Does anyone know how to dual boot a chromebook with Linux?

[Aidan2018]

I have tried using crouton, Chrubuntu, chrx, and a Linux live drive and none have worked. I'm attempting to run it off of a external drive and have tried USB 3.0, USB 2.0, and an SD card. I have tried to download and run Ubuntu, Ubuntu Mate, Mint, and Galliumos. Any help would be appreciated.
