If you selected to download a "Boot only USB for network & internet installs" .img file, you can write the image file to a flash card or removable USB drive using the built-in dd command line utility on a BSD or Linux command system. On a FreeBSD system, the superuser can use this command to write the specified image in the current directory to the first plugged in USB device:

dd if=PCBSD8.1-x86-USB-bootonly.img of=/dev/da0 bs=5k

When using the dd command:

  • if= refers to the input file; in our case, the name of the file to be written
  • of= refers to the output file; in our case, the device name of the flash card or removable USB drive. You may have to increment the number in the name if it is not the first USB device. On Linux, use "/dev/sda" to refer to the first USB device.
  • bs= refers to the block size

To burn the .img file on a Windows system, you can use the physdiskwrite graphical utility.

NOTE: The USB images are FreeBSD-UFS formatted, and will not show up as a viewable file-system under Windows.
