I've managed to create a few unattended install CDs which install all my apps and drivers, which is cool. However I'm now trying to improve things slightly and use BartPE to launch the install, so I can control the partitioning of the Disk etc. The problem I've got is I run the following command to start the installation: "%systemdrive%\XP\I386\winnt32.exe" /syspart:c: /tempdrive:c /unattend:"%systemdrive%\installs\winnt.sif" /makelocalsource After the restart Windows installs, however the CMDLINES.TXT file isn't processed, neither is my modified SVCPACK.INF, so no Hot Fixes or Apps install. Any help would be greatly appreciated.
