Vista: How to Uninstall Vista on Dual Boot Machine

Posted November 2, 2005 by MickeyMouse in Microsoft Vista

So you have vista on your dual-boot? As vista has its own bootloader, you’ll need to follow these steps to remove it.


Dual-booting with vista can be a little tricky to remove because of the new bootloader.

Playing with dual-boot systems has killed many people’s hard drives. I would suggest massive back-ups before you try to remove part of a dual-boot system. If you mess up, you might be unable to boot to any of your partitions. You do this at your own risk.

Here’s the basic steps you need to do:

    1. Backup, backup, backup
    2. Reboot and Boot to your XP CD-ROM
    3. Start the Recovery Console
    4. Run Fixboot
    5. Run fixmbr to reset the master boot record
    6. Exit the Recovery Console
    7. Reboot
    8. To remove the extra entry, edit the boot.ini file to remove the “Microsoft Windows Longhorn” entry.
    9. Format Your Vista Partition
