my macbook is not booting from my hard drive, its working fine when there is a external hard drive in it with os x on it, and when I install os x through disk utility without the external hard drive, its says its installing but once its finishes it repeats it self and downloads again, any help would be appreciate ?
 
Solution
Have you run disk utility >verify disk on your hard drive while booted from the USB drive?
Also, the hard drive cable is a common failure point on MacBooks and are relatively cheap and easy to replace. If a MacBook boots from an external USB drive with OSX on it and the hard drive checks out then that is the next thing I would look at.
