This has nothing to do with coreboot, the message is from the UEFI payload (Tianocore/edk2). It's telling you that whatever boot device it is trying to boot (and it tells you in the error msg) does not contain a UEFI-bootable 64-bit OS. If you didn't install ChromeOS Flex to your internal storage, then that is why (since ChromeOS proper is not UEFI-bootable).
