Hello,

When I purchased my computer, they installed both Vista and XP as a dual-boot system. I never really went into Vista since I was using programs that only operated on XP but now I'm getting a message that my XP is not genuine and the only product key I have is for Vista. I can't find my original Vista CD and it now occurs to me that they probably installed Vista as a genuine version and then just added a copy of XP. This not-genuine version is affecting the functionality of my computer but the dual boot option no longer shows up! I have backed up my personal files. Is there a way to wipe the system and install the genuine Vista that i paid for without the CD, but having the sticker on the computer with the Vista product key? Thanks for any help you can provide!Configuration: Windows XP
