Do you have a bootable dash like Slayer's or AutoInstaller Deluxe? If so you can boot off of those and make sure you are loading the correct dash.

i booted off the mech assult glitch to get run linux but i didnt change the dash at all i still have the stock ms dash but now i dont have ne dash so i need something to reverse it and get a new dash

So its a messed up softmod this thread may help http://forums.xbox-scene.com/index.php?showtopic=442663 I think you can recover your MS Dash and then re-do your mod.
