Merge D and E

Can you elaborate on that? The UUID format is 5 pieces of 4-2-2-2-6 bytes;
example:
123e4567-e89b-12d3-a456-426614174000
Why would you merge the last two?

There is actually an issue with the GUID. For example, I get this:

Variable - 8be4df61-93ca-11d2-daa-00e098032b8c - SecureBoot

part D is wrong; it should be aa0d (the full GUID is 8be4df61-93ca-11d2-aa0d-00e098032b8c)
