What are the awful performance issues?

If you're running linux already, you want to use virtualbox. otherwise its a big hassle if you just want windows on your computer.

Depending what you want to do with this machine, you may better installing linux. it will run much better on this laptop.

I would recommend debian linux with xfce4 desktop environment, but original poster is asking which way to install windows so he propably wants to install windows

What a great song

I see, in the fear of death one might get rid of the money

Where goes the money wtf? Why would anyone support this?
