I have a rather similar dual-boot system with both booting into W8.1. I occasionally get similar problems to yours, for no apparent reason, when either system will boot, but can't see the other drive. Try replacing, or re-inserting, the sata data cable. I've found that pulling it out and back into the motherboard sometimes helps---maybe it's a loose mobo connection.
