3.1 OS and Kodi Installation
Kodi can be installed on the ChromeBox in a variety of ways. The two most common are via OpenELEC or Ubuntu+Kodi, in either a standalone or dual boot configuration. This is accomplished via the ChromeBox E-Z Setup script, which must be run (at least initially) from ChromeOS.

I was told that I made it install Krypton. I used the following info, It never mentions krypton. How do I fix it to install Jarvis.

The EZ setup script will facilitate everything needed to install either a dual boot setup, or install a custom firmware which allows the installation of any Linux-based OS in standalone mode.

To run the ChromeBox E-Z Setup script, perform the following steps:
Power on and boot to ChromeOS. Do not log in, but ensure a network connection is established.
Hit [CTRL][ALT][F2] to open a command prompt ([CTRL][ALT][<--] for ChromeOS keyboards)
Login with user chronos (no password required)
Download and run the ChromeBox setup script using the following two commands (hit enter after typing each command):
curl -L -O http://mrchromebox.tech/setup-kodi.sh
sudo bash setup-kodi.sh

I don't see any mention of either Jarvis or Krypton -- what's your question exactly? When you run the script and select one of the LibreELEC install options, you're prompted which version you'd like to install - with the default being the current stable version
