I'm having some issues with imaging a certain machine where it says, "there are no task sequences available for this machine" and I've read that it can be caused by two machines with the same System UUID(And that's the same thing as the SMBIOS GUID?) in SCCM. I'm trying to create a query that prompts me for the system UUID and shows the machine(s) with that are associated to it. I found an article that shows how to do it in SCCM 2007 by choosing

Attribute Class -> System Resource
Attribute -> System UUID

However there isn't a system UUID option under attribute in 2012. There is the BIOS GUID under resources. Is that the same thing as SMBIOS GUID which is the same as System UUID? There are so many different UUIDs and to be honest, I don't know enough about them yet.
