gateway nv76r31u , No Bootable Device, Hit any Key

[negmaron]

My gateway nv76r31u is displaying No Bootable Device, Hit any key. When i hit enter it goes to the boot manager but there are no option listed there. I tried access the bios using f1, f2, del but no of them worked. Can someone please assist.
Thanks

Enter the bios and see if it is seeing your harddrive. It might just need re-seating or, at worst, replacing.
