wubi? I remember using it ~2011.

I wanna say it was a little different? Super idiot-proofed for a windows user. Download a .exe from the ubuntu website, might've downloaded something after installation I don't remember, then click a few buttons and wait.

I remember using this as well for my first foray into linux. Don't remember any details, beyond what you said though.

Ubuntu provided a Windows installer to set it up, but it was indeed wubi under the hood.
