thanks for the answers,
the scripted os install job feature is what i was looking for!
but apparently i ran into a problem when running the job, with my own unattended.xml or the sample ones from ghost.
When i run the job it says it is preparing the harddisk and quickly switches to error code 1 - error during script controlled os installation.
And then the System which was bootet over PXE, where i wanted to test it on, reboots.
What is the best way to debug this issue, which are the important logs for this kind of problem?
thanks
