Upgrade from 7 virtual machine to fresh non virtual boot? HELP

Okay, so I snagged a cheapo copy of Windows 7 off amazon so I could get a legit copy of 10 on my Mac Boot Camp on the cheap. Didnt realize however that Boot Camp only supports 8+ ... so I'm going to try and install 7 in a VM, then upgrade to 10, find serial somehow, then do a fresh install of 10 with bootcamp .. somehow.

Any ideas guys?
