I got minecraft at GameStop today. I put it into my Xbox one and nothing happened so I tried to eject the disk but nothing happened

Alright, this doesn't answer your question, but I also got Minecraft for Xbox One today lol.

Whatever you do, be careful. Malfunctioning electronics can be very dangerous. If you're feeling comfortable, unplug the console and use a flat ended screwdriver to try and manually eject the disk.
