xbox 21 error

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

This occurs frequently when the xbox is unable to boot due to dashboard changes being made (ie Gcue true blue hasnt been resigned, parts of the stock dash are missing - incomplete FTP backups copied to a new HDD for example).

Service Error 21

Info: 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. This error seems to show up more often when hacking/patching/customizing the original dashboard. E21 (Error 21) is a dashboard related error.

Normally it means you are missing vital files from your xbox c:\ parition or you are running the wrong M$ Dashboard for your xbox version.

E20 is directly related to the Dashboard files but i have found from previous experience E21 is very simlar. Even though you get E21 you should still be able to BOOT GAMES from the DVDROM drive.. The bios boots the DVDROM first and if no dvd found in the drive it will boot the xbox c:\ parition next.

Solution: You probably are running the wrong dashboard for your xbox version. Use the 'HQ Auto Installer Deluxe' to reinstall your Retail M$ Dashboard.. It should fix this error no matter which xbox version you have.. If not try downloading another Retail M$ Dashboard.
