@kn1ghtone I am a little confused by your post.
I just removed power and Rasbian always boots.
You mean you just pull the cord? Not recommended.
Then you say
retropie will not start after i do a shutdown from the menu. I can reboot it just fine. I can copy files to it. I can run games from it. As soon as I shut it down, it will not turn back on.
What do you mean by this? "Will not start?" followed by "I can boot just fine?" - What are you trying to do? Describe exactly. Once you shut down from the menu correctly, you have to disconnect the power. I use a switch for this purpose. Then, when you reconnect the power, it will boot. I am confused by your "I can boot just fine" comment.
