Puff, this is heavy stuff. I am just doing unattend for a few days now ; trying to unattend server 2003 with a slipstreamed sp1. But having a lot of trubbles; also with the diskpart. i just don't know how to use it. tried reading a lot but í don't get it working. what i would like to do is - when staring the unattend- 2 partitions are created; a c with the installation from 9 giga; and a d that should use the rest of the available memory. Both partitions should be dynamic volumes. Because i am using different sized harddisks, the d partition can be for 1 server 9 giga and for a other server 21 giga. Also, the cdrom should be given the Z Hope someone can help me; i am stuck and totally blacked-out.
