Then, after few second, you will get a page like this -

Uncheck the ticked box and click next.

After unchecked, Click Next>

Click:  Yes and then Next>

I am creating a new database that’s why I choosed for 'Create and configure a database' and then click Next>

Here, I am executing root.sh script as Root User -

Now, Go to 'Oracle Database 12c Release 1 Installer' again and Click OK.

Then, You will get this screen. Here Database Configuration Assistant is in progress.

After completing Database Configuration,

You will get -
