    I cannot select the Upgrade option when I try to install Windows Vista, and receive the following message: “Windows cannot determine if another operating system exists on your computer”
    Please Help.

    What is the state of the system, is there another version of Windows installed? What version of Vista are you attempting to install? Most of the beta versions have upgrades disabled when you boot from the Vista DVD.

    Some little facts about installing Windows Vista.

    If you wipe your HDD completely then you do not have the option to upgrade this will be geyed out, therefore install on a fresh HDD.

    If you install over Windows XP without SP2 then Windows Vista will not install unless this service pack has been installed.

    Some version of Windows Vista have the upgrade disabled, which ones, to be honest I have tested every single one and cannot remember because I forgot to log them.

    Personally I don't agree with installing an OS over another one to upgrade to a new OS. It is commen sense to install Vista on a clean HDD freshly formatted.
