add boot entry to dual boot with existing XP primary partition



before any change:

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"
TLDR /device partition=D:
The device entry type specified is not valid.
Run "bcdedit /?" for command line assistance.
The operation completed successfully.


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 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
