Q: El Capitan won't finish installation

I've downloaded El Capitan and the installation seemed like it went alright. Until the progress bar on the restart reached about 80% and just sat stagnant for hours. I've since tried many suggestions from community forums. I've tried starting up in safe mode, it won't actually do it. Gets hung up on that same progress bar. I've started up using cmd + r and ran first aid on the hardrive. Everything came back fine. Tried reinstalling in that same Cmd + r menu, didn't help. I've tried anything and everything I could find within the last 48 hours between work and what free time I have had. I only even wanted to update from Mavericks because something I tried to run required the newest OS X. Is there a way I can just re-do the entire download and install of El Capitan entirely? I've no idea what would even be causing this. Everything ran perfectly fine besides the one game requiring the upgrade.

 

This is on a mid 2011 iMac 27" so it's well beyond the system requirements.

iMac (27-inch Mid 2011), OS X El Capitan (10.11.4)

    First, update the firmware if you haven't already: Computers that can be upgraded to use OS X Internet Recovery.

     

    Restart the computer. Immediately after the chime hold down the Command-Option-R keys until a globe appears. The Utility Menu will appear in from 5-20 minutes. Be patient.

     

        1    Select Disk Utility from the Utility Menu and click on Continue button.

        2    When Disk Utility loads select the drive (out-dented entry) from the side list.

        3    Click on the Partition tab in Disk Utility's main window. A panel will drop down.

        4    Set the partition scheme to GUID.

        5    Set the Format type to Mac OS Extended (Journaled.)

        6    Click on the Apply button, then wait for the Done button to activate.

        7    Quit Disk Utility and return to the Utility Menu.

        8    Select Reinstall OS X and click on the Continue button.

    This did help. I hate that it had to come to this due to having not backed up in a while but that's my fault. I've never had an issue updating an OS with Mac. Thank you for the information.
