    It is highly unlikely that you do not have a recovery partition.

    What is more likely is that you have one but it is hidden in your startup manager you get when you startup with option key because your installer created a core storage volume.

    Case 1: If you have a hidden recovery partition

    In this case you have 2 remedies.

    1. To get to the recovery partition startup with cmd+R.

    2. If you prefer to see the recovery partition in the startup manager, revert the core storage volume as follows:

    Run these 2 commands in terminal.

    diskutil cs list

    and then

    diskutil coreStorage revert lvUUID

    where lvUUID is the last lvUUID reported by the previous Terminal command.

    Then restart for everything to get back to normal after you have run these commands in Terminal.

    Now starting up with option key will reveal the recovery partition in the startup manager.

    Case 2: You really don't have a recovery partition

    This is rare but can happen if you restore from a CCC clone. In this case you can create a recovery partition yourself as follows:

    1. Download the Lion Recovery Update from https://support.apple.com/kb/dl1464?locale=en_US . (And before you ask, YES. I mean LION recovery update!) Make sure it is in your downloads folder. If you still happen to have the Sierra full installer somewhere, right click on it and click Show Package Contents. Go to Contents/SharedSupport/. Copy the InstallESD.dmg file into your Downloads folder. If you don't still have the full installer, you can get it again by redownloading from your purchases tab in your mac app store.

    2. Download and decompress the file recovery.sh.zip from http://4unitmaths.com/recovery.sh.zip and move recovery.sh into your Downloads folder if it's not there already.

    3. Open Terminal and type the following commands:

    chmod +x ~/Downloads/recovery.sh
    sudo ~/Downloads/recovery.sh
