I no longer have the installation cd's from Microsoft. If buy a new installation disk for Windows 7 or buy Windows 10 what are the step creating a new VM or trying to reinstall on the VN that does not work so that I can keep the data apps I had on Windows 7? The attached file shows the error messages I get when trying to start the VM with Windows 7. Note that I used to be able to start Windows 7. Also from what I can tell the VM is looks for Windows on a SATA drive but I don't have a SATA drive on this machine if I understand correctly that a SATA drive is a solid-state drive. Note also that my other VM Windows Vista boots up fine.
