can't display armbian's interface screen

[NewBie2002]

Dear guys, 

Recently i am trying to install Armbian on orange pi pc plus using Mobaxterm but for some reason after finishing the installation it shows only Armbian-config screen but not the GUI interface.
I don't know if I installed it right or wrong. Hope everyone can help me because this is a subject project of mine in university.

Thanks so much.

If you mean by installation moving the OS to onboard memory (eMMC) then first write image to and SD card (check docs if necessary) and then use armbian-install (or nand-sata-install on older images) to move OS to eMMC.
