OS Selector Multi OS Problem

Hi

I need to Install 3+ OS on a Notebook that will be used to test Programs on different OS

1st Win 7 x64 on the intern HDD (no problem :p),

2nd Win 7 x86 on a Esata drive (50GB pratition) (no problem)

3rd Win XP x86 on a Esata drive (50GB pratition) (no Problem) OS Selector does it´s job.

Now comes the tricky part i want to clone the Win7 x86 partition and the Win XP partition and restore them multiple times on the Esata drive to get e.g. 1x Win 7 x64, 3x Win 7 x86 and 2x Win XP x86.
I use a software that can restore my image with or without MBR (ShadowProtect) but either OSS can´t find the restored OS or some other System gets kicked out and OSS can´t find it anymore.

Is there a solution for my Problem or is it impossible to use a cloned OS multiple times with OSS?
