My guess is that you have incompatible jumper settings on the back of the drives. Check these and make sure that they reflect what the BIOS sees. Also, check your /boot/grub/device.map for consistency. Then use tab completion from the grub prompt to find devices and bootable partitions. > fdisk can see both drives OK.

If the above doesn't get you booting please post your grub.conf, along with fdisk -l. -- Regards, Mick
