I ran Win8 Pro on Bootcamp on my mid 2012 rMPB with VMWare Fusion VM based on the bootcamp partition. Win8 was activated on both bootcamp and under VMWare but I do remember having to do a phone activation. I successfully upgraded and activated Win10 Pro under Bootcamp 7 days ago, but new VM won't activate. Reading VMWARE and Parallels forums, this might be a systemic problem. Some posters have suggested it just takes time but I'm still waiting. Has anyone gotten both a bootcamp and VM Win10 activated on both? If so, please explain how you got it done!
