I am currently running Windows 7 Enterprise.

I want to be able to run Windows XP and have tried things like VirtualBox and Windows Virtual PC... Those haven't worked. I want to play a few old games and they just won't respond when I use WVP and VirtualBox.

So, I shrunk my main hard disk volume to create and format a new 5gb disk and tried to follow the instructions here http://windows.microsoft.com/en-US/w...stem-multiboot to install XP using a CD. However, when I insert the disk I get this screen: http://tinypic.com/r/205xnag/5

Obviously I can't start to follow the instructions from Microsoft if it won't even let me install the OS. What do I do from here?

Also, once I do get it installed (if ever) how do I choose which disk (XP or 7) to make my computer boot from?
