It looks as if you asked a question very like this in February, to which there were two followups, but nothing back from you about how you're booting this machine, UEFI or legacy BIOS, and how the disks are partitioned, MBR or GPT. This may make people reluctant to help, as they may feel they are wasting their breath. My only advice at this time would be to find a better method to identify your disk partitions than their kernel names, /dev/sd[abcd]: so LABELs, PARTLABELs or UUIDs. Cheers, David.
