Asus P8Z68-V Pro - no longer booting to SSD drive

Question for ya: When i start up my new PC it isn't recognizing my SSD anymore to boot from. When I enter the BIOs on start-up and go to the boot menu it's there for me to load on. I have to do this ever time I turn it on otherwise is says there isn't a OS found. Any Ideas?

Under the advanced tab where you have the boot menu there are two places where you have to make sure that the SSD is listed first. The actual boot sequence and the list of available hard drives which is usually found just under where the boot sequence is. Also did you enable AHCI mode?
