Reboot and select proper boot device

[Trentobean]

I started up my computer this morning, and it gave me a blue screen error, which was VIDEO_SCHEDULAR_INTERNAL_ERROR. After the computer restarted it gave me the insert proper boot device. Every time I restart it gives me this. I've tried making it the primary boot device in bios and even tried manually booting off it and it doesn't work. I haven't had any hardware changes recently. Any help is appreciated.

have you had any storms lately? seems like you either have a corrupt bios, bad sata controllers or something happened to your hard drives.
