I am sorry but your not making any sense. Care to elaborate some more ?
hold down the option key when you boot it up and it should give you the option to select macintosh HD. Click that and it should boot normally into os x
It sounds like you need to format and reinstall OS X, but it looks like you are doing that already

Ya, that is alright, you just have to be patient, and usually the calculations are WAY, WAY off.
I was using my macbook with external display and i was updating the software which came two days ago efi one ...... It said restart needed then during boot a circle with a slash appeared before apple logo
And osx utilies started ?
Sounds like your OS was somehow damaged during that efi update. Try a command-option-r (hold all three at once) boot to internet recovery. Once in the recovery screen start disk utility and run repair disk on the drive and see if that helps. Tell us what you see when you run the disk repair.
Nothing about that efi update should hurt your OS. It could be you have a drive failure imminent and it just picked this time to go bad.
Disconnect the external display and run off the MacBook when testing this.
