I don't need it actually because I can dual boot into Ubuntu from my PC here. I just want to give it a try, you don't have too many free products like this from Microsoft.
I haven't tried but I can assume that it'll be a piece of cake if you want to install another Microsoft's OS in VPC. I tried installing Ubuntu 8.04. It certainly wasn't easy and I found a good article telling me exactly what to do.
Don't rush like me, following the article didn't take me anywhere. There are 160+ comments the real wisdom is in those comments posted by readers. Key steps you shouldn't miss are
- Don't install straight into HDD, run live CD then install
- Use graphic safe mode (F4) and add additional commands to startup script (F6)
- Edit grub script during first boot
Enough for VPC, I prefer Wubi
