High energy neutrino emission from gamma-ray bursts (GRBs) has been expected in various scenarios. In this paper, we study neutrino emission under the various models for early afterglows of GRBs, and discuss implications for neutrino signals from recent Swift observations. Future neutrino detectors such as IceCube might detect neutrino signals from early afterglows under the late prompt emission model, but it would be difficult under the reverse-forward shock model. Neutrino-detections are inviting because they could provide us with not only information on baryon acceleration but also one of the clues to the model of early afterglows. They also lead to motivating neutrino telescopes that are larger than IceCube. Finally, we compare various predictions for the neutrino background from GRBs.
