How to delete AppleIntelSNBGraphicsFB.kext folder? I can't!

[Javier Oyanader 0]

I need your great help. I haven't been able to start the installation of Olarila El Capitan for a week, researching on the internet I found that the solution was to delete the AppleIntelSNBGraphicsFB.kext folder since the graphics of the laptop I have are of the first generation.
but i can't delete the folder!

try everything possible but it won't let me as it jumps alert that the system is read-only.
I already tried root from linux and couldn't either.

How can I delete this folder?  

 

 

the specifications of the lapton i want to install the mac os is

 

Processor: Intel Core i3-330 Screen size: 39.4 cm (15.5 ") Storage: 500 GB RAM: 4GB Installed

 

THANKS!
