I've installed Windows 8 on Bootcamp and then I created a virtual machine from my Bootcamp partition with Parallels. I activated Windows under Bootcamp. Windows was perfectly activated under Parallels, but, when I used Bootcamp again, it thought I was using a different computer and told me I had to buy another license. That seems to be a frequent issue with Bootcamp/Parallels. Now, I've formatted the Bootcamp partition. I installed Windows 8 on it again, and I created another virtual machine in Parallels. However, I can't activate Windows 8 in neither Bootcamp or Parallels. I guess I'll have to activate it by phone. Which one should I do first? Can I activate it via phone to run on Bootcamp, and then activate it again via phone to run on Parallels? Or should I do it the other way round? Does Microsoft accept all these activations and re-activations via phone, one after another? Or should I just forget about Parallels now and use Bootcamp only? How should I proceed?
