Q: I have a problem with my old macintosh lc ii

I have an old macintosh LC II that I bought from a garage sale and whenever I try to use it, it turns on then shows and icon of a floppy disk with a question mark. I think I have downloaded the right thing to my floppy disk, but the person who told me before said I also have to format it somehow. Is there anyway I can do that on a windows computer?
