Windows 7: Windows VPC, Uninstall unactivated XP, Acronis copy

Ok, I just remembered VPC only gives me about 130 GB of space, and my question involves a larger backup.

However, I installed Windows VPC to my Win 7 Home Premium laptop. I can't get the free copy of Win XP activated, so within 30 days I have to get that uninstalled. How do I uninstall my unactivated copy of XP from Win VPC?



I also have an Acronis backup from my semi-defunct XP machine and wouldn't mind putting some of that on Win VPC. Is there a way to do that? Like over-install on top of my unactivated Win XP? Yeah, yeah, it might not like my Dell code for XP.

My last choice is to break out a retail copy of Win XP from my closet and hope Win 8 can support Win VPC on a second HDD & support Win XP in Win VPC. I really need a lot more than 130 GB, that's so 2001!
