I need to set up an automated testing system that cleans the system between installs and tests. Can an unattended windows installer be started from a running windows instance? I know that putting the XP CD in while in windows allows you to 'install' in a way that creates a temporary boot drive with the installer files, then reboots into it to continue the installation as normal. If I can have my scripts load an iso and kick it off, and have the runonce start up my scripts on the other side, I'll be set. So, will it allow this? At the very worst case, I can have a gui interaction tool poke the windows based interface, as long as it completes unattended after rebooting. Thanks for any info.
