Virtual PC 2007 SP1 crashes when trying to install ubuntu 8.1. I hit F4 and then select “Safe Graphics Mode”. Then hit F6, and you’ll see the command line for the install. I delete the "quiet splash" and add vga=791 noreplace-paravirt at the end, press enter and the installation begins and vpc crashes soon after that I also tried using "vesa vga" at the install command line but that does not work either. BTW I'm installing ubuntu from a virtual disc but that should not be a problem.
