Got a laptop with SecureBoot that only boots: 1. preinstalled Windows 8.1 2. Acronis live CD Can something like mokutil be used IN WINDOWS to edit the MOK, in order to boot a ubuntu live CD or even install it? Could disable SecureBoot if I must, but only temporarily. Is there a way to find out what distro of linux the manufacturer already has included the key for in the MOK? Ideally from windows, ie with SecureBoot enabled?
