Macbook reinstall? Bug when I start my MacBook

Hello everybody

I have a problem with my Mac Book Pro.

When I start my computer, there is not my principal page. I wait 30 seconds and there is : "OS X Utilities" on my Mac. I can... "Restore from Time Machine Backup", "Reinstall OS X", or access to "Disk Utility".

I have already reinstall OS X but each Time the chronometer come "1h10 to the end" when it cmes down to "9 mins to the end". Each Time !!!

And when I check "Disk Utilities", I have clicked to "Verify Disk" and... No problem detected.

Please! Thank you so much
