It would be better for your nerves to just do a normal GNU/Linux installation. There are too many ways the installation can go wrong:
replace swap partition with ISO contents
For example, Ubuntu ISO has a size of 5.7G. But my swap, which you previously deactivated, was 4G. Either 2G, or it didn't exist at all.
move user data from C:/ to other partition
The other partition may not exist or may have capacity smaller than C:/.
replace C:/ with linux
The installed Linux must also be stored somewhere. And there is also a copy partition for C. The same problem of lack of space.
move user data to /home/$username
From %APPDATA%? You would have to be a know-it-all to resolve the location paths and configuration names of literally every existing program.
reboot into linux
~~And it is at this moment that Windows will completely randomly decide to update and rewrite the bootloader :)~~
When I started learning programming, I was like "tf is a map function?" and I always forgot about it. Then I tried the functional programming language Erlang and understood all these functions very well. But there is a downside, now most for-loops in C++ look terrible to me :)
