The blue screen is not a current issue, this was one of three old HDDs that I had and I only plugged in the broken one to see what it would do, I already knew it was broken. I messed around with every possible jumper setting combination and most of the time I was trying to get these to work I didnt have anything else hooked up to it, no CD/DVD or floppy so it isnt really a boot order problem. In the Bios the boot order show everything as not installed. Neither of the BIOS have any auto detect setting but instead just on/off for the IDE and SATA connections.
