For those who have Intel-based Macs...

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

.... I want to treat you all with an insight to what is possible (because I
have this configuration running right now as I write this) if you want to
install Windows on the Mac via Boot Camp, but want to preserve your former
Virtual PC installation within the new Windows environment on our Mac.

This was exactly my scenario: I have Windows Vista Business that I want to
run under Boot Camp on my MacBook Pro, but I have stuff I want to migrate
from Windows XP running under a virtual machine on an old PowerPC-based Mac
(my PowerBook G4, incidentally) running Virtual PC.

And according to the EULA that comes with Virtual PC, I actually am entitled
to do this legally under the new arrangement because the copy of Windows
that ran under the old Virtual PC installation will continue to run in the
same way under the new installation... so you can forget worrying about any
legalities when you do this, except for two issues:

* you promise to forfeit your Virtual PC installation on the PowerPC-based
Mac, and the installation of Windows within, and
* you may have to re-authenticate Windows when you migrate your installation
on your new Intel-based Mac.

[Important: for the above to be true, you must have a Virtual PC product
with a version of Windows that you actually intend to use on the upgraded
system, or you need a retail product of Windows, which comes with its own
EULA and installation disks. Using a product that did not come with your
licensed copy of Virtual PC or Windows retail is a voilation of the Windows
and/or Virtual PC and/or Office v.Mac Professional EULA.]

If Windows came with your Virtual PC:Mac or Office v.Mac Professional
product, then you will have no problems running under the new environment,
either technically or legally.

So what is the new environment that I am so excited about? Well, I simply
came to the realisation that even though I can boot Windows on my Mac via
Boot Camp, I can also augment this environment with an installation of
Virtual PC 2007 SP1 for Windows, of which can be obtained for free from:

http://www.microsoft.com/windows/products/winfamily/virtualpc/default.mspx

to run older installations of Windows on my Intel-based Macintosh! So now I
have a way to run the former virtual machine on a faster environment, in a
completely compatible manner that does not involve translating virtual
machines from one product to another.

The slightly tricky part is copying the hard disk image(s) to the Windows
Vista boot partition. This mailout shows how to prepare your disk images so
that Virtual PC 2007 can boot them.

Firstly, you need an Intel-based Mac with Leopard installed (or Tiger, if
you have dared to keep a beta of Boot Camp running on your system!), and you
need to install a host Windows installation. I have used Windows Vista
Business on my setup-but you can also use Windows XP SP2, since you need to
have a supported version of Windows available for Boot Camp to boot into.

After you have Vista or XP installed on the Boot Camp partition, download
Virtual PC 2007 and install that into your Windows environment. After you
have that up and running, don't prepare a virtual machine for it just yet...
you'll want to get your old virtual machine into the Windows system first.

To do that, you can:

* prepare the host Windows XP or Vista system to enable file sharing, so
that your PowerPC-based Mac can mount its SMB file share.

* copy your virtual machine <name>.vpc7 to the host Windows installation on
your Intel-based Mac via SMB networking.

There are other ways you could copy the virtual machine over... but I chose
what I think is the quickest and cheapest solution.

Then, in Virtual PC 2007, make a new virtual machine. You need to do this
because Virtual PC for Mac and Virtual PC 2007 have different filing
conventions for representing your virtual machine-dropping in the Mac's
virtual machine for Virtual PC 2007 to pick up will not work, because
Virtual PC 2007 cannot identify Virtual PC's virtual machines.
