Installation:From PXE env
The Preboot eXecution Environment (PXE, aka Pre-Execution Environment, or 'pixie') is an environment to boot computers using a network interface card independently of available data storage devices (like hard disks) or installed operating systems.
PXE was introduced as part of the Wired for Management framework by Intel and is described in the specification (v2.1) published by Intel and Systemsoft on September 20,1999. It makes use of several network protocols like IP, UDP, DHCP and TFTP and of concepts like GUID/UUID and Universal Network Device Interface and extends the firmware of the PXE client (the computer to be bootstrapped via PXE) with a set of predefined APIs.
The term PXE client only refers to the role that the machine takes in the PXE boot process. A PXE client can be a server, desktop, laptop or any other machine that is equipped with a PXE boot code.
As a reference (for sure no advertisement) the servers you can hire @ Hetzner have a PXE environment. The sequence/installation procedure i will describe here was based on experience on one of their machines.
