There's no such thing as first, second, third, os. hdX,Y refers to the
harddrive/partition.

So your BIOS boots from sdb. Your kernel line should look like this:

kernel (hd1,0)/vmlinuz blahblah...

or

root (hd1,0)
kernel /vmlinuz blahblah...

Now you lost me. sda is PATA, sdb is SATA. What's sdc?

Can you post the output of:

$ sudo fdisk -l | grep ^/

and:

egrep ^root\|^kernel /boot/grub/menu.lst

?

Thanks.
