    uninstall dual boot with XP

    Hi,
    Before I do this, I just want to know if calling fixboot, then fixmbr
    will successfully switch the the bootloader back over to the ntloader
    from the Vista bce (or what ever it is called) bootloader so that I can
    boot back to my XP and repartition the Vista drive.



    Thanks

    Despite the "no response" I went ahead and did this, and low and behold
    I'm screwed. Needless to say I'm not just a little pissed off I'm
    really, really pissed off.

    Here's the steps:

    1) Install Windows XP
    2) Install Windows Vista on a clean partition
    3) Reboot to the recovery console and type:
    fixboot - OK
    fixmbr - results in a warning of nonstandard boot manager, continuing
    may corrupt partitions, went ahead anyways since I didn't really have a
    choice in the matter.
    4) Result is: Windows XP boots fine, no problem (phew)
    5) Delete Windows Vista partition
    6) Install Fedora Core 5 on the new space available from the deleted
    Windows Vista partition
    7) Reboot - boots to Windows XP, no sign of Linux

    It seems that I'm still using the BCD as the boot manager even after
    doing a fixboot, fixmbr. That sequence removes grub why does it not
    remove BCD?

    Now, since I deleted the Windows Vista partition I don't have
    BCDEDIT.EXE, so I can't even try to configure my boot manager to add new
    boot options!

    Is there some way to repair the BCD boot manager without installing
    Windows Vista?

    Microsoft needs to release and make apparent documents that describe the
    steps required to uninstall their freakin' betas!

    Looks like another reinstall of Windows XP, great I was really looking
    forward to that.

    By the way, if anyone is reading this that has not yet tried Windows
    Vista Build 53xx, don't bother, it's completely useless, there are no
    drivers, you can't even install Microsoft software like VS2005 because
    it craps out during the setup and the user interface is so half-baked
    it's completely unusable.

    I just have to reiterate, how is it possible that MS has released a boot
    manager that is not backwards compatible with earlier Windows versions?
    I cannot understand this.

    It should be - don't forget that sometimes they release patches for previous
    versions of Windows so that they are then compatible with a program ready to
    be released later on in the future.

    But the BCDEDIT is still a bit crap at times, so bare with it )

    I should probably mention that this step should have replaced the boot
    loader with GRUB, which didn't happen.

    Zack -
    I'm really impressed with your steadfastness, personally I'm not going
    near any beta or even release of Vista until the dual boot and backward
    compatibility problems with the BCD boot loader are resolved.

    Ok, after all this ranting, I'm feeling a bit like a jerk. It turns out
    that the Fedora Core 5 install failed to configure GRUB correctly. So, I
    don't actually know if fixboot, fixmbr really did switch back over to
    the ntldr. All I know is that Windows XP does boot without problems
    after doing a fixboot, fixmbr, after which you can safely delete your
    Windows Vista partition.

    Sorry for the rant.
