HDClone 3.7 - how to make bootable copy HD (Vista)

Hi,
I have tried twice to make a backup copy of my 120GB HD to a new 160GB HD connected to an USB port.
Cloning seems to go smoothly, but when I try to boot from the cloned HD (physically replacing the HD inside my laptop), nothing happens: after BIOS messages Vista will not start running
Some details
I was using HD->HD copy mode, HDClone 3.7 Standard
on HP Compaq 6510b laptop running Vista Business
(i) I allowed HDClone to ajust automatically for the larger HD
(ii) After cloning, I accepted the autmatic (default) adjustments HDClone suggested for the cloned HD
NOTE:
To make HDClone to recognise the internal HD, I had to adjust BIOS setting "Native SATA mode" to disabled. When trying to boot from the clone, I had this setting in it's original value "Enabled".
Question:
What settings at steps (i) and (ii) above will maximise my possibilities to get a bootable clone of my Vista hard drive? Or any other suggestions I should consider in order to make this work?
