Good.

Sounds good.

I've answered much of this before in the previous thread.

My suggestions:
• follow the blog post I linked to -- remove absolutely everything
from Windows, shrink it as small as it will go, but leave it there for
future firmware updates and so on.
• Install a clean copy of 20.04 so as to get the Ubuntu entries in the ESP
• Then try replacing the fresh copy with a copy of your old one

There's lots of guidance online on this and I'm no expert in UEFI stuff.

That's what I'd do but dual-boot between a minimal copy of Windows and
a new clean Ubuintu.

Precisely.
