@YasuyukiM2 Your English is fine and that post really helped me solving my problem with installing Win10 @CarlosR29 Thank you so much for your image - is working perfect!!! Now i am Running Win10 and Win11 - both from this ISO file because Microsoft offers inplace upgrade to newer Release. So when you want to stay in Windows 10 you must decline the updates and disable Windows Update Service. This was my first post in Parallels Forum and i am deeply impressed by the members!! Thank you for your help!
