Yeah, I know about that kinda hidden partitions
I was referring to what elroy pointed.
That's excatly how the ad described it, hold a backup copy of windows. What I understood, they use ghost to dump the new computers with image, and, if the user messes it up, the hidden partition should hold the image file for easy recovery.
But then again, the ad also said there are only few platforms, which would mean only two images, which would mean it would be a waste of space to have every computer hold the image when you can easily fit it on a few cds...
Thanks for the second link
