I purchased a new Imac and I have a question about migrating from my Windows 7 machine( which came with Windows 7 pre-installed ) with Parallels 8. I think I understand that when installing Parallels 8 and you want to migrate you are supposed to insert a Windows 7 install disc. My Windows machine did not come with a disc, but I do have other copies of Windows 7 install discs for my laptop but not the machine I want to migrate from. Will using a generic Windows 7 install disc, allow me to migrate from the computer that came with Windows 7 pre-installed? Thanks.
