It was probably plugged in for booting, and so it's likely /dev/sda,
demoting the system drive to /dev/sdb.

I think I saw in a previous post of yours in June that you have not
only an encrypted system but also physical volumes and that lvm stuff.
Perhaps you might post the contents of the first menuentry stanza in
your grub.cfg, and confirm that your volumes are contained in an
outer encrypted partition (if I expressed that correctly). This
might help the OP boot the system manually and recover the blue
Grub menu.
Cheers,
David.
