They're on sata1 and sata2 (or maybe 0 and 1, who knows). The d: is my old c:, and when installing the new c:, it set up a boot menu to select. But when I pull the d: vista won't boot anymore. I keep forgetting to write the message down, but it's fairly unspecific, please insert bootable media or something. I did msconfig and deleted the reference to the d: and clicked make permanent, reboot, still won't boot if I pull the sata to the d:. Any ideas? I'm trying to avoid running repair off the god forsaken vista install dvd and having to scrounge drivers to stick on a thumb drive, cuz my mobo is swank like that.
