Hi@akhtar,

For new installation of CentOS/RHEL, 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. If the server is installed without GUI, please follow the steps below to install the required RPM packages.

  •  Install GUI packages.

$ yum groupinstall 'X Window System' 'GNOME' -y
  •  After installation complete, you can boot into GUI without rebooting with the below command.

$ systemctl isolate graphical.target
  • Modify the target as graphical.target to bring the system in to the GUI mode by default.

$ systemctl enable graphical.target --force
  • Verify the current target.

$ systemctl get-default

Hope this will help you.
