I assume the DVD drive is an IDE drive. If this is the case then you probably need to install the SATA drivers by hitting F6 on the windows install disk when it first starts. Alternatively ensure that the SATA controller in the BIOS is set to IDE mode.
Yes the DVD is IDE, but I'm using a SATA adapter so it is plugged into a SATA port. Do I still need to install SATA drivers? Tried changing the SATA controller to IDE but no help.
