BlackArch is not installed correctly, what should I do?

Question

Arch Linux

Hello.
I install BlackArch on a virtual machine using Netinstall. I also tried Live ISO. Did everything right, checked from off source. But after a reboot, no GUI appears. Just an empty console BlackArch without any scripts. Nothing has been installed at all. How to install what would be with the scripts and with the GUI? I'm talking about Windows Managers.
Write in the comments for details, I do not know what to add.
