When deploy is started machine reboots...

First of all, we have upgraded our Snap Deploy installation to latest version :-)

We have no trouble booting different machines with the Acronis PXE and then take a master image of them. When we afterwards will boot a machine with the PXE server, everything Works fine until the deploying starts and then mackine reboots. If we boot machines with the a CD with the agent on it, we get an error saying something about the target drive is different. We are using the Acronis system, to install new HP machines, and this is very irritating that it not working.
We cannot garanti, that the harddrives are totally the same every time, but should Acronis not deal with that?

Looking forward to your answer :-)

Peter.
