First of all, I consider myself too low on Tech-Knowledge so please pardon my noobness. I used MDT 2010 to create an unattended Windows 7 installation, having some applications to be installed. All is fine except for one problem. During the install, The MDT during PE does not ask for the customization of Drives i.e. Formatting and Partitioning. If the installed is a Fresh install, MDT by default wipes out all the drives and creates only one partition of all the available HDD space. Now the problem is I don't want it like this. I have been searching for the solution for 26 hours. I have been through a lot of scripting and XML coding etc etc, but I ain't really in to these. (again pardon my noobness) Then I found cluberti's post This was what he said I Installed Partition Wizard on my computer. I copied the Partition Wizard installed folder and its files to the SCRIPTS folder of the deployment-share. I then wrote a .cmd file, start /w X:\Deploy\Scripts\Partition Wizard\PartitionWizard.exe. Saved this file to the SCRIPTS folder. In the Task Sequence, Under the New Computer Only group, I added a Run Command Line with the contents cscript.exe "%SCRIPTROOT%\PartitionWizard.cmd" Completely Rebuilt Boot Images, but when the deployment commenced, the Partition Wizard did not start and gave 7 errors. Can anyone help???
