I posted the following problem in response to the above referenced article in trying to load Parallels and Windows 10 on my new Macbook Pro with the M1 chip.
"Hello, this is a great article but when I get to the Installation Assistant, I get the message "Unable to Detect Operating System." I have tried what I have read in other forums (e.g., making sure both files are in the same folder, etc.) but nothing seems to work. I am going to have to return my new Macbook Pro (M1) soon if I can't get this figured out. Any suggestions? Thanks!"
EddieL responded that "This is not a supported scenario" and then closed the thread.
If I could reply to the thread, I would have the question that the article clearly states that if you sign up for the Insider Program (which I did), you could run the program. It states: As for Windows 10, support right now is unofficial, but users can actually get it running using a VHDX image provided through the Windows Insider Preview program." I was given an activation key. If I followed all these steps, why would EddieL of Microsoft Support say it was not a supported scenario?
