Hi I changed my PC case, motherboard, installed another dvd drive and Hard disc. I installed windows XP onto one of the HD which is a SATA drive ( connected to onto SATA 1) and connected one dvd drive (primary) onto IDE connector 1, however when I connect the 2nd HD via IDE connector 2, I keep getting this error message "NTLDR is missing". When I installed both the DVD drives on another MB, the PC did not start. I don't think my configeration is correct and I would like to find out the correct configeration please (i.e which IDE connectors 1 or 2 to use for dvd drives and HD drive and SATA connectors 1 or 0) and which one should be master and slave), BIOS settings and set up please and how to deal with this error message. The specs are: Gigabyte GA-81PE1000-G motherboard P4 3.2, 800FSB CPU Corsair TWINX 3200 C2PT memory ATI Radeon X700 PRO 256MB AGP X8 Hitachi Deskstar 7K250 160GB SATA - Windows XP installed Hitachi Deskstar 80GB IDE - ?
