Thanks for both link on Dual boot Vista/XP and the Virtual PC suggestion.
I got a doubt. I'm definitely new to Vista, but that Virtual PC will be of help when Vista began to raise problems.
Have you had experience running Virtual PC on Vista Home Premium?
Is this Virtual PC Easy to install and easy to run? does it require special configurations settings?
After installing Virtual PC Sofware, we need to proceed to install WINXP?
What's the minimun requirement in term of equipment specs to be able to run Virtual PC on Vista?

As I'm new to this, your advise is welcome and appreciated!
