Perhaps the BIOS has a conflicting setting or is trying to force
something. If hdb is there but it can only be found from a running linux
rescue disk, it means the bios itself is likely denying its existence;
linux does not need the bios after initial boot stages, but as far as I
know all boot loaders do need the bios to agree for the initial bootup.
