1. Set the bad disk as slave by not putting any jumper clip and connect the IDE cable.
2. Check whether the power cable to the bad hard disk is connected properly. I know many people who forget that
3. Power on the system and go to the BIOS by hitting del (or F2, depends on your motherboard)
3. See if the bad disk is getting detected or not in the first place. If it is not showing in the BIOS, press F10 to save and exit and get professional help, I don't think there's much you can do.
4. If you see the disk then set the booting hard disk as your good hard disk, press F10 to save settings and press enter
