I have been using Windows 8.1 in Parallels 9 but now it will not boot into Windows as I'm getting the message above. It seems that Parallels is on my SATA drive when my boot drive is an SSD drive. Should I move the Applications (Parallels) folder from the HDD to the SSD? Is there a solution to this or will I have to reinstall Parallels and Windows? Thanks Christo
