Ive followed the guide for dual booting up until installing an os, which im stuck on. I have no flash drives in my house so i used an sd card, downloaded the arch linux installer, and used the chromeos recovery tool to turn the sd card into a bootable device since it will take any file, not just chrome os apparently, and now ive been sitting on my bed trying every possible way to maybe get it to work. My chromebook has an sd card reader in it, so ive always just used that. My board is magma-qzpr c3b-j3c-e4e-j4b-q84
Turns out my sister had some flash drives lying around in her room, i dont need any help anymore
