Hello, When I start Parallels on my mac, it will do the beginning of loading of windows 7 (Ultimate). Then I get the feared Blue Death Screen with the error ' Unmountable Boot Volume' . I use the latest version of Parallels and all the updates from Windows are installed. No hardware has been added or removed. I did try to enlarge the amount of memory that could be used. I don't think I use Bootcamp (I never have to make a choice which OS I want to use...........) If I do a check disc from my Mac enviremont all is in order. Help is very much appreciated Rob
