You will need the following tools
- A zip extractor, such as WinRAR, WinZip or 7zip
- PhysDiskWrite (at this time, it is physdiskwrite 0.5.2.zip)
This allows you to write the disk image to the USB stick
- The FreeNas ISO image.
In my case, I downloaded FreeNAS-8.3.0-RC1-x64.img.xz This is the newest version at this time. You may find a newer version.
The important bit is to download a full install version and not an *update*.
For example, do not download FreeNAS-8.3.0-RC1-x64.GUI_Upgrade.xz
1) Create a temp directory, say C:\dooda
2) Extract the contents of physdiskwrite 0.5.2.zip into c:\dooda
3) using your favourite zip extractor, extract the contents of the FreeNas XZ image into c:\dooda
4) rename whatever came out of the XZ file into something simple, say FreeNAS.img.
5) Open a command prompt (as administrator) in c:\dooda
6) type physdiskwrite.exe -u FreeNAS.img and look very carefully at the displayed results. In my case, I see the following

Which disk do you want to write? (0..2) 2You need to decide which of the drives shown is the one to dump the FreeNas image on.
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 2 with new data. Proceed? (y/n) y
Whatever drive you select will be totally overwritten. Totally!
Select carefully!
I can see that drive 2 is the smallest drive (8GB), i.e. my USB stick, so I enter '2' and press ENTphydER.
Please note that there mustn't be any partitions at all on the USB stick.
If there are, you will get an error complaining that it failed to write after 0 bytes (or some such).
To completely empty the USB stick, do the following
1) Open a command prompt (but do so as an admin)
2) Enter diskpart
3) Enter List disk
(this will list your disks and allow you to find the drive number of your USB stick)
4) Enter Select disk N
(where N is the disk number of the USB stick. See screen dump and notes above)
5) Enter Clean
Done!
You can now install FreeNas on your hardware by booting on your newly-created USB stick.
In my case it is an HP Proliant N40L.
I have updated its BIOS as described in this article.
