This way you will have to connect the disk to your Mac everytime you run Disk Recovery Assistant. You may select an external disk if you have one.Click OK, then select the primary disk partition where the OS X install resides, from the selection before you.In addition, the script will prompt you with the OS X version you are currently using. You will be prompted to create a backup, and I encourage you to do so using Time Machine, just in case something goes wrong. To create the partition HD, follow these steps. To begin with, you will need the OS X installer from the App Store (be it Mavericks, or Yosemite or others) and you will also need the Recovery Partition Creator (RPC), an AppleScript that enables us to create the partition in a friendly way. Here’s how I sorted out this issue without Internet Recovery, and it’s not as complicated as I first thought. But, it requires an Internet connection, so you are out of luck if you have poor or unreliable Internet connection. It lets us perform the disk recovery, then fix and reinstall OS X from Apple’s server. Internet Recovery is a feature addition since OS X. To verify this, I ran diskutil list in Terminal but I can’t find the Recovery HD partition. I later on figured out that this happened because the Recovery partition is missing somehow.

However, instead of coming to Disk Recovery Assistant, I was directed to the Internet Recovery, which was unusual. So, as usual, I reboot OS X and held Cmd + R to access the Disk Utilty in OS X Recovery to fix it. While I was doing maintenance for my OS X, using the Maintenance app, the app told me that my disk partition needs to be repaired.
