I have a different opinion here based on prior experience

When I used OpenSUSE regularly, it defaulted on using BTRFS and LVM2
irregardless of your partitioning scheme already in place. If you change
the partition table too much ahead or behind the Windows partition, Windows
will attempt to readd the HDD (and this happens more on 10 than it does any
other version) and will lose track of the UUID of the C drive/partition,
due to the design of its kernel. I've encountered this before, and you
either have to reinstall the OS or find some obscure Registry key and get
the new UUID of what it thinks the C drive is in order to set it correctly.
Debian 10 Buster sort of has this same scheme, set it up as LVM2 no matter
what the size. To be fair, Fedora does that, sets it to btrfs, *and*
encrypts your root partition by default and /home. I have no clue what
Ubuntu, RHEL, Void, Arch, Gentoo, or CentOS do though, haven't used those
in a long time.

I think it should be added because these kinds of situations are becoming
more common (and sometimes difficult to override). The last time I used
OpenSUSE Tumbleweed (2017-ish?), it gave me a very difficult time when I
tried to change it, even going as far as to ask me if I was sure 4 or 5
times. Most people (at least my age) would let it go at that point.

What needs to be changed exactly?
