For new installation of RHEL 7 ,GUI doesn’t come with default installation.
If you do not click on the “Software Selection” link and pick “server with GUI” then there will be no GUI after reboot, only “Base Environment ” will be installed.
To enable GUI after system installation, you can use following method.
Installing the environment group “Server with GUI”
1. Check the available environment groups :
]# yum grouplist
Loaded plugins: langpacks, product-id, search-disabled-repos, subscription-manager

The above will install the GUI in RHEL 7, which by default get installed to text mode.
3. Enable GUI on system start up. In RHEL 7, systemd uses ‘targets’ instead of runlevels. The file /etc/inittab is no more used to change run levels. Issue the following command to enable the GUI on system start.
To set a default target :
# systemctl set-default graphical.target
To change the current target to graphical without reboot :
# systemctl start graphical.target
Verify the default target :
# systemctl get-default
graphical.target
4. Reboot the machine to verify that it boots into GUI directly.
# systemctl reboot
Installing core GNOME packages
“Server with GUI” installs the default GUI which is GNOME. In case if you want to install only core GNOME packages use :
# yum groupinstall ‘X Window System’ ‘GNOME’
