Well, in your particular case you simply "cannot" (in the sense of "easily") get the PBR.
For the record, I'm not sure I fully comprehend the procedure in getting the PBR (unless it stands for Pabst Blue Ribbon, in which case I know how to but just don't want to).
Would it be unwise to move along to the next step with only a copy of the MBR and NOT the PBR?
The MBR you just posted is partially corrupted, hence the disk manager cannot find any LogicalDrive (the PBR is first sector of the LogicalDrive) on the disk/image and HDhacker simply doesnt know which sector to get.
For whatever reasons, the Partition Tables in the MBR you posted are completely 00ed out.
At first sight the MBR CODE is seemingly that of 2K/XP.
You can try running Testdisk (remember to use the /log) since the original disk seems like having being partitioned under XP, reply N (No) to the question if the disk was partitioned under Vista.
Report BEFORE telling Testdisk to write anythng.
