I haven't used virtual machine technology before. My new notebook came with Windows 7 Professional 64-bit, and I prefer to run Windows XP and Windows 7 Professional 32-bit. I've installed the free VM Player on the notebook, and created a VHDX file containing Windows XP and Win 7 32-bit volumes from my old laptop. I created Windows XP and Windows 7 virtual machines with VM Player, and I'm given the choice of installing the operating systems with an .iso file or by inserting the installation CD. Can you provide instructions for using the VHDX file in VM Player?
