Problem solved, although I'm not sure how I did it. But on one of my attempts to open W7 in the opening black box there was a message that said something like "insert the W7 CD/DVD and press enter". I did this and the installation process resumed. Eventually I was again asked for the Product Key and accepted the same one I had previously entered. So I guess no damage was done when the installation was interrupted. It took a while but W7 works fine under Parallels 6. NOTE: I did try to open XP while W7 was running and it took forever, maybe ten minutes to open. I think that is because I only have 1 gig of RAM allocated to Parallels and both XP and W7 require lots of RAM.
