Q:

How do I remove Kubuntu loading screen? 

I want to have the normal boot instructions and not the loading Kubuntu screen. 
How do I remove it? 

A:

You can edit /etc/default/grub and find the line that looks like
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

and remove the quiet splash parameters, which may leave the line looking like
GRUB_CMDLINE_LINUX_DEFAULT=""

After editing, run sudo update-grub
and you should boot without the Kubuntu loading screen
