secureboot

Hi, I want to try Android x86 but I have to disable secure boot to make a dual boot. The problem is if I disable secure boot the surface doesn't turn on. If I re-enable secure boot the surface starts with no problems. I've tried a lot of time. Is there something more I have to do? Thanks

One of our SPro4's is coming up with the following error on boot;- One or more selected boot devices has a SecureBoot violation! Returning to Surface settings. Please verify SecureBoot key configuration and boot device selection. We had Windows 10 Enterprise edition installed.
