I have tried searching the forum and am now more confused than before. I have upgraded to Snow Leopard on a new Seagate 500 GB (7200.4) using an external USB connector to the new Hard Drive, and will ultimately have it installed in my early 2008 15" MBP. I also run XP via a Fusion virtual machine, not Boot Camp. Migration Assistant moved everything over, including XP.vmwarevm (located in Users/MainMac/Documents/Virtual Machines). However, XP will not load. Thus do I need to use Winclone and SuperDuper even though I am not using Boot Camp? What files do I clone? Does a complete explanation exist in the forum? Can I later install XP via Boot Camp? Do I have to do a completely new installation, or can I somehow import the virtual machine? Finally, I am running Fusion 2.06. Do I need to upgrade to 3.0? v2.06 was supposedly updated to play nicely with SL.
