With my first Drupal installation I have to struggle to change the default home page. This is relatively a very simple task, which I later found out.
To change the default home page in Drupal
1) Create a Home page from Create Content->Page
a) Enter the Title
b) Enter text in the Body (you can modify it later)
c) Under URL path settings enter Home (or any similar name of your choice to identify it, which you will require in 2nd step)
d) Under Publishing option check the Published and leave rest of check boxes unchecked
2) Under Administer->Site configuration->Site information
Scroll down to Default front page:
Enter Home (or whatever name you have given in step 1.a)
Click Save configuration and you are done.
