Installing FreeNAS 8 to USB on Windows

This ‘how to’ guide will step you through the process of installing FreeNAS 8 to a USB memory stick using a Windows computer.

This can be a handy too if you have a system that has crashed, and you just want to get it back up and running so you can copy files off of it. You can simply plug in a USB memory stick with FreeNAS installed to it, configure it to share out one or more of the drives, and access the data from the network.

You will need a USB memory stick that is 2GB in size or larger. This example is using the 64bit version of FreeNAS, however the same will apply to the 32bit version, as long as you update the file names in the examples to suit the 32bit file names.

Prerequisites:

- 2GB USB Memory stick (minimum).
- 7-Zip or another application that is capable of extracting .iso and .gz files. (Download from www.7-zip.org).
- physdiskwrite (Download from http://m0n0.ch/wall/physdiskwrite.php ).

Download FreeNAS 8

Download the FreeNAS 8 ISO:

FreeNAS 8.3.0 64bit

(Check www.freenas.org to obtain the latest version of FreeNAS)

Extract the FreeNAS 8 ISO

Open the FreeNAS 8 ISO file in 7-zip.

FreeNAS 8 in 7-zip

Double click the FreeNAS-x64.img.xz file:

FreeNAS-x64.img.xz

It should load this compressed image in 7-Zip:

FreeNAS-x64.img 7-Zip

Click the “Extract” button at the top.

FreeNAS 7Zip Extract Button

The extract windows should now appear.

Extract FreeNas To Folder

Simply click “ok” on this window to extract the file to the folder your FreeNAS ISO was in. Change the output path if you want to store it somewhere else.

Extracting FreeNAS 8 img file

Close 7-Zip once the extract has completed.

Write the FreeNAS 8 Image to a USB memory stick:

Make sure you have downloaded physdiskwrite (link is in the prerequisites section at the top). Make sure this is extracted into the same folder as where you extracted the FreeNAS-x64.img file in the previous step. In our case, this will be “C:\freenas”.

Open a command prompt window.

If using Windows Vista, Windows 7, Windows 2008, Windows 8, or newer, open a command prompt window “as administrator”. Meaning, right click a shortcut for the command prompt, and select “Run as administrator”.

change the directory to where physdiskimage and the freenas image was extracted to. In my case “C:\Freenas”

cd c:\freenas

Run physdiskwrite to write the FreeNAS image file to your USB memory stick:

physdiskwrite.exe -u FreeNAS-x64.img

This will prompt you asking which device the FreeNAS image should be written to.

Example output:

c:\freenas>physdiskwrite.exe -u FreeNAS-x64.img

Which disk do you want to write? (0..5)

In this case, my USB memory stick is PhysicalDrive5, so I entered “5″ and hit enter.

You will be prompted for a confirmation. Enter “y” and press enter to confirm.

WARNING: that disk is larger than 2 GB! Make sure you're not accidentally
overwriting your primary hard disk! Proceeding on your own risk...
About to overwrite the contents of disk 5 with new data. Proceed? (y/n) y

It will now write the FreeNAS image file to the USB memory stick.

32636928/2000000000 bytes written

This will take a few minutes.

2000000000/2000000000 bytes written in total

c:\freenas>

Once its completed, FreeNAS will be installed on the USB memory stick.

Unplug the USB memory stick, and test it in another computer by booting off it. If all went well, it should boot into FreeNAS, and you can start configuring it.

You may need to change the boot order, or press the ‘boot menu’ button when the PC is booting to be able to boot off the USB device.
