Boot package is created but when installing the Automation Folder, it shows the following error: "No appropriate BootWorks NIC found. Use Boot Disk Creator to create a BootWorks install package".
Mostly the reason is because either permissions on the temp folder or the temp folder is full.
It's also possible to push the Automation Partition install using a Software Delivery task, instead of the default Automation Installer task.
To do create a Software Delivery Task, use the correct file under C:\Program Files (x86)\Altiris\eXpress\Deployment Server\BWPkgs\<WinPEVersion>\x64
If it doesn't help, you can check the network adapter driver:
