Install Oracle Linux but not getting GUI windows

Get GUI window after installing Oracle Linux on VM. I am getting command shell for login or password:

1. Login with root user and password or otherwise use sudo command to install the GUI packages in your Linux system:

yum groupinstall "Server with GUI"

OR

sudo yum groupinstall "Server with GUI"

2. It will install all the GUI packages and reboot the server.

3. After installation, you need to set the default mode to GUI for login into GUI window otherwise for manually you have to fire “init 5” command to switch to GUI if needed.

-- For Manually GUI 
-- login with root user or sudo and run following command:
init 5

-- For permanent switch to GUI window on start:
systemctl set-default graphical.target
