you need to press X to delete the plugin path, the move with rb to the page where you load/save configs highlight hdd and press Y to delete config and then X to save new one.
Hello, i had the same problem as you and it's the plugin, the aurora crash patcher. disable it to play xbox original games. I had to delete the config file in dashlauch. I figured it out yesterday.
Like jeannotte says, copy all the files from SD to the HDD, also verify is formated in fat32, cluster size of 32kb, partition active and primary (the last 2 can be verified with minitool partition wizard), and MBR, i forgot that.
