Hey all, [Machine: Surface Pro 2 256g] Was just wondering if anyone else has encountered this issue and would have a possible fix. I (unfortunately) installed all Windows Updates and Firmware Updates and now have this strange issue. I can successfully boot into my machine (maybe after 3 retries from the UEFI Boot Loop) and everything looks fine once I log in (no real indication in the event logs there are any issues). However, my boot screen appears red (from the boot loop) but when I try to 'Install the default keys', I get prompted with the following message: 'Secure variable update is locked down!' Is there a fix for this? cmd? powershell? I tried a factory reset with no luck. Allows me to complete it but then I get the random boot loop again. Chieftan.
