Macbook permanently crashes while updating to El Capitan I downloaded, and then started installing OS X El Capitan on my MacBook Pro. But I think it just stacked i think. So I turn off mac, and then turn on again. Every time when I try to login on my account I have a crash as following:



Is there a way to reset this and download again? 

I am really appreciate for any help. I do not know what to do.
I did it with simply press Cmd + R, and then press off. Cmd + R I kept pressed until Apple logo appeared, then I get into Install OS X mode. There you should once again connect to the internet, choose language,and waiting for new install.
