<p>At this point its time to try a different distro. Grab fedora 13 or 14 in a live cd and boot it up. See if it finds both drives. If so please post back the /boot/grub/grub.conf or menu.1st file. There can be two places to define where / is. One is global the other is specific per boot kernel. I suspect the later is wrong as it loads a kernel.</p>
<p>Also try reinstall with windows drive fully disconnected and set for boot drive only new Linux drive. Be sure to fully reformat the drive in the process. </p>
