I would have said:
root (hd1,0)
kernel /vmlinuz root=/dev/sdb3
boot

grub images should be in a directory in /boot  called boot so it should
be /boot/boot/grub/*

but this doesn't explain the error message you get!

you can try using the tab completion in the shell to figure out which
drive is the right one.

e.g
type root (hd1,
then hit tab and it should list all the partitions on that device, so
basically make sure it looks like the drive you think it is.
