Blackout after XP boots I also have the same sympotom as this. With 1970, XP w/SP2 successfully boots past the XP splash screen, but with 3106, the screen blacks out after the splash. I did not check the error message, but uninstalling 3106 and getting back to 1970 will make my XP VM boot without any problem. I tried reinstalling 3106 a couple of times, but the result was the same. I suspect this has something to do with Parallels Tools, especially the version mismatch might be causing this blackout, but I am not sure. Does anybody have this symptom too?
