I have 20 laptops that I need to setup and would love to be able to do a simple image using clonezilla. However, no matter what I have tried so far (disabling Secure Boot, Enabling Legacy Boot) the machine refuses to boot to the USB that I have plugged into it. So my questions is, does HP ProBooks have some kind of vendetta against Linux, or is there some step I am missing to get this to work? I know the USB drive works as I have used it on another Lenovo Thinkpad just recently (which I am starting to think would have been a better purchase than these ProBooks). Any help is greatly appreciated.
