I bought a new computer that came with a SATA hard drive, and decided I was going to put my old IDE drive on it as master (it has XP and all my crap on it, and the SATA drive is empty) but it won't work. I connected the ribbon cable and the power cable. When I boot up, it says "Error loading operating system" but when I go to BIOS it recognizes the IDE drive. I looked around on google and it said to change "Auto" to "Large" in BIOS, but that didn't seem to do anything. What can I do to get it to work?
