Right here's my situation. I have a MBP that has windows 7 installed via bootcamp for gaming and another windows 7 VM installed on Parallels for simple tasks. I want to know if there is any way to have only one version of W7 installed that will be able to run via bootcamp when i need all the resources for gaming but also be able to run as a VM in Parallels or VMWare when I just need to quickly run a program in windows? This way I can save some space on my HDD
