I have a Windows 7 machine, running in parallels. I have to upgrade to Win 10.
I want to be able to have both versions of Windows running until I make sure that the Windows 10 install has all of the necessary data and programs migrated from Windows 7 to Windows 10.
Can I have both versions of Windows installed in parallels at the same time
How do I do that
How do I boot to each version of Windows
Please be as specific as possible
