Necessary to create a new user account on my computer using 10.10.5. I am the only user. My Windows 10 was a Microsoft download upgrading from Windows 7. I reinstalled Parallels 10 but am having difficulty reinstalling Windows 10 for which I have no DVD. The Windows.pvm is in my Documents folder in the Parallels folder, but I'm obviously missing components to reinstall Windows. I'm at a loss to proceed. All the elements are in the other user account on my Mac. Is there an easy to way to do it that I'm obviously overlooking?
