Hi All .

When I want to go into the ms dash the xbox says: oops, error 21.

Anyone knows what it is ?

21 - anywhere - This error says that the machine was booted to display a error, basically someone told the machine to reboot (or launch a xbe) with this flag, and the error code just means its been rebooted by the flag
