Did you make a physical backup of the partitions with dd or just back up the 
files on them? Yes it makes a difference in recovery...

MBR isn't on a partition, that may be your issue.

MBR means "Master Boot Record," so "master MBR" seems like something from the 
department of redundancy department. And if it's working fine I really don't 
understand your problem.

Could you clarify "this" a bit, in terms of what you hope to accomplish, rather 
than how you are trying to do it? I'll try to help, and there are at least two 
people on this list who are better at boot issues than I am, so you can probably 
get a solution once we have an idea what you are trying to do.
