You can either order a CD-ROM from PC-BSD Software, or download PC-BSD's CD-ROM image file from PC-BSD's web site. If this is what you did, this section will assist you to burn PC-BSD onto a CD-R (Writable) or on a CD-RW (Rewritable). This tutorial assumes you already have:
At this point, you will have to choose how you want to burn your .iso file. If you use a Windows computer, you can choose from Nero, Burnatonce, or CDBurnerXP. If you use a Unix computer with KDE (such as PC-BSD), you can use K3B. Alternatively, if you use a Unix machine with Gnome, you can use Gnome Baker to burn your CD-ROM.
Ahead Nero Burning ROM is one of the most popular commercial applications on Windows to burn CD-ROMs and DVD-RAMs. Although it is commercial, you usually have a month free to test it. Let's see how you can burn your CD-ROM in a few steps. Launch Nero, and click "Recorder > Burn Image", select your .iso file and burn your CD-ROM. Alternatively, you can click "File > Open":
In the Windows dialog box, select the penultimate option labeled "Image Files" to display .iso files in your file browser:

Browse to the directory where you stored your .iso file of PC-BSD; you should see your file listed. Select it and click "OK". On the next screen, click "Burn", and Nero will start burning your disk:

After a few minutes, Nero will alert you that the burning process is complete and will eject the CD-ROM for you.
Burnatonce is a freeware application that you can use freely for your personal needs. It is a simple and light-weight application. To use Burnatonce, simply launch it, and click "File > Load New Image...":
Your PCBSD .iso file will then be listed in grey in Burnatonce. Click "Write", and Burnatonce will start burning your CD-ROM:

A few minutes later, Burnatonce will let you know that the CD-ROM was burned successfully.
CDBurnerXP is another freeware application for Windows. It has a modern interface and looks similar to its commercial counterparts. Using CDBurnerXP is also very easy: Launch the application. A dialog window will appear and ask you whether you want to continue burning files on a writable disk that already has files (multi session), or whether your CD-ROM doesn't have any content yet (No multi session). You will click the second option "Don't Continue Disc (No Multi Session)":

Afterwards, CDBurnerXP's main interface will show up. In the upper-left corner, click "File > Write Disc from ISO File...":

A dialog window then appears for you to select your .iso file. Under "Select an ISO image to write", click the "..." button to select your file:
The file will be listed in the main window. The only thing you have to do is "Write Disc", and CDBurnerXP will start burning your .iso file onto your CD-ROM:

Any Unix-based operating system such as PC-BSD, FreeBSD or Linux distributions using KDE are suitted to K3B, one of the best CD-ROM burning application for Unix. K3B has a similar interface to other modern burning software that you find on Windows, such as Nero Burning ROM or Easy Media Creator. K3B is equally easy to use. Launch K3B and click "Tools > Burn CD Image...":

A new window will show up where you can choose your .iso file. Under "Image to burn", click the blue folder icon to select your file:

Once your file is listed, click the "Start" button in the top-right corner, and K3B will burn the .iso file onto your CD-ROM.
Gnome Baker is probably the best CD-ROM/DVD burner for the Gnome desktop. It is also easy to use. To burn your .iso file, first, launch Gnome Baker and click "Actions> Burn CD Image":
A dialog window will be displayed and you will be able to select your .iso file. Select it and click "OK":

The last window allows you to select your CD-ROM drive, as well as a few other options. Leave these options as default. Click "Start" and Gnome Baker will begin to burn PC-BSD onto your CD-ROM drive:

Gnome Baker will alert you when it is done burning your file after a few moments.
Now that you have a CD-ROM with the latest version of PC-BSD, let's go through installation!
