I have two identical Dell XPS 15z laptops. I am trying to do a System Image Recovery from one laptop to the other. The problem: when Windows 7 restarts to do the recovery, it does not see the system image on the external USB drive. I think it does not see the external drive, period. I tried backing up and restoring the same laptop (to eliminate the possibility that "cross-recovery" is not supported), and it's a no go either. I am following this procedure: How to Do a System Image Recovery in Windows 7. The part where it fails is #5 and #6 of "STEP TWO". EDIT: SOLUTION - The built-in Recovery tool in Windows does not support USB 3 by default. USB 3 drivers need to be loaded. See the discussion below for a link to additional information.
