Hi Sidewinder,
I currently have exactly the same situation as you. A client has puchased 10 Dell Vostro 320 all in one machines which I have created an image for and uploaded to WDS.
In your previous post you mentioned you had a boot error after loading the image, would it happen to be 0xc000000f?
I have that exact error and although you seem to have resolved your issue it is not clear how you were able to get past the boot error?
Any feedback would be appreciated.
