Multiboot and chameleon v2

Hi all, as in subject, i have a problem...
I have installed first, winXP Pro, then Windows 7 and finally macOSX

So i have 3 primary partitions:
1 = WinXPRO NTFS
2 = Windows NTFS
3 = MacOSX EXT+

...and a logical drive formatted in NTFS into an extended partition.

I have upgraded the bootloader to the new v2 chameleon version, and now i have an issue:

When i select the Windows 7 OS, i have BOOTMGR missing error,
When i select macOSX, all goes well
When i select Win XP PRO, i go into a text-bootloader (win7 bootloader i think), where i can select both, win7 and winXP, and they works well.

Into boot settings of Win7 (under advanced system properties) i see no settings, all white than win xp pro

what do you think?.. if i replace the bootmgr on win7 partition.. cannot i anymore boot from macos??.. (i have also a bootable gparted usbpen in the case..)
