Unusual way for OS to start - text shown instead of Ubuntu image [duplicate]
Andrew Mclaughlin 
Since I've made small upgrades from upgrade manager, I started getting this unusual starting process (line of codes).
After that, my OS is fully loaded, but I want to make this as need.

This is not a unusual screen. The lines you see there are the details of boot process, and every line you see there has a meaning.
If you want your splash screen back (which you're here referring to Ubuntu Image), reinstall Plymouth.
What is Plymouth?
It's responsible for showing boot animations/splash on Ubuntu(Atleast stock).
EDIT : Before doing anything try hitting ESC or F1~F10 while you see this screen, it may take you back to the Plymouth Splash Screen.
