I just installed Ubuntu 15.10 on VM and I can't change desktop environment. In previous versions you could switch between Unity and Gnome on login screen, but now this option have gone.
Or am I doing something wrong?

That's because you haven't installed it yet :)
Open a terminal with Ctrl+Alt+T and enter:
sudo apt-get install ubuntu-gnome-desktop
If you have multiple DE's installed, you will see it.
Try Kubuntu :
sudo apt-get install kubuntu-desktop
or lxde :
sudo apt-get install lubuntu-desktop
Or gnome :
sudo apt-get install gnome
Please note, it downloads quite a few packages.
Do you even have GNOME installed? Open a terminal and run
sudo apt-get install gnome-shell
After it's installed you should be able to login with GNOME.
