Last Modified: 2012-06-27
I have a Windows XP SP2 installation.  Later i installed Windows Vista on a diferent partition.  I then decided to get rid of windows vista.. and when into the XP operating system and formatted the Vista partition.  The only thing that's bothering me is that i still have the bootprompt from windows vista.  I know that Vista uses a new bootloader, how do i get rid of it?

    With Vista gone it shouldn't be problem. I assume that you didn't use any 3rd party apps to dual boot the system and that you edited the "Boot Configuration Data Store Editor" using bcdedit.exe?

    Either way it shouldn't cause you an issue. If you right-click on 'My Computer' > 'Properties'. Click on the 'Advanced' tab and click on the 'Settings' button for Startup and Recovery.

    Next there's two ways to accomplish what you're after. You can either select XP to be your default operating system and set the 'Time to dislpay list of operating systems:' to zero.... OR you can edit the boot.ini file manually by clicking on the 'Edit' button.
    Assuming you've only got on disk and that your Windows partition is C:\Windows then your boot.ini file should look like this:

    [boot loader]
    [operating systems]
    multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /noexecute=optin /fastdetect

    Click 'File' > 'Save' and you should be done!

    Goto Start>Run>msconfig>Boot.ini
    and click on Check All Boot Paths
    does it ask to Remove an Invalid Entry
    say Yes and let it to finish
    restart and now it shud boot straight into the valid installtion

    And you can edit the Boot.ini manually also to remove the other OS entry.

    fixmbr from the recovery console will reset your boot menu to the XP default settings, I've used that many times to get rid of linux boot menu (grub)

    Tried the first solution but i still get the Windows Boot Manager screen, with windows vista as the default boot.  I have to manually select the legacy operating system options in order to get into XP.

    I checked the msconfig also, but the only boot entry is windows XP.

    Any other suggestions?

    Try this:

    You'll still be using the Vista Boot Manager but can modify its settings. VistaBootPro runs under XP as well as Vista.

    fixmbr may work. I haven't tried that approach, so can't say for sure.

    Ah sussed it. I replicated your problem, the vista BCD remains on the XP partition regardless of whether Vista is still installed.
    The quick and easy way to get rid is go over to - with that software you can revert from the Vista BCD back to the XP boot.ini which solves your problem.
