FOr the movement of jumpers, you will have to follow the diagram that's on the hard drive. I suggest moving the HDD to Master.
The Primary IDE cable will plug into the hard drive which will boot first. This is the C: drive. This hard drive will plug into the very end connector of the ribbon cable. This "boot" hard drive will have its jumpers set as "Master." These jumper settings can be found printed directly on the hard drive case. The Secondary IDE cable will plug into the second hard drive, and DVD-ROM drive. In this scenario, you 'll plug the cable into the second hard drive, which should be jumpered to "Master", and the CD-ROM drive, jumpered as "Slave." (the middle connector on the ribbon). So both hard drives should be connected at the very top of the cable (Master).
