Yes, in the old thread i tested an older garuda install i had left over on an external drive, if it counts.
I sadly dont know much about boot parameters, how they work, or where to find them, same for modules… Think I will have to test again, if a current garuda may work, or just a old garuda works… if it doesnt, maybe something else at some point…
That was when I didnt use any of these tools, so might have been hybrid and using intel as it wasnt under load.. what would also explain that i get the excact same errors when using hybrid with envy-control, and different errors when using integrated only, or nvidia?
will try one after the other, even if im not shure if it will make a difference… And yes, the endeavour wiki is very much better to understand, which i used a couple years back to install envy-control where i was even more nooby then i am now. which is also, why endeavour is best 
I tried it already with 575xx and 550xx (not with envycontrol, or prime or similar).. Should I try again with 580xx and see what happens if i use one of these tools?
Also for the note, I will do these things not now, but when i feel better. i currently have very bad migraine, and looking at screens makes it even more painful to a point where i get dizzy and feel sick.. i have this since yesterday evening but i wanted to take time now to reply to all of you because you want to help me and im super thankful to all of you, but i will probably take a day or 2 to feel better to get back to try to fix my laptop
