You don't say what Roku model and model number you have. It's always a good idea to give this information as sometimes it makes a difference. Find out via Settings > System > About.
If your model is one that supports an SD memory card, a corrupted memory card has been known to prevent the startup from completing. If you have one in place, try removing the card and see if this allows the startup to complete.
