Novas can pretty much go back to a normal-looking, if evolved, star.
Supernovas do leave quite a bit of material behind, typically 0.3 to 3 solar masses of material from a star that was originally 5 to 20 solar masses. If it's well under 1.4 solar masses left behind, it becomes a neutron star; if it's well over, it becomes a black hole; intermediate cases can go one way or the other, depending on the symmetry of the explosion.

The first thing,the original ejecta,eventually crashes into the
hydrogen field that produced the massive star.
Many solar systems like ours are the result.
A 2 or 3 solar mass remnant is left called a white dwarf.
The white dwarf evolves from there,but I guess this is going beyond the question.

Most of it gets blasted out into space. Some material will remain. Depending on how much, it could become a white dwarf, a neutron star or a black hole.

I think it makes a black hole.
