A little help

Okay, I'm sure this has happend before and I'm hoping it can be fixed, I used the hotswap method on my xbox and I followed a tutorial exactly, anyways all went well and after the linux disc said "All done!" I waited the five seconds, shut off my xbox and pc but whenever i turn on my xbox i have no dash, not even the original xbox dash, i can still play games (tested halo 2) and save, but i dont understand the problem, any solution would be appreciated, thanks a bunch.
