It appears that the listing is showing physical drives at 02, 03, 08, 09, 0A, and 0B –*more than 3 perhaps due to partitions or boot sectors. [Note: 0A and 0B are legitimate hexadecimal numbers.] I would remove all others, and then do a boot dump again to see the results. It may take a few times to get it right. If the option says "DevPath - PciRoot" then it needs to be removed. One time I had to remove ALL of the entries on my machine, so that the boot dump showed no entries at all. When I rebooted the computer, all was well. I am no expert on why this works, or exactly what it does, so I can't say this will for sure work with your system. I just found the technique useful for problems that seem to occur with Clover.
If your backup drives contain boot sectors with an installed boot loader (like a clone of your startup disk), you will continue to run into problems.
