laptop install - selected boot image did not authenticate

[router]

Hello, I am trying to install opnsence on a laptop, I burnt the OPNsense-23.1-OpenSSL-vga-amd64.img to a 8gb usb stick but when I try to boot the laptop says "selected boot image did not authenticate" I tried both etcher and rufus but neither will work. How can I fix this? thanks
