[Mojave Setup] I need to create a sub folder named via Terminal, but SSD with Mojave is Read Only

Hi all, quick question : I need to copy two files from USB to my SSD where I installed Mojave.

Problem is, with my two last commands required before I can finally boot; I am told that > /Volumes/Mojave/System/Library/Prelinkedkernels does not exist, when it should according to the guide I am following.

(It’s an AMD Ryzen Mojave Guide) Mojave is already Installed and this is just the final touches.

So assuming that no such directory exists, I went ahead and did this

cd /Volumes/Mojave/System/Library

And did that :

mkdir /Prelinkedkernels

To create the folder so I could then move the two files in there.

But, it says that it is read only. How can I modify this ? I just need these two files before finally booting up and this is the last problem !

Thank you all in advance !
