Which method are you using?
1. Start up from macOS Recovery
To start up from macOS Recovery, turn on your Mac and immediately press and hold one of the following combinations on your keyboard. Command-R is generally recommended, especially if you never installed macOS Sierra 10.12.4 or later… How to reinstall macOS - Apple Support
Command (⌘)-R
Install the latest macOS that was installed on your Mac.
Option-⌘-R
Upgrade to the latest macOS compatible with your Mac.
Shift-Option-⌘-R
Install the macOS that came with your Mac, or the closest version still available.
2. Decide whether to erase (format) your disk
If you need to erase your disk before installing macOS, select Disk Utility from the Utilities window, then click Continue. You probably don't need to erase, unless you're selling or giving away your Mac or have an issue that requires you to erase. Learn more about when and how to erase.
3. Install macOS
After starting up from macOS Recovery, follow these steps to install macOS:
If your Mac restarts to a setup assistant, but you're selling or giving it away, press Command-Q to quit the assistant without completing setup. Then click Shut Down. When the new owner starts up the Mac, they can use their own information to complete setup.
If you never installed macOS Sierra 10.12.4
If macOS Sierra 10.12.4 or later was never installed on your Mac, macOS Recovery works differently:

First, I used Command (⌘)-R to erase my disk then install OS since It failed to install OS.
Hello,
I did, now I got this error, it said "An error occurred while preparing the installation. Try running this application again."
I do not know what to do now. Any suggestions.
Thanks,
If you're using Wifi, can you try an Ethernet connection?
Hello,
I plugged an Ethernet still get same error error. It’s mac 2015 i5.
Thanks?
Oh! I used this option and re-installed successfully with Option-⌘-R.
Thank you for you help, and I really appreciated.

Great to hear Vinh, take care my friend, :)
Hello,
Please let me know how to download Norton 360 for my Mac? Can I download direct from Norton.com?
Many thanks,
Vinh.
You could, but I advise anything but Norton....

…I don’t install anything?
Correct, I don't think you need to, but you know your situation better than I do.
Thanks so much!
Great to hear, glad I could help, take care my friend! :)
