What I've noticed is that the BT4-pre-final iso needs to be burned into a *physical* media...this DVD is then used to boot a computer other than our netbook, and *then* installation through conventional means can be successfully completed: the 4GB USB can be formatted/installed with the BT4 distro.
Backtrack 4 USB Install - Offensive Security
UGH.
The distro team decided to change the booting method from the BT4 *Beta* ISO, a package needing only to setup VMWare Windoze and running the scripts to install onto the USB.
^^^Running these scripts in OSX is something I'm not used to. I know Darwin can compile nearly anything(ruby,pearl,python,c) with the proper Dev tools, however this is subject matter I just have not much understanding over.
To run things entirely on the softside...ie., not needing to burn a DVD, you can at least go live with the BT4 Beta...
BT4Beta image lacks certian apps that I just can't live without, however one could perhaps just upgrade their system from the
BT repository.
