Situation is: old motherboard don't have SATA connector and had plugged on it one HD on the primary IDE and one DVD drive on secondary IDE connector. I wanted to connect new SATA HD (WD 5000 AAKS ) and bought IDE-to-SATA adapter, plugged it on the primary IDE, add new HD and moved old HD into the secondary IDE like master drive (DVD is slave). I bought the new HD without jumper and I don't think I need it because it is the only device on the primary IDE connector. Old HD and DVD has correctly set jumpers. When I start the computer it don't recognize anything and can't boot. If I remove the new HD it recognize both HD and DVD and everything is ok.
Thank you in advance
