Training Exercise for Joomla BE
When you install with sample data, you begin with content you eventually will not want. What follows are the steps that one might take to remove said content.

To get rid of all this, login as an admin

This is what the backend login looks like

Get rid of the Modules first. So go to Extensions/Module Manager

It’s best to disable modules. Don’t delete them. You might need them later.
Modules to disable:
Banners, Footer, Resources, Key Concepts, Example Pages, Polls, Who’s Online, Advertisement, Random Image, Syndication, Latest News, Popular

Next, get rid of the main menu items

Select the ones to remove, then TRASH them!

Next remove the top menu items

This is what it looks like to remove menu items

Now get rid of the content

You can kill most of the items that come with the Joomla install

Get rid of that Welcome to the Front Page

Trash the sample categories

Now your site should look something like this

Note: In the real world, you would only do this for training purposes. If you plan to build multiple Joomla sites, the best method is to create an empty install, then use that copy of the database for future ones. All of the above clicking is of real benefit when learning a new system as the best way to drill something into your noggin is with repetition.
