Now let me guess, both of the Cd/dvd drives have what we call a 40 pin IDE cable that connects from the back of the drive to a 40 pin IDE connector block on the Motherboard.
Most new boards have phased the interface out since it is so old, replacing it with the Sata data interface. Your out of luck if the board does not have a 40 pin IDE block.
The only other thing to do is buy a Pci add in card to IDE interface ect.
I might aswell just buy a new Cd drive then lol.
But am I able to use a USB to put the iso of my Windows 7 Disk on and use that? Will it be the same as using the cd?
