.... Which doesn't work and it gives the error in the original post (Operating System Loader failed signature verification. WARNING: The file may have been tampered with) indicating that there are integrity checks that the current (and the 4.0.1-rc1) image are failing for the current generation of UEFI-enabled BIOS-es. What is not clear in the above? UEFI doesn't work and Legacy isn't supported. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.
