This section describes items specific to the UFS choices for partitioning.

Select Auto (UFS) BIOS or Auto (UFS) UEFI from the list (Partitioning) depending on the needs of the target system.

Single Disk

If there is only a single disk, the installation will perform the remaining steps automatically, there is nothing more to do, so proceed to Continue with the Install.

Multiple Disks

If the system has multiple eligible target disks, the installer will prompt to choose the target and other options.

Select Disk

Select the target disk where the installer will write out the pfSense® software, e.g. ada0. The installer will show each supported hard drive attached to the firewall, along with any supported RAID or gmirror volumes.


Select Disk

Select Entire Disk when prompted. pfSense software does not support sharing a disk with another operating system.


Use the Entire Disk

Partition Scheme

Select the partition scheme to use for the disk:


The GUID partition table layout. Used by most current x86 hardware. May not function on older hardware/BIOS versions. Try this method first.


BSD Labels without an MBR, which used to be known as “dangerously dedicated mode”. This method should work on most hardware that cannot use GPT. This was the method used by older versions of pfSense software.


Select this only if GPT and BSD do not work on a specific piece of hardware.


The other choices are not relevant to hardware that is capable of running pfSense software.


Partition Scheme

Partition Editor

Select Finish to accept the automatic partition layout chosen by the installer, then select Commit to write the partition layout to the target disk.


The partition sizes and other values can be customized here, but this is rarely necessary or appropriate. For nearly all installations, the default sizes are correct and optimal.

Proceed to Continue with the Install.
