Hmmm, interesting. I haven’t had any problems using a single resizable partition. I wonder if that’s because all of our machines still have the 100mb partition still in place when they are imaged, and perhaps the image just replaces the OS partition instead of the system reserved.
Our machines are all typically the Dell Latitude series (couple of Precisions, but they work too), and the master image came from a modified e6510 build (it’s been converted to a VM, since).
