So, I’m having an issue that I can’t quite figure out. Just reinstalled my OS on a SATA striped raid (2x160gb’s) on the motherboard SATA ports. Installed without issue (in fact I’m using right now to type this). I also have a 1 TB SATA drive for just storage that is ran off of a PCI SATA card. I only have 2 SATA ports on this board. Here is the problem; when I plug in the 1 TB drive and boot the comp I get a boot disk not found error. With it unplugged, boots up just fine. I believe that the BIOS is confusing the drives but I cannot figure out how to tell the BIOS to pick one over the other. My PCI can does not have raid capability if that matters. If I need to post more info I can. I’m clearly a bit of a novice here so all help is appreciated.
