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.
