Pre-installation Tasks

Back Up Your Data[edit]

Be sure to back up all important data on the computer before installing GhostBSD. The GhostBSD installer will not provide a prompt before making changes to the hard disk drive. Once the process has started, changes to the hard disk drive cannot be undone.

Check for FreeBSD Errata[edit]

GhostBSD is based on Trueos, and TrueOS is based on FreeBSD. Although the TrueOS Project strives to ensure that each release of TrueOS is as stable as possible, bugs occasionally creep into the process. On very rare occasions those bugs affect the installation process. As these problems are discovered and fixed, they are noted in 12.0-RELEASE Errata page on the FreeBSD web site. Check the errata before installing to make sure that there are no problems that might affect the installation.

Prepare the Installation Media[edit]

The GhostBSD installation media is available as a .iso file. Copies of GhostBSD installation media are available for free at the GhostBSD download page.

Creating a bootable USB Flash Drive[edit]


After downloading the appropriate .iso file, copy it to a USB flash drive using one of the methods described below. Depending on the operating system, issue one of the following appropriate commands:

On BSD[edit]

dd if=/path/to/GhostBSD19.04.iso of=/dev/da0 bs=4m conv=sync

On Linux[edit]

sudo dd if=GhostBSD19.04.iso of=/dev/sdf bs=4M conv=sync

On Mac[edit]

dd if=/path/to/GhostBSD19.04.iso of=/dev/disk2 bs=10240 conv=sync

On Windows[edit]

  1. Download the desired .iso file
  2. Download Disk Imager from
  3. Insert your USB flash drive
  4. Note the drive letter assigned to your flash media
  5. Start Disk Imager
  6. Select the downloaded file and target device, and click "Write"
  7. Remove your USB flash drive when the operation is complete

Other USB Flash writer tools for Windows[edit]

Balena Etcher [1] Works for Windows, MacOS, & Linux Rufus [2] Works just for Windows, needs a checkbox selected to do a pure write of .ISO image file

ISO CD / DVD writer tool[edit]

ISORecorder [3] works from Windows Menu to write a .ISO file into a CD or DVD


The steps described above will create a bootable GhostBSD system on a USB flash drive. To start a live session, connect the USB thumb drive into the computer and reboot the computer. Further information can be found here.
