As the title implies, I decided to uninstall Dios Mios after being unable to boot from HDD. My problem is that I can no longer boot retail discs. I understand that DM messed with a file needed to boot my retail copies. What do I need to reinstall to get them working again? Any help that can be offered is appreciated. Edit: So, admittedly, I posted in a panic without thinking. Dios Mios (as the name implies) overwrites your Mios. This is used to run GC games. Just download the MIOS through NUS or Modmii and use MMM to install it. The lesson to be learned here is not to blindly rush into modding like I did. Know what you're doing before you do it.
