Hi,

It took me a while to figure out what I was doing wrong.

I was trying to boot with iPXE, but it just wouldn't !

And the bios firmware should be a lot clearer about the problem not just say "Access Denied"
On this already very difficult task !

I can't find how to disable this easily.

Easiest way I found is to boot the VM and immediately hit ESC

Go to Device Manager

Then secure boot configuration

And uncheck Attempt Secure Boot

Then press F10 to save

Then leave with ESC -> ESC -> Reset

And THEN it will boot
maybe
if you've been nice this year

This setting should really be somewhere in the VM creation dialog

To boot via PXE, either the PXE server must support Secure Boot (which you don't want to set up), or you can choose disable Secure Boot when creating the VM by disabling it as follows:
