Mac Forum / Applications / Virtual PC / October 2006

What are it's system requirements?  My guess is you're out of luck as
VPC is a dead product running on an emulated environment.  MS Virtual
Machine probably needs access to real PC hardware, not an emulated
environment.  Try running it on a real PC instead.

This is a data format conversion problem.  The VMware .vmdk disk format
is incompatible with VPC, all versions.  VMware has an import function
for VPC images but not vice-verse.

You can use a disk image transfer program like Norton Ghost or Acronis
TrueImage to transfer the data from the vmdk container to a Microsoft
VHD format, then that is a start.  Afterwards, you would probably have
to do a Windows repair installation, re-activate the Windows license due
to the virtual hardware changes, etal, then transfer it to the Mac, etc.

It can be done with a lot of patience and expertise.
