WytWun,
Your suggestion was the answer. The UEFI bios on my Ryzen machine was "Mostly" set to legacy. However, the Boot Device control was set to Legacy and OPROM so changed it to Legacy OPROM only. But I don't think that was the fix. The other change was the OS Type under Secure boot. This was Windows UEFI so I changed it to Other OS and reinstalled Linux on the SSD. Moved the SSD to the target system and it now boots normally on the SSD. Thanks again.
