If you have an UEFI issue with certs, the USB drive would fail to boot from a security violation. You can temporarily disable Secure Boot mode in BIOS to see if that makes a difference or not. Presuming it doesn't, your problem isn't the Secure Boot certs.
Typically if a bootable USB drive can't see a storage device, it implies the boot image is missing the required storage controller drivers.
The other reason for not booting is you have the wrong version of the boot file.
