Im at work now, today i updated StarDust and AMS to 14.1.1 and i dont know why but ubuntu appeared on StarDust Menu, i didnt tested it to boot it, when im home i will test it, but i didnt installed it, cause of missing L4T Partition, im curious what happens when i try to boot it instead.It won't show up in blue in Hekate. It will be part of the Orange (unformatted.) If you don't have a blank partition then L4T won't install. In other words the image files need a place to go and they will NOT overwrite your Android partitions. If the "Image L4T" button is enabled and pressable...it means you have the image files in the right place and an appropriate blank partition of the right size available, so go ahead and press it.
just remembered…the pics I shared earlier had all 4 partitions defined.
1) my partitions being set up

2) what those partitions looked like after it was done formatting.

3) What those partitions (with no blue in the second pic) looked like to another tool. See disk 5 with 2 x 8G partitions.

I believe you’re all set to give it a go.
