31.   Once packages and dependencies have been worked out Red Hat will begin copying          
         packages to disk.


 
32.       Once all packages have been copied to the VM disk, you will see the screen below

 
33.       Remove the ISO mounted as CDROM

 
34.       Click [Yes]

      User Name: root
      Password: the one you set previously for the root user.
 


That is it guys, at this point your Red Hat is fully installed, up and running.
