1/ The 30GB HDD space on FSM is perfectly normal, it won't detect all your HDD in FSM, so don't worry about it.

2/ as @baileyscream mentioned, use Rogero 3.4 and not 3.5, 3.5 is a PoC and is buggy, it might even be why the dual boot won't work (I don't know exactly how it works but it might be messing with the BD firmware)
