Strange Behaviour of Vim on New Lines

I have the problem with DOS new lines (0d 0a), which I try to replace in vim. I believe to make already couple of times before, but now I am really stuck, as vim does not want to see the character:

  1. When I try to enter it by pressing CTRL V and CTRL M to run :%s/^M//g, I see the error:

    E486: Pattern not found: ^M

  2. Even when I try to replace it by hex code with :%s/\%x0d//g, I see the error:

    E486: Pattern not found: \%x0d

    I, however, can remove/replace other characters, e.g. :%s/\%x61//g

  3. When I try :%s/\n/\r/g, nothing happens

  4. When I try to remove it in two steps with :%s/\n/XXX/g followed by :%s/XXX//g, it goes away. However, in case I use :%s/XXX/\r/g on the second step, vim inserts 0d 0a back instead of expected 0a

Therefore, question: is there a way to convert all new lines to 0a in vim? Why does hex replacement not work?

See :help 'fileformat'.

:set ff=unix
:w

should do it.

This is matching newlines, by the way:

:%s/\n/\r/

But it's replacing newlines with newlines, and when you write the buffer vim will use whatever line ending is determined by 'fileformat'.
