Hi There,
I'm trying to install Ubuntu MATE 16.04 on a new machine and very stupidly erased windows whilst installing rather than installing alongide linux. The installation went well until I restarted, where it froze and the machine remained on. This is what comes up on the screen:
I have now tried several different distros and the same thing happens every time. When I go into BIOS, ubuntu comes up but when I try to get into it I am presented with the Perform Mok Management screen. At a loss as to what to do, please help!
Thanks in advance
