Cannot boot back into Chrome OS

[superuser-does]

I was able to install it on UFS on my Acer Chromebook Plus 515 (OMNIGUL board), but I can no longer boot into Chrome OS. Booting into Fedora 41 does work, but all other options lead to a black screen.

Though I also found that it's reported inconsistently; cbmem believes it's NVMe, while dmesg correctly identifies it as UFS.

I followed the ISO image guide on the Ultramarine Linux website*. The only difference is that I gave the partition slightly more than 16 MiB - just in case. I do not believe this matters, but please let me know if it does.

* Specific version of ISO image guide

Very similar case here - the only difference being I have Accer 514. I wonder if anyone managed to actually go back to booting ChromeOS if Submarine is on internal drive?

Booting ChromeOS from submarine is unlikely to work since the ChromeOS kernel iirc is heavily modified and/or relies on being booted by depthcharge directly.

There is no way to boot chromeos from submarine at all. u-root does not understand how to boot a depthcharge boot image.
