I have the same issue and have no clue on how I am going to image these. I have 875 of them, this is really bad. I would advice anyone no to buy these units, DELL is lying by saying that they are Enterprise grade. I tried to create a USB stick for Clonezilla - it works for other systems, it just freeze on that tablet. I tried creating a PE4 USB drive, it boots but no NIC, beside importing the driver.
