I just put my computer together, and am using my dads 8 year 2tb hdd, which has vista installed. It booted fine, but vista demanded a startup search or whatever because of the new parts connected to it. It went through identifying a problem, then "fixed it", then automatically restarted. When it restarted I started to get from the BIOS a message saying "Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key". When I went into the BIOS menu the HDD was not showing up. I am getting a ssd soon, but still want to use the 2tb of space.
