Disk utility first aid did not work

applied first aid to all files through device utility and restarted Mac. The apple logo and progress bar appears, however does not boot up. Prior to this issue I installed netgear usb controller, restarted and this issue started. All peripherals have been removed prior to restart.

How to use safe mode on your Mac will the computer boot in Safe Mode ?


Safe mode may help you resolve or isolate problems that you’re having with your Mac.

When you start up in safe mode, your Mac prevents some software, such as startup items, from loading, and it performs a check of your startup disk. Your Mac may take longer to start up because of the check.
