I believe the following to be correct, and would be most grateful if someone could confirm. If one wants to 'dual boot', the user must have a legal license for each of the operating systems. If one purchases an Update version of Win7, the OS being updated can not be kept as a 'dual boot'. Also if you want to run an additional separate OS in a Virtual Space, an extra license is required.

All true.Carey Frisch

Thank you.....
