What do I do???
MacBook Air, OS X El Capitan (10.11.2)
Hey CaS12345HI,
I understand that you are getting an error symbol upon startup. Is it like the one below. If it is, the best thing to do is to reinstall OS X to resolve it.
Prohibitory symbol
When you see a circle with a slash symbol instead of the Apple logo, it means your Mac couldn't find a valid System Folder to start up from.
If you're using your Mac at a school or business, it might be trying to start from the wrong version of OS X. Contact your IT department for more help.
If this is your personal Mac, try reinstalling OS X by using OS X Recovery.

Now if you run into issues installing, take a look at the next article that goes into resolving startup issues with either OS X Recovery or fsck.
