Fedora or UBuntu under VirtualPC?

I’d like to learn a bit about Linux.  I thought I’d install UBuntu or Fedora 9 under Virtual PC, but when I do, I get the following error message:

 

I can’t seem to find anything about it on Microsoft’s site.  Anybody have any suggestions?  I’ve got a Core 2 Duo E8200 @ 2.66ghz.  2 gig of RAM.  Virtual PC is running under Windows XP SP3.

I’d really like to get this working.  But when attempting to run either flavor of Linux, I get the above error.   If you have a thought, please leave me a comment.  Thanks!
