Use bootcfg <http://support.microsoft.com/kb/317521> to create
boot.ini. Copy ntldr and ntdetect.com from the XP CD to C:\.
 
i got the simple way to recover the dual boot.
case 1: if vista installing auto formated c: and installed , XP installed in
deferent partion before. the XP can't be boot. Then copy ntldr,boot.ini
,NTDETECT.COM 3file to boot driver(C:).
excute (Drive:\Windows\system32\)
Bcdedit /set {ntldr} device partition=c:
Bcdedit /set {ntldr} path \ntldr
Bcdedit /displayorder {ntldr} /addlast (or addfirst)

case 2: if XP is installed after vista installing,
excute Drive:\boot\Bootsect.exe /NT60 All
Bcdedit /delete {ntldr} /d (if you don't like the <early version windows>
choice)
Bcdedit /create {ntldr} /d "<Windows XP>"
Bcdedit /set {ntldr} device partition=c:
Bcdedit /set {ntldr} path \ntldr
Bcdedit /displayorder {ntldr} /addlast (or addfirst)
