    Put the DVD in then reboot and hold the C key... that should get you to the installer where you can use Disk Utility to erase the drive and install.

    Is this the grey installer DVD that came with it from the factory? Because those DVDs are model specific.

    My iMac is late 2009 and recently my Mac would take too long to boot up, eventually it stopped booting up. My only option was to boot into recovery mode. On recovery mode I decided to wipe my Mac since it some how reached its storage limit, after that I installed OS X base system and now I cannot reinstall macOS due to my disk being locked. Everything except First aid, Info and (Partition, which I cannot do anything with at all) is grayed out in disk utility.

    That sounds like your drive failed and will need to be replaced. That base system you see there is a virtual drive in memory the installer sets up and is normal.

    You cannot erase the entire disk like that because you are booted to the recovery partition on that same disk. Can you click just below that where it says 160GB and erase from there?

    From recovery open Terminal from the Utilities menu and run each of these two commands and tell me the output of each command.

    Code:
    diskutil list
    
    diskutil cs list
    What lead up to this and why are you reformatting?

    Are you able to get to Terminal and enter the command? It should at least give an error message.

    When in recovery, what message to you get when you try to erase the lower 160GB volume?

    Can you explain what lead up to all this and why you are reformatting to begin with?

    So I went to erase and reinstall OS X. When I go to reinstall OS X my
    Only option is to choose to reinstall it on OS X Base system. That is greyed out and says this disk is locked.

    How would I go about fixing this so I can reinstall OS X.

    P.S. there were no issues with my Mac. Just reset every year to keep clean

    That base system is a virtual image of the installer that is loaded in memory and that part is normal. But otherwise, can you see the internal drive in Disk Utility?

    What year and model Mac are you using?

    Try using Internet recovery. Hold command-option-r at boot and select your wifi then you will see a spinning globe while the recovery utility downloads. Then the recovery screen will come up. From there start Disk Utility and tell me if you can see the internal drive. If you cannot, you likely have either a failed drive or a bad internal drive cable.
