Quite possibly SecureBoot (maybe with a dash of UEFI added)

Switch SecureBoot off.

The exact process for doing that will depend on your hardware, but normally there's a way to pop into your BIOS/UEFI during the boot by mashing a key at the correct time (F10, Enter, Esc, F2, or Del etc).
Once in there, have a look around for a "SecureBoot" or "Legacy Boot/Support" options, quite possibly buried in a sub-menu.
Switch that to whatever is seems will disable SecureBoot, save and restart.

Note: This *might* cause any currently installed OS to have conniptions, so you could end up having to switch it back for normal boots.

SecureBoot as an idea isn't bad (only boot things you trust) but the implementation is a bit...err...like be with OpenSSL :-S
There's probably a method to update what your BIOS/EFI trusts for boot but it's not something I've had to deal with and it might be BIOS/EFI specific.
