I'm trying to install Win 11 on an M1 iMac. The installation keeps stopping and I get an error message saying "there is no VM installed." Technical Report #474496980. Thank you.
How are you installing Windows 11? The easiest way is to let Parallels download and install it. If you are using a Windows 11 install CD or iso file then likely it is not the version that will run on an ARM based CPU (like M1 Mac, Snapdragon PC, etc.) ARM based Windows 11 is not easy to obtain (Parallels has some deal with Microsoft to allow you to download it directly).
Microsoft has produced a 24H2 Windows 11 ARM ISO file which you can download directly from Microsoft.
After 10 minutes of wasted time, I just downloaded the MS ISO and used that. Simple, easy, and effective (and I have a real ISO I can reuse).
