Recently one of the laptop models has started to show a scrambled screen after choosing Zenworks Imaging Maintenance. I cannot see the things I type but it is working if I type img and then know all of the keystrokes to launch and image. This is only happening on one model of computers. If I set the laptop to Legacy boot mode I can see the screen correctly however I am getting a GPT error when trying to upload or download an image so it must be in UEFI mode for me to do the imaging. Any help would be great considering I have to image another 170 computers of this model that we just got in. Also this was working correctly until 10/15/2015 and no changes have been made on the server.
