I'm having a similar issue as well. When I begin the image pull task from the console, the client machine runs sysprep, then boots to dos mode. I pressed F8 like you suggested and went through the prompts, however when I got to the NGCTDOS file, I selected "Y" to make sure it would do the same thing as I have observed before (and the same as others have observed), and it rebooted.
Upon reboot, it showed the windows splash page, then gave me a couple of errors and said that I had to run setup again because windows was not set up properly.
Hence, I had to put in my windows disk and perform a repair. I'm in the process right now and hoping that I don't have to carwash the laptop again.
The laptop is an HP NX6325 with a Broadcom NetXtreme.
I am currently evaluating GSS 2.0 for purchase, and needless to say I am a bit disheartened that I cannot update the trial product, and that I am having issues with the most basic task right out of the box.
