    Installing XP on a second hard drive has clobbered Vista on the primary

    I do not have my Vista DVD with me and am wondering the easiest way to
    recover Vista ?

    I obviously have a XP CD with me, and am hoping that I can get away with out
    having to redownload a Vista ISO from MSDN Subscriptions.

    Any help welcomed,

  2. You always install the oldest OS first to the newest.
    The recovery process will require your Vista DVD to replace you now
    "clobbered" boot loader etc.

    Hi, Aaron.

    You violated the Golden Rule of dual booting: Always install the newest
    operating system last. :>( The latest system's Setup file knows how to
    handle all the earlier ones. But WinXP's Setup has no idea what to do with

    If you had the Vista DVD, recovery would be pretty easy. Without it, it's
    still easy IF you have Vista's bootsect.exe file on your hard drive. WinXP
    will run this Vista program, but the file is not copied from the DVD's \boot
    folder to your hard drive by default. You must either run bootsect.exe from
    the DVD, or copy it to your hard drive and run it from there. If you don't
    have bootsect.exe, try here:

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

    Unless you've overwritten it, you still have Vista's hidden \Boot folder on
    your system partition.

    Sounds like good practice, but the reality is different :)
    Okay I have the Vista DVD after all, phew, and the Vista C: partition looks
    fine from XP. How do I now reinstall the boot loader ?

    Many thanks in advance,

  6. Stick the Vista DVD in and boot up using it. There is an option to repair
    it, which fixes the mbr. I did it myself last week.

    I ran the automated recovery on the DVD, which I now have by some miracle,
    but that did not work.

    I ran 'bootsect.exe /nt60 C:' but that did not work either.

    On attempt to boot it just says :-

    'Error loading operating system'

    which as far as I can remember from DOS days is a BIOS message.

    Sorry I did not reply directly earlier, I was sidetracked as normal.

    When XP installs, it always puts NTLDR in theMaster Boot Record of the drive
    you are installing it to.
    When Vista installs, it puts BOOTMGR where ever it feels like putting it. If
    Vista is the only OS on "C" drive then the repair using the Vista DVD will

    I had Vista installed, I wanted XP installed, on a separate hard drive, as
    Vista does not play nicely with MinGW32, so I wanted both.

    Vista was already installed, I wanted XP too. I still want my existing Vista
    installation, as otherwise I have alot of applications to reinstall.

    If I had unplugged my Vista drive before installing XP then replugged it
    back in after wards everything would have been fine. Then I could just
    choose which OS I want to boot from BIOS.

    Thats the reality of the situation. You maybe right in that I may have to
    reinstall Vista, but it would be great if that was not so and some solution.

    I cannot address "unplugging the Vista drive..." since I have no expereince
    in that route - both drives, to boot from BIOS, would have to be designated

    As you probaly know, XP uses Boot.ini as a DOS boot manager while Vista use
    BCD Store via WinPE. For duial booting - XP is (Oldest OS) is installed
    first - Vista is installed via XP and place files associated with its boot
    manager on the XP partition and modifires boot.ini to provide the OS boot

    Usually a third party utility such as VistaBootPro provides a solution.
    Another option may be BCDedit.exe. Microsoft's command line utility to
    modify BCD Store. Check the follofwing site:

    So re installing Vista deletes your APPs.

  16. From what I read you should be happy.

    Quite a something that one version of Windows destroys another.
