I had a softmodded xbox and swapped out the hard drive for a larger one successfully. I was able to ftp and watch movies on it. I was chaning the themes and ended up on the xbox 360 theme and then reset the xbox using the controller and it went black so I hard reset the xbox and now it loads the xbox screen at the start up but wont go any further. It will play xbox games from a disk as well. Any ideas what I have done. is it corrupt and do I need to reformat the HD and do everything over again? Help appreciated.
