I think you did. From July 2024:
I cannot for the life of me find info on how to change the kernel order on boot, so I don’t have to always scroll down to the list to pick the most recent Kernel, and end up in the LTS kernel if I miss it, because I have it as a “just in case” choice.
You got this reply:
Then you said:
Hey thanks! Of course I didn’t look for the “How to…” in installation instructions, and I looked for the answer here! Every once in a while you can search high and low with all kinds of ways of asking, only to find nothing, and then you find the answer in a posting with a completely irrelevant title! You would think “systemd, change boot menu” would be a sure hit!
I think it is safe to make the assumption that you used the information in that link to change the kernel boot order to default to the current kernel. When you made your new “clean install” you forgot that you had done this.
