So far the Norton Boot Recovery Tool is not useful for removing rootkits or bootkits. The technology is very little different from Norton itself, so if Norton is allowed to remove infected system drivers, the boot tool will do likewise, which can cause the machine to become unbootable. It also has to have access to the internet to download definitions, which is also problematic.
They are working on it to increase its usability, and it has removed Mebroot on test machines.
The downloadable Norton Power Eraser also requires internet access in order to work, and may identify rootkit files, but is also
subject to false positives. It does produce a list of infected files, but if used by an inexperienced user, is also capable of removing system files.
Neither one is capable of finding or swapping out infected system files.
There is more information available on both of these tools on the Norton forums.
