You can find the first part of the instructions in the entry “Basic setup of toolstar®bootcast PXE environment”.
Option 1: .ISO files
To boot a Windows ISO, please enter the following into the user.bootcast.mini file or change the entry in the sample file so that the path \windows\isos\windows.iso points to one of your ISO files . The bootcast EXE directory is the starting point and the paths are always relative to this point in the hierarchy.
[bootset.win.install.iso]
caption = "start Windows PE (ISO)"
"tftp:*" = "winpe:iso:.\windows\isos\windows.iso"
Option 3: Unzipped .ISO files (individual files)
To boot individual files unpacked from an ISO file, please enter the following in the user.bootcast.mini file or change the entry in the sample file so that the path \windows\files points to a directory in which the unpacked files are located. The bootcast EXE directory is the starting point and the paths are always relative to this point in the hierarchy.
[bootset.win.install.files]
caption = "start Windows PE (files)"
"tftp:*" = "winpe:dir:.\windows\files\" # Use unpacked ISO file
