I recently upgraded my entire system, which included a new SSD and a fresh install of windows. I kept my old standard drive (which is in perfect working condition) and it is plugged into SATA 2 (my new SSD is in SATA 1). BIOS and Windows 7 (from the SSD) both recognize the drive, and all my files are there and accessible. However, when I go into BIOS and select it as the boot device, it fails, I get a really quick flash of a blue screen, and then it reverts back to booting from the SSD. I figured I could just select it as the boot device and it would fire up and I'd be running the new computer from the old drive...is that not the case? Does it change things since its a second drive? I don't plan on using it much, maybe only for the occasional forgotten file....
