Noob to Linux here and I need some help. I’m trying to figure out how to change/customize my splash screen and don’t exactly know what process to go through to do exactly that. I’d love the help! 
Can you take a picture of the screen you are referring to and post it here please? A phone picture will do.
Sure. That is called the Plymouth boot theme.
This Q&A will help you.
Awesome! Thank you very much!
