Unable to install from usb disk to usb disk.
When trying to install FreeNAS 11.2 Beta1 from USB installation media to USB disk the follow error is encountered.
"Can't work out which disk we are booting from"
See attached screen shot for entire error message.
As a workaround if you wait until the boot device is selected than insert the target usb installation media after it will continue booting in to the installer.
