ASUS G75jh ''reboot or select proper boot device''

[esc_24]

Yesterday I was using my laptop . then suddenly it hanged and froze on me . so i turned it off by pressing the power button . when i started it again it says ''reboot or select proper boot device'' . and the only boot option i have is p1: dvdram* p2:sata something which i believe is the second hdd ? and when i go to sata configuration that sata 0 is empty . and sata 1 is the dvdram. any help would be appreciated ! thanks .
