I am running a Mac Power Book and have win XP installed in a separate partition using Boot Camp.
i purchase VMWare Fussion so I could run Win XP in a Virtual Machine and not have to reboot to use XP. For some reeason VMware tells me that the WIN XP closed improperly and has to be rebooted to clear the disk errors. i downloaded a trial copy of Parallels and it is able to run the Boot camp XP in a virtual machine with no problems.
The Tech support from VMware is abismal and have not been able to get an answer from any of the other forums I have posted on Other than some KB articles saying something about revalidation of Windows.
