Dual boot Win 7 64 bit/Windows XP/Windows XP with 3 gb switch

#1
Hello
I recently made my xp system to dual boot with win 7 also
both operating systems are on the same drive (but on a different partition)
I didnt have any problem (the dual boot menu that win7 made works normally to allow both operating system to boot when selected) except that now I dont have the option to use win xp with the 3GB switch
so I tried easybcd but I cant seem to get results
From what I read after selecting win XP I should get a second menu to chose between standard xp and xp with the 3GB switch
the boot ini (now edited by easybcd) looks like this:

; This boot.ini was automatically generated by NeoSmart Technologies' BootGrabber.exe
; Use EasyBCD from EasyBCD - NeoSmart Technologies to manage your bootloader


[boot loader]
timeout=20
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Windows XP" /NoExecute=OptIn /fastdetect
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="XP 3GB" /NoExecute=OptIn /fastdetect /3GB

the files that should be placed on the winXP partition seem to be correct:
ntldr
ntdetect.com

But unfortunately no menu appears and win XP boots directly when selected (as it was before using easybcd)
do you have any idea that would help?
Thanks in advance
