For test purposes we pxe booted an IBM Thinkpad X100e with ZFD 7 to see if imaging would work. (Purchasing decision). Machine booted fine, connected to network and uploaded image no problem. Downloaded to another to test receiving the image, it completes successfully but on boot gives message "There has been a signature failure." Any info on compatibility of Win 7 with ZEN 7 imaging, any workarounds etc? We are not in a position to move to ZEN 10 at this point, but need a way to leverage Windows 7.
