if dont work: try with another ide input on the motherboard. (btw, the blue input in the cable goes to the motherboard)
try 2 single cables. set the HDD to master and the CD drive to cable select. if that dont work: try setting the Cd drive to slave.
then try to swap the 2 ends of the ide cable to eche others ports on the motherboard. one of the ide ports on the motherboard is the premier port.
the try the thing above again.
Something else to look at is the number of wires in your cable. If it is an older CD drive I have found that it can have issues with the 80 wire ones that most hard drives require, it took me three hours of swearing at my server to figure out why it wasn't recognizing my CD drive. Try using one of the 40 wire ones instead. (Sorry for my lack of technical terminology, I'm not really much of a hardware guy)
Also, does your BIOS allow you to boot from USB? because if you can do that just make a bootable flash drive with the disk image from one of the boot CD's you are using, that usually saves me a lot of headache, but doesnt work on older motherboards.
