Yet another GRUB error 17
I am attempting to triple boot Ubuntu, Windows 7, and Backtrack 4. Win7 and Ubuntu are both booting and working properly, but after trying a number of configurations for GRUB I cannot boot Backtrack. Everything I attempt seems to come back to one problem and result in the same error: Error 17.
sda contains both my Windows and Ubuntu partitions...
Code:
Disk /dev/sda: 250.0 GB, 250059350016 bytes
255 heads, 63 sectors/track, 30401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

...while sdd contains the Backtrack partition.
Code:

Can anybody point me in the right direction to getting sdd mounted? Is it even possible to boot from a separate hard disk the way I am attempting to? I know chainloading is a method typically used for unsupported operating systems, but is this a situation where it should be used?
