I tried that...but I don't like the fact you have to divvy up your hardware to use a VM. It's fine if you have and excess of CPU and RAM resources. If not it can be taxing on the host system. Right now with my dual boot setup of my Samsung RV511, I find myself staying on 8.1.1 Pro and rarely if ever I go back to 7. I don't have the lag a boot up you say you have.
