I'm new to this, but you would be best using a virtual machine of some kind (I was just about to post a thread about them!) - it's an application that runs in whatever operating system you are running, and you install other operating systems onto it.
I've used Virtual PC inside XP Pro, to run other XP Pro's and also Server 2003 - it works fine. It's slow, but I think that's because of the hardware - it's only built to run one OS at a time.
Again, I'm no expert on Virtual PC, so I don't know if it can be made to run fullscreen at a decent resolution; it probably can.
This thread is really cool!, http://forums.overclockers.co.uk/sho...php?t=17837433
- I was just reading it and it reminded me to ask here who uses what virtual machine app's and what they recommend.
