It is not a squat from the floor. Take a video, and watch when the bar breaks from the floor. Do your hips rise up before the bar breaks the floor? If so, you need to set your ass higher from the start. Also, make sure that your scapula are directly above the bar, not your shoulder socket. If you don't, you're just going to end up with the bar moving back to that position anyway.
The legs act as an anchor for your glutes and lower back to do the pulling. You should feel it in your hamstrings, but it's mostly a really hard isometric contraction that is going on there.
If your back is in proper extension (not rounded), then even if it seems as though all the pulling is coming from your back, that's okay. The spine is protected from your lower back muscles contracting and keeping the lumbar spine extended.
here's a good writeup:
