The primary task of OS deployment involves capturing the OS image. OS imaging is a process to capture the image of a specific OS from the desired system along with the set of applications. The captured image will be stored in an image repository, a network share from where images will be deployed to client computers. This OS image can be deployed on a new bare metal computer or an existing system with an OS.
For the above cases you can decide on the desired system for each team/students and capture different images and store it in the image repository. This captured image can be deployed across the machines of new joiners/students.
ManageEngine Desktop Central offers two types of imaging techniques to capture images, online and offline imaging.
Online imaging is when an active system is remotely imaged without any user intervention. To perform online imaging in a system, image creator components will be installed by OSD Server(On-premises)/ Distribution Server(Cloud). This image creator component will capture the image of the system. Basically, it is the imaging of the OS of a computer where the OS is active and running.
In offline imaging, the system is stopped and booted into Windows Pre-installed Environment (WinPE). Imaging is later performed using the WinPE component. WInPE component is stored within a media (USB, PXE or ISO). Basically, it is the imaging of the OS of a computer which is actually shutdown.
