I have a major issue and can't open windows 10. Using v 15 and Mojave. I get a critical process error and can't start windows 10 in safe mode, restart, wipe , nothing. Is it possible to access the windows C drive from the Mac side? If so, where?
Could you please provide us with the screenshot of the critical error which you had? Also you can mount your virtual hard drive to your mac and access your Windows files, please check this article for more info.
Thank a lot for the provided info. Could you please collect the tech.report after the issue reproduced and post the report's ID here?
