    before any change:
    C:\Windows\system32>bcdedit

    Windows Boot Manager
    --------------------
    identifier {bootmgr}
    device partition=C:
    description Windows Boot Manager
    locale en-US
    inherit {globalsettings}
    default {current}
    resumeobject {e7ec40e3-bb2f-11df-b8ff-a397d96de083}
    displayorder {current}
    toolsdisplayorder {memdiag}
    timeout 60
    resume No

    Windows Boot Loader
    -------------------
    identifier {current}
    device partition=C:
    path \Windows\system32\winload.exe
    description Microsoft Windows Vista
    locale en-US
    inherit {bootloadersettings}
    osdevice partition=C:
    systemroot \Windows
    resumeobject {e7ec40e3-bb2f-11df-b8ff-a397d96de083}
    nx OptIn


    I tried using BCDEDIT
    C:\Windows\system32>bcdedit /create {ntldr} /d "Win XP Pro 32 - iei-a64"
    /TYPE N
    TLDR /device partition=D:
    The device entry type specified is not valid.
    Run "bcdedit /?" for command line assistance.
    The operation completed successfully.

    However

    C:\Windows\system32>bcdedit /create {ntldr} /d "Win XP Pro 32 - iei-a64"
    An error occurred while attempting the specified create operation.
    The specified entry already exists.

    what is the proper way to add a new entry for the xp partition D: that used
    to be C:?

    thx for replying


    after exec the 3 BCDEDIT cmd,
    I was able to reboot and choose earlier version...
    it prompted with something about corrupted or not found ntldr

    I than press ctl-alt-del and boot into vista Ult 64,

    @REM copy files from XP partition to Vista
    copy d:\boot.ini c:\
    copy /b d:\ntdetect.COM c:\
    copy /b d:\ntldr c:\

    reboot again. this time no complain, and Xp pro came up

    not sure if all the 3 files are required but definitely ntdetect.com and
    ntldr is required in Vista partition with the was the bcdedit was setup

    Now I can install the usb fax modem for occasional use with the x32 drive
    that I have. I wish I don't have to used winxp but with smart link chipset
    there is not much of a chance getting x64 device support.

    thx again
