A Safe Mode boot deletes system caches that may help after an OS X update or upgrade.

Top left corner of your screen click the Apple  > Shut Down.

After your Mac shuts down, wait 10 seconds, then press the power button.

Immediately after you hear the startup tone, hold down the Shift key. You should press the Shift key as soon as possible after you hear the startup tone, but not before.

Release the Shift key when you see the gray Apple logo and progress indicator.

Once you are in Safe Mode, go back to the Apple  menu. From the drop down menu click: Restart

Hi, had same problem, after upgrade to El Capitan: was unable to boot any way not even safemode. Always loop back to the utilities. Finally tried to reset the NVRAM by holding option cmd P R (four buttons) till the MBP rebooted for second time and then loaded my OSX 10.11. So far works haven't rebooted yet 😉

Same problem here. I get hung up on the Apple logo screen with progress bar and a strange pattern covers the screen. I've reinstalled three times and it acts normal after the reinstall until I restart. Every time so far, I've gotten that screen. Resetting the NVRAM doesn't work. Safe Mode doesn't work. Disk Utility tells me that everything is fine.
