ssd not showing in bios boot order

Gday there i can boot up my PC by tapping f 11 i can see my ssd and my Samsung hard drive there i tap ssd drive and it boots ,but i have to do this painful process every time i boot up.
my mobo is a z77 extreme 4 all was fine until i followed an over clock guide and my bios must have reset it self when i went past the sweet spot.I did find a solution as a cmd prompt make ssd boot priority 1 in the cmd prompt,i found this in Google but now i cant find it again.Can some one please advise me what to do.:)

Have you tried going to the BIOS and setting the SSD as first in the boot priority?

G'day as I said the ssd is not in the bios thanks for your reply

ok all has been fixed thanks to my friends at atomic,it seems all i had to do was shutdown,pres reset button on the back of the pc,after i removed the power cord .plug back in hit power and all is sweet once again,thanks for trying to help me bcopter
