Running a distro in a disk image has always been my favourite install method since wubi came out because a backup was only a question of copying a disk image and a couple of grub config files.
Then brunch applied the same method for ChromeOS but not only for windows, you could do it on Linux too.
Now with Linuxloops all setup has been automated and extended to many other distributions, not only ChromeOS.
Ventoy
Ventoy is good, but this utility serves a completely different purpose.
Can you explain what role linuxloops fulfils?
In case of a disk image, to test or use a different distro (or a distro inside windows) without repartitioning the drive.
Check “Installing windows in a disk image”, that’s genial. https://github.com/sebanc/linuxloops/blob/main/Readme/Recommended-setups.md
