I am confident that there are several boot managers, likely one for each of those four OS's, that can find multiple bootable OS drives/ slices/ partitions and allow you to boot the OS of your choice. But, my experience is that keeping them all running is an exercise in "infinite bug propagation" I can afford US $45 mobile racks and US $20 SSD's. My time and mental bandwidth are more valuable. I would remove three of those drives and run one OS at a time. David
