(I still haven't fixed my audio yet on Win10, but wanted to log this experience immediately in case I forget!) I will be updating this post since my journey isn't finished yet. I am not an expert and I'm not responsible for any errors that you may have if you are replicating any of my actions. Once again, this is just MY EXPERIENCE of how I was able to install windows 10 on my mid-2011 iMac. I am posting my experience here in case it does help anyone at all with research topics or tough issues that I was able to solve. (Also, I didn't see any community rules for post rules so I hope this is ok). If this post is inappropriate for this subreddit, I can remove it. I also might be using the Bootcamp drivers to fix the audio issue).
