Burn it! Stop buying Microsoft products. That's the only answer.
Make sure the Game disc is not scratched
Read the game disc
If the dashboard says that there is no disc inserted. The disk drive is damaged and should be replaced.
There must be a scratch on the disc.
The Wii has a read only DVD , so you can't damage the game disc .
Typically that means the game disc cannot be read. Cleaning the disc may help the laser read it.
maybe your ps2 is mess up or something like that.
Read my answer under the question How do you play a PC game without the disc in the disc drive? on this site.
It's the game. Cleaning the disc usually fixes it.
send it to microsoft.
Well it should happen to more games but have you tried cleaning it? Or maybe you entered the disc the disc side the wrong way
Try wiping the disc with a towel or tissue to rub off any dust. There are probably scratches on it. If that doesn't work, your game may have too many scratches.
