Just for the notes: I pushed a fix for populating the “Working with node” column properly. But still I don’t think this is causing @TheDiskDrive’s issue. Please post a picture of the error you see and we should be able to help.
You are trying to boot the I.S.O. over the network.
The way I recommend you do this for pxe access in your company is to extract the content of the iso to a folder of your choosing then give proper access to the folder for the fog server using the exports file.
examples can be provided if im understanding what your trying to do?
