Personally, I would actually do this:

Get your system back to a factory fresh install and then retry your system.
I don't think the UpdateMBR will solve your problems (I could be wrong).

Just use the patchstick you made to boot the appletv to begin with, and then
grab your backup and follow the instructions (you DID back up didn't you?).
