Reminds me of the times when you could install Ubuntu via an .exe file using WUBI. This is how I started with Linux on my grandparents' computer without breaking it when I was 11.
Wow, you just threw me back to my childhood! WUBI was so cool. I haven't had the need for something similar in some time and Ventoy is my go-to tool for such things now.
A friend needed something like this two weeks ago and used WubiUEFI, a fork of WUBI, and it seemed to work with no issues.
