A yeah it was from a Catalina beta, dated from the 11 august 2019 on my end, so it may not be the latest version, however it has APFS support at least. But it's from a working system.
You can at least flash it and try again the upgrade to Catalina, it's not supposed to fail every time.

If your issue is not related to EFI/BIOS then yes please open another thread (outside the BIOS section).

Hello friend, I didn't know what you did on the CRC32 (Cyclic Redundancy Check), could you help me with my original file I already changed the serial but the other one didn't could, Can the equipment work if we do not modify this parameter???
