lalajee Posted August 9, 2018 Report post Posted August 9, 2018 If I have scureboot turn on then I cant boot up the system into PXE with USB comes up with error "An Operating System wasn't found" but if I change the scureboot to off then it works fine. I got lot of laptops to build as windows 7 and this is slow the process, Can you please let me know what I have done wrong Quote Share this post Link to post Share on other sites More sharing options...
