What effect will installing Ventura have on bootcamp windows

Bootcamp is not supported on Apple Silicon Macs. I don't have Ventura installed on an Intel Mac, and if it is there in Ventura, you may need a Windows upgrade (e.g. 10) to be supported there. If Boot Camp is present, launch it, and click on its open boot camp assistant help button to get more information. I do not believe that Boot Camp supports the Intel version of Windows 11 yet.
