2015 Macbook pro starts up then turns off on the apple logo
I just bought a 2015 15inch macbook pro yesterday and I migrated all of my stuff from my old macbook pro, then i changed the name of my user account and i restarted it and it made the chime and went to the apple logo with the loading bar, then got 1/4 of the way then turns off again/goes to a black screen. What can i do to fix this? I booted using the PRAM keys and disk utility says that it cant repair the disk.
MacBook Pro (Retina, 15-inch, Mid 2015), OS X Yosemite (10.10.4), null
