Q: Mac Pro el capitan: user name and/or pw not accepted: how do I boot up to correct this

I recently acquired a 2009 Mac Pro firmware 4.1 loaded with an update version of el capitan.  I immediately changed the admin password but did not change the admin username nor did I change boot from automatic to username/password until today. NOW it will not accept any combination of username / password.  How do I overcome this goof to change the username and password.

Mac Pro, OS X El Capitan (10.11.6)

    Erase the drive and install the original version of OS X that came with the computer or a retail copy of Snow Leopard.

    You can purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard - Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.

     

    After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store.

     

         Snow Leopard General Requirements

     

           1. Mac computer with an Intel processor

           2. 1GB of memory

           3. 5GB of available disk space

           4. DVD drive for installation

           5. Some features require a compatible Internet service provider;

               fees may apply.

           6. Some features require Apple’s iCloud services; fees and

               terms apply.

    With access to the App Store you can download Sierra using your Apple ID and password along with any other apps you would care to acquire. You may also re-download apps already purchased by you under your Apple ID.

     

    Snow Leopard Erase and Install

     

         Be sure you back up your files.

     

    1. Insert Snow Leopard DVD into the optical drive and restart the computer.
    2. Immediately upon hearing the chime hold down the C key.
    3. Release the key when the Apple logo appears and wait for the loading to finish.
    4. After the installer loads select your language and click on the Continue  button. When the menu bar appears select Disk Utility from the Utilities menu.  After Disk Utility loads select the out-dented disk entry from the side list (mfgr.'s ID and drive size.)  Click on the Partition tab in the Disk Utility’s right window.  Set the number of  partitions to (1) from the drop down menu. Click on Options button and select GUID, click on OK, set the format type to MacOS Extended, Journaled. Finally, click on the Apply button.
    5. After formatting has finished quit Disk Utility.  Continue with the OS X installation and follow the directions.
    6. When the installation has finished the computer will restart into the Setup Assistant. After you complete the Setup Assistant you will be running a fresh installation of Snow Leopard. Open Software Update and install the recommended updates.
    7. If you are planning to sell or give your computer away, then do the following: After you reformat your hard drive and reinstall Snow Leopard, the computer restarts to a Welcome screen. To leave the Mac in an OOTB (Out Of The Box) state, don't continue with the setup. Instead, press Command and Q keys to shut down the computer. The Setup Assistant will guide the new owner through the setup process after he/she turns on the computer.
    8. Download and install Mac OS X 10.6.8 Update Combo v1.1. if needed. It is not needed if you are selling or giving away the computer.
