Since the film is intentionally ruined now, I'll use its spool as the starting spool (you only need one empty spool in your lifetime for starting MF photography)
No empty spool in your camera ? There should be one left behind in it.
Any way what kind of camera is it ? Do you have a manual for it ? Try and google the camera name and see if you can find any info on it. I have seen some site showing how to load different cameras so you should be able to find something.
BTW that was a great tip Blansky came up with.
