Generally speaking, you do not need to download Recovery Partition, because it is the built-in since OS X 10.7 Lion, when Apple stopped selling boxed copies of its operating systems. However, for one reason or another, you may need to create a one on Mac for backup with USB flash drive.
Here are the steps.
Step 1Download a copy of the “Install OS X” or “Install Mac OS X” from the Mac App Store under the “Purchases” tab. You should match the macOS version with your Mac, for example, the “Install macOS Mojave”. Meanwhile, insert USB flash drive into your Mac.
Step 2Open Disk Utility (in the “Utilities” folder inside the “Applications” directory.), select the “Volume” in the sidebar, and the Volume is in the top part, not underneath.
Step 3Click “Erase”, and make sure it says “Untitled” without changing it. Click “Erase”.
Step 4Open Terminal, cut and paste the correct create install media text into Terminal.
For example, for creating macOS High Sierra, just use the following codec:
sudo /Applications/Install\ macOS\ High\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ macOS\ High\ Sierra.app --nointeraction
Step 5You will need to type your admin account password when prompted, enter "y" and press Return.
Then it will wipe out your flash drive firstly, and then turn it into a bootable installer.
Wait a second, and you will complete the whole process.

Step 1pen Terminal app and enter the following command:
defaults write com.apple.DiskUtility DUDebugMenuEnabled 1
Step 2Open the Disk Utility app. Select “Debug” in the menu bar at the top > “Show every Partition”.
Step 3At the top, select “Recovery HD” > Click the Mount icon to make it active, and you will see it no longer grayed.
Step 4Secondary-click on the mouse and then selecting “Erase” to delete partition recovery.
Step 5Select the “Partition” tab > Click to select the small Recovery HD partition > Click the minus symbol, beneath, to remove it.
Then a conformation dialogue will pop up, and you just need to read it and confirm the action to delete it.
