Dumb question - does your BIOS know about the IDE drive? If not,
then chances are you will not be able to boot from it. You may have
to make space for the /boot directory on the SATA drive.

If your BIOS does know about the IDE drive, running "grub-install
--remap" may help. You may also want to try running "geometry
(hd2,0)" and "geometry (hd3,0)" just in case the BIOS is skipping
numbers when mapping drives.

With the drive being /dev/hdk, it sounds like the drive is on a
controller card, and not off the motherboard... Is this the case?
