A linux installer for windows that works just like a normal installer on windows. You download the .exe, double click it, it opens a wizard you can walk though, and by the end of the process, after it reboots, you're in a linux distro.
How could something like this be implemented?
My idea:
Best case scenario where multiple data partitions exist and can accommodate the user data stored on C:/ + there's a swap partition -->
download a linux iso
deactivate swap
replace swap partition with ISO contents
modify contents to auto install linux with settings from wizard
add boot entry to boot from old swap / modified ISO
reboot
install linux with a nice progress animation
move user data from C:/ to other partition
replace C:/ with linux
install alternatives to programs found on windows (firefox for edge, gimp for paint, inkscape for ..., libreoffice for MS office, etc.)
move user data to /home/$username
configure DE with theme (gnome for macos look, kde with theme for windows look)
other customisations
reboot into linux
Dunno if this is feasible in the best case scenario.
