I have a dual boot XP & Vista and have successfully split them. Both OS's both if I boot to the DD CD and mark one as active. I hide the other OS and have a shared data drive. All works fine. However, when I try to activate OSS it doesn't recognize Vista and it leaves me with only XP. I then have to go back to DD and set vista as active to get back into vista. Attached is my bootwiz file and disk setup screenshots. I'm guessing I need to manually edit the bootwiz.oss file with the vista parameters but not sure how to do it. Please help!
