(Sorry for the inconvenience)

Once you have downloaded PC-BSD and verified its checksum, burn the file to the correct media type. This section demonstrates how to do so using several different applications and operating systems. Each application assumes that the correct media (CD, DVD, or USB flash drive) for the type of file is inserted.


Burning the CD/DVD ISO File on Windows

Several burning applications are available for Windows. This section will demonstrate how to use Windows 7's Disc Image Burner, ImgBurn, and InfraRecorder.

Windows 7 Disc Image Burner

Windows 7 has built-in support for writing ISO images to disc. Right-click on the .iso file in Windows Explorer and select Open with -> Windows Disc Image Burner to open the screen shown in Figure 2.6a. Click "Burn" to write the disc. See the Microsoft article txt=Missing Link[1] for more detailed instructions.

Figure 2.6a: Windows Disc Image Burner



txt=Missing Link[2] is an easy to use ISO burner for Windows that is available for free download. After installing and launching ImgBurn, select "Write image file to disk" from the main menu, seen in Figure 2.6b:

Figure 2.6b: Initial ImgBurn Screen


You can then use File -> Browse for a source file... to select the .iso file to burn; once selected, your screen should look similar to Figure 2.6c. Click the Write icon in the lower left corner to begin the burn.

ImgBurn will provide a status bar to indicate the progress of the burn. When it is finished, ImgBurn will eject the burner tray then reclose it in order to verify the burn. If the tray does not return itself, which may occur on a laptop, push the tray back in if you wish to verify the burn.


txt=Missing Link[3] is an open source burning application for both CDs and DVDs. Once installed, open InfraRecorder and click on the "Write Image" button shown in Figure 2.6d:

You can accept the defaults and click OK to start the burn. When finished, the burner tray will open and a dialog box will appear indicating that the burning process has finished.

Burning the CD/DVD ISO File on a BSD or Linux System

This section demonstrates how to burn the installation ISO on a Linux or BSD system using the following tools: K3B, Brasero, and growisofs.


The KDE desktop environment provides the txt=Missing Link[4] burning application. K3B has a similar interface to burning software found on Windows and is equally easy to use.

NOTE: depending upon your Linux distribution, K3B may or may not be included with the installation of KDE. If it does not appear in the KDE application launcher, you should be able to install it using your operating system's software management system. On a FreeBSD system, you can install the K3B package. If you are running an older version of KDE, use the pkg_add -r k3b command. If you are running KDE4, use the pkg_add -r k3b-kde4 command instead. On a PC-BSD system, you can install the K3B PBI using Using AppCafe®.

To burn your ISO, launch K3B and click "Tools -> Burn Image...". Figure 2.6f demonstrates this screen on a KDE4 system. On a KDE3 system, the menu item may appear as "Burn DVD ISO Image...".

Figure 2.6f: Selecting the Burn Image Tool Within K3B


A new window, seen in Figure 2.6g, will launch. Click the blue folder to browse to the location of your .iso file.

Figure 2.6g: K3B's Burn Image Screen


Once your file is listed, click the "Start" button. K3B will automatically eject the media once the burn is complete.


txt=Missing Link[5] is an easy to use burning application included with the GNOME desktop. A PBI is also available within AppCafe®. To launch Brasero within GNOME, click Applications -> Multimedia -> Brasero Disk Burner and the dialog window shown in Figure 2.6h will be displayed.

Figure 2.6h: Brasero's Initial Screen


If you click on Burn image -> Click here to select a disk image, you will be able to select your .iso file. Once selected, click "Open" to return to the screen seen in Figure 2.6i:

Figure 2.6i: Viewing the Image to Burn and the DVD Hardware Properties Within Brasero


The name and size of your .iso file should appear and Brasero will indicate the size of the media. The lower portion of Figure 2.6i shows the menu that appears if you click on the Properties button. You can change these options if you wish, but it is fine to keep the default settings. When you are ready, click the "Burn" button and Brasero will burn your ISO.


If you are familiar with using the command line on a FreeBSD or PC-BSD system, you can use the growisofs command line utility to burn the DVD. This utility is included with the dvd+rw-tools FreeBSD port which is installed by default on a PC-BSD system. If that software is not yet installed on a FreeBSD system, issue this command as the superuser:

pkg_add -r dvd+rw-tools

Depending upon the type of DVD burner hardware, you may have to configure the system to use it. If the device is ATAPI (i.e. not USB or SCSI), the ATAPI driver must be loaded. The superuser can issue this command:

kldload atapicam

If you just get your prompt back, the driver successfully loaded. If you get the message "kldload: can't load atapicam: File exists", this means that the driver was already loaded. If the device is USB or SCSI, no additional drivers need to be loaded if you are running the generic FreeBSD kernel. After inserting the DVD media into the device, you can start the burn using this command:

 growisofs -Z /dev/cd0=PCBSD9.0-RELEASE-x86-DVD.iso

If your device is not the first CD device, change the number 0 accordingly. If your ISO has a different name, substitute the correct name in the command shown above.

Burning the CD/DVD ISO File on a Mac OSX System

To burn the ISO on a Mac OSX system, go to Finder -> Applications -> Utilities -> Disk Utility. With a blank media inserted into the burner, highlight the device representing the CD/DVD writer and click the Burn button. This will open up a browser where you can select the ISO to burn. In the example shown in Figure 2.6j, the DVD ISO has been selected and the device is a Sony DVD writer.

Figure 2.6j: Using Disk Utility on Mac OSX


Once the ISO is highlighted, click the Burn button. A pop-up message will indicate that the device is ready to burn. Click burn once more and Disk Utility will write the ISO to the CD/DVD media.

Writing an IMG File to USB

To write an .img.bz2 file you will need the following:

  • a utility that can extract .bz2 zipped files
  • a utility that can write the image to a USB media; the utility that you use will depend upon your operating system
  • a USB thumb drive or hard drive large enough to hold the image

Once the image is written, boot from the removable device and proceed with the PC-BSD installation.

Writing the IMG File on a Linux or BSD System

If you selected to download an .img.bz2 file instead of an ISO, you can write the image file to a flash card or removable USB drive using the bunzip2 and dd command line utilities on a BSD or Linux system. On a FreeBSD system, the superuser can use these commands to extract the specified image and write it to the first plugged in USB device:

bunzip2 PCBSD9.0-RELEASE-x86-USBFULL.img.bz2
dd if=PCBSD9.0-RELEASE-x86-USBFULL.img of=/dev/da0 bs=64k conv=sync
63200+0 records in
63200+0 records out
4141875200 bytes transferred in 1395.261087 secs (2968531 bytes/sec)

When using the dd command:

  • if= refers to the input file to be written; it should end with an .img extension
  • of= refers to the output file (the device name of the flash card or removable USB drive); increment the number in the name if it is not the first USB device
  • bs= refers to the block size
  • conv=sync pads the final block so it is the specified block size

NOTE for Linux users: if you type mount with the USB stick inserted, you will see two or more device nodes corresponding to the USB stick. For example, /dev/sdc and /dev/sdc1, where /dev/sdc1 corresponds to the primary partition of the USB stick. Before using the dd command, ensure that the usb stick is first unmounted. When using the dd command, remember to use /dev/sdc (device node without the number) as the option for the output file of=. Once the dd completes, you might not be able to mount the USB stick on Linux as Linux has very limited support for UFS, the BSD file system that gets created on the USB stick.

Writing the IMG File on a Windows System

To burn the image file on a Windows system, you can use win32-image-writer. You'll also need a utility that can extract .bz2 files such as txt=Missing Link[6].

When downloading win32-image-writer, download the latest version that ends in -binary.zip and use a utility such as WinZip or 7zip to unzip the executable.

To extract the PC-BSD image file using 7-Zip, browse to the location containing your downloaded .img.bz2 file, as seen in Figure 2.6k.

Figure 2.6k: Using 7-Zip to Extract Image File


Click the Extract button and browse to the location where you would like to save the extracted image. Once extracted, your image will end in .img and is now ready to be written to a USB device using the win32-image-writer application.

If you launch win32-image-writer.exe, it will start the Win32 Disk Imager utility, shown in Figure 2.6l. Use the browse button to browse to the location of the .img file. Insert a USB thumb drive and select its drive letter (in this example, drive F). Click the Write button and the image will be written to the USB thumb drive.

Figure 2.6l: Using Win32 Disk Imager to Write the Image


Writing the IMG File on a Mac OSX System

To extract the .img.bz2 file on a Mac system, use Finder to browse to the location of the file, as seen in Figure 2.6m.

Figure 2.6m: Extracting the Image on Mac


Simply double-click the file to extract it to the .img format. Finder will create a second file with the .img extension.

To burn that .img file, insert a USB stick and open Terminal. Run the diskutil list command to find out the device name of the USB disk, unmount the USB disk, then use dd to write the image to the "raw" disk (rdisk). In the following example, an 8GB USB stick has a device name of /dev/disk1 and a raw device name of /dev/rdisk1.
