Question: Macbook Pro Deletion For selling

I have a 2011 MacBook Pro, which has MacOS Sierra installed, I did what I normally do when going to sell and only laptop, backed up all my information on my external hard drive, and hit command R when rebooting, now when I start up it states- "macOS could not be installed on your computer. The path /System/Installation/Packages/OSInstall.mpkg appears to be missing or damaged. Quit the installed to restart your computer and try again."

Which I have done several times. What do I do!? Help!? Thanks!

MacBook Pro, iOS 11

How To Do A Factory Reset

Selection A should be used on computers that came with Lion or later when factory new. Selection B is for Macs that came originally with Snow Leopard or earlier.

A. Factory reset your Mac - Apple Support

B. Factory Reset Your Pre-Lion Mac

Follow these instructions until you get to Step 5: Factory reset your Mac - Apple Support. At Step 5 you will need a Snow Leopard DVD or the installer disc that came with the computer.

  1. Boot the computer using the Snow Leopard Installer Disc or the Disc 1 that came with your computer. Insert the disc into the optical drive and restart the computer. After the chime press and hold down the "C" key. Release the key when you see a small spinning gear appear below the dark gray Apple logo.
  2. 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 hard drive entry from the left side list (un-dented entry - mfgr.'s ID and drive size.) Click on the Partition tab in the Disk Utility main window. Set the number of partitions to one (1) from the Partitions drop down menu, click on Options button and select GUID, click on OK, then set the format type to MacOS Extended (Journaled), then click on the Apply button.
  3. When the formatting has finished quit Disk Utility. Proceed with the OS X installation and follow the directions included with the installer.
  4. If you are planning to sell or give your computer away, then do the following: After you reformat your hard drive and reinstall OS X, the computer restarts to a Welcome screen and asks you to choose a country or region. If you want to leave the Mac in an out-of-box state, don't continue with the setup of your system. Instead, press Command-Q to shut down the Mac. When the new owner turns on the Mac, the Setup Assistant will guide them through the setup process.
