then select and download the appropriate version for your machine. Remember that the ISO file you will be downloading is a heavyweight, weighing in at just over 700MB, so the download will take a bit of time. Don’t count on getting it all downloaded and done before dinner . . . or, if you happen to be using a dial-up Internet connection, before dinner tomorrow. Yikes!

Burning the ISO to CD in Windows
Once the Desktop CD ISO has been downloaded, you need to burn it to CD before you can use it. Although Windows has built-in CD-writing capabilities, it does not have the ability to burn ISOs. To burn an ISO to CD in Windows, therefore, you must use a third-party commercial application, such as Nero. If you don’t have a commercial disk-burning utility installed on your system, try the free and handy ISO Recorder. To get ISO Recorder, visit to Once the download is complete, double-click the ISORecorderSetup.msi file on your hard disk to install it. After the installation is complete, burn your ISO to CD by double-clicking the Ubuntu ISO file on your disk and selecting Copy image to CD in the popup menu. A CD Recording Wizard window.

It is generally best if you burn installation or live CDs at a lower speed than the maximum speed allowed by your drive, in order to reduce the chance of error (with 2X to 4X speeds considered optimal). To do so, click the Recorder Properties button in the CD Recording Wizard window, and then drag the slider in the Properties window down to about 4X. Next, pop a blank CD into the drive and click the Next button. The CD burning process should begin. Once it’s done, the CD should pop out of the drive, and if all goes well you’ll have yourself an AMD64-compatible live CD.

Burning the ISO to CD in OS X
Although Ubuntu no longer comes in PowerPC editions, the i386 editions can be installed and run on Intel-based Macs. You can also, of course, download ISOs for other architectures on your Mac, and then burn them to CD for use on other machines. To burn an ISO file to CD in OS X, first check to make sure the ISO image is not mounted by opening a Finder window and checking the disk area at the top of the left pane. If it is mounted, a white drive icon will appear in that location. If the drive icon is there, click the arrow next to that entry to eject, or unmount, it.

After that, click Applications in the same Finder window, and then look for and open the Utilities folder. In that folder, find and then double-click Disk Utility. If the ISO is not listed in the left pane of the Disk Utility window when it opens, go back to the Finder window, locate the Ubuntu Live CD ISO you just downloaded, and then drag it to the left pane of the Disk Utility window, just below the listings for your current drives. Once the ISO file appears in that list, click it once to highlight it.

To complete the process, click the Burn icon in the Disk Utility window’s toolbar, and then insert a blank CD in your drive when prompted to do so. Once the blank disk is inserted and recognized, you will be able to adjust the burn speed from the drop-down menu next to the word Speed. Select as low a speed as your hardware will allow, which, depending on the age of your Mac, will probably be 4X to 8X. Finally, click the Burn button in that same window, and the burning process will begin.

Ordering an Install Disk from Ubuntu
The easiest and most foolproof way to get an Ubuntu Desktop CD is to simply order one (or more) for free from Ubuntu; you don’t even have to pay shipping or handling. Ubuntu will not only send you one install CD for your particular machine architecture, but they will actually send you one for each of the architectures they support: i386 and AMD64. In fact, you don’t even get to choose which you want; it’s basically an all-or-nothing deal, which in this case isn’t such a bad thing. Of course, the only downside to this approach is time. It can take four to six weeks for you to get the CDs in this manner, so if you’re impatient, you might want to opt for one of the other methods. To order your install CDs from Ubuntu, go to and follow the directions there. It’s easy.

Ordering an Install Disk from Other Online Sources
If you are in a hurry to get your install CD, you can also order a copy from one of the many online sources that specialize in copying and selling install CDs for a variety of Linux distributions at very low prices. For example, you can get an Ubuntu install CD from LinuxCD ( for a quarter shy of two dollars. CheapBytes ( and UseLinux ( are two other well-known sources you might want to try.
