HD with Vista Won't Boot

Hi There,
I'm using HDClone 3.6 Basic.
I have a 160GB HD in 2x15GB and 1x130GB partitions. I cloned the 1st 15GB containing Vista to the 2nd 15GB (partition to partition mode). As I wanted to restore my Vista, I cloned back (restore) the 2nd 15GB to the 1st. After restart, Vista worked fine as expected.
I tried to clone the 2nd 15GB to another 80GB HD (partition to drive mode) and allowed HDClone to automatically resize the target drive. After restart, Vista won't boot on the 80GB HD and said something like disk partition failure or no system disk (I can't remember which one).
What's wrong?
Thank you.
Regards,
rma
