Install from USB trying to install on itself.

Hi,

I am trying to install from USB, I have followed the instructions in the installation guide. When it get's to partitioning it fails with the following error:

Failed to create a file system.
The ext3 file system creation in partition #1 of SCS!1 (0.0.0) (sda) failed.

There is no option to choose where to install Untangle?

I have two hard drives in the machine. Do they need formatting before the installation begins.

I think it is trying to install untangle on the USB drive it is installing from.

Cheers
