Until this morning, my computer worked just fine. Then I heard a small bumping sound out of my computer box, windows worked for a few seconds more then restarted and i got this message. 'Reboot and select proper boot device or insert boot media in selected boot device and press any key_' I read over the internet that I should go to the Bios menu and detect the boot drive. Went there, but the only thing I can detect is my floppy and CD/DVD drives. I have 2 SATA harddrives, one of them has windows on. Don't know what to do to make my computer work again, let alone detect the hard disks. I really need help here. It's the first time this happens to me.
