MacBook Air 2015 stuck on loading screen after installing update.

I installed updates onto my MacBook Air and when I restarted it the loading bar would just stay in the middle. I've used Disk Utility in recovery mode to "First Aid" my disk, it was fine. I tried booting into safe mode but the loading bar would just hang at the end. I've reset the PRAM, but nothing works. Please help.

*Loading Bar*

MacBook Air, OS X El Capitan (10.11.6)

Reinstall El Capitan Without Erasing Drive

Please be sure you back up.

Restart the computer. Immediately after the chime hold down the Command and R keys until the Utility Menu appears.
Select Disk Utility and click on the Continue button.
Select the indented (usually, Macintosh HD) volume entry from the the side list.
Click on the First Aid icon in the toolbar. Wait until the Done button activates, then click on it.
Quit Disk Utility and return to the Utility Menu.
Select Reinstall OS X and click on the Continue button.
