    Hi, there. I apologize if there's already a thread on this matter. I'
    really worried that I've lost all of my documents.

    Anyways, I bought a laptop with XP Home installed. I then downloade
    the beta 2 version of Vista, and had it install -over- XP. So, for
    while, Vista was the only operating system. Tonight, I decided t
    install XP Pro, so that I could dual-boot. Now, only XP Pro boots, an
    I can't get Vista to boot.

    The major problem is that I can't access my Vista user file
    (documents, etc.) from XP Pro. They're locked.

    The biggest problem is that I do not have a Vista DVD. I downloade
    beta 2 and then deleted the file after installing Vista.

    I know that I made a lot of bonehead moves, but I'm hoping tha
    somebody can help me out. How can I convince my laptop to boot Vista

    Would uninstalling XP restore my Vista boot? Or is the bootloader messe
    up completely

    Hey oddasudda--

    Two firm rules for the future.

    1) Upgrade installations that MSFT has provisioned for are acceptable. But
    what you did "over XP" is often a recipe for trouble and mangled files and
    is often called in slang a "dirty install." Don't do that again. This is
    what you did on one partition or drive installing Vista Beta 2 over XP. You
    were lucky to have a Vista that worked because often a dirty install won't.
    Then you decided to dual boot, but did it by installing Windows in reverse
    order. Oldest always should be first.

    2) The Rule with Windows if you are anticipating a dual or multiboot is to
    install the oldest OS first, preferably on its own parition or drive.

    You may get some help from these:

    Windows Vista no longer starts after you install an earlier version of the
    Windows operating system in a dual-boot configuration

    Installing previous versions of Windows on top of Windows Vista

    You cannot start Windows XP after you install Windows Vista in a dual-boot
    configuration together with Windows XP

    Also this may come in handy in sorting out boot loaders and may be easier to
    use than the BCDEDIT command, but you may be able to fix this with the first
    MSKB at the top.

    Good luck,

    No it wouldn't, and yes you can fix it:

    VistaBootPRO includes a copy of bootsect.exe which will fix your problem and
    don't even need to know how to use it. Just click on the Bootloader icon
    and pick
    reinstall the Vista boot loader.
