In case that there are several devices which have to be set up identically (e.g. RPis, Nucs, ...), it might be helpful to just clone memory disks, once the first one is set up completely. Clonezilla is a tool, addressing exactly this. The following describes one way of using Clonezilla which has proven itself for our purposes.
Clonezilla is an operating system and can thus be used via a bootable USB-stick. In the CPM Lab you will find a black one which contains this already. (PICTURE)
To start Clonezilla you might have to change some properties in the BIOS. Plug in the USB-Stick containing Clonezilla and start the computer. You will get into the BIOS by pressing F2.
