I am trying to install endeavourOS with submarine on my Chromebook (redrix). But after I choose EOS in boot menu, the screen goes black and I can’t do anything. I don’t know what happen and how to get logs to debug.
never heard of submarine did a search but could only find actual Submarine’s.
Welcome to the forum 
Not sure if this Guide would be of some help.

I am sorry for my oversight. Here is the repo of submarine.
I saw this issue in telegram, did a big of search and found that this particular chromebook is x86_64.
I haven’t dealt with chromebooks so far, but here the issue appears to be bootloader.
It would be great if @lostdeers can inform us on how they burn the image onto their usb

Yes, HP elite dragonfly chromebook(redrix) is x86_64. I use dd command to write the whole iso image to the usb storage, that works good. And I boot with submarine at another usb.
further more I can edit the kernel params in submarine boot shell if there are some extra params needed
Can you try the ISO burning methods in this article, so that we eliminate the method issue?

Also are you able to get to any TTY? (ctrl+alt+f3/f4 etc.). If you are, the logs would help:

I also found this guide, with a websearch: https://developer.fyralabs.com/submarine/guide_arch
Most of the method in the guide will work with with some adjustments if you able to boot the ISO
Sorry for my late reply. In these days I have tried to install Archlinux manually with official archiso. It works well. But there is a problem makes me mad so I change my chromebook to Fedora. That’s a problem with Intel Xe Graphics. GuC and HuC cannot initialize when booting which make my WM (niri/hyprland) can not work and I can’t even find same issue on the Internet.
I read the articles you show. I notice that Secureboot may be the key issues.
And unfortunately, my chromebook does not have F* keys which are replaced by some functions key like back mute…(ChromeOS does not need F* keys)
Thanks for your help and I will keep discovering and find a way to run .
This submarine is quite obscrue and misterious for me. I met the same problem when installing EndeavourOS on redrix. I also found that the modern standby (S0 sleep) worked perfectly when using Ultramarine (based on Fedora) with Gnome, but NOT for the KDE version! I’m wondering if there is any way to make it possible for general linux distros.
Also submitting an issue to the github repo might be a better way to find the solution.
Someone says it blames to some widgets of KDE, I use niri, s0ix and hibernate works well.
