3. Save BIOS and reboot system. The BIOS will show “Checking Media Presence......”, if

system is not connected PXE server, it will show “No Media Present......”

PXE boot usually does not allow for OS installation over network as the PXE client will only

load a single file from the boot server. Similarly, booting Linux over network is usually a

two stage process. In the first step, a boot loader such a grub or mini OS such as SysLinux

are loaded via PXE from the boot server. The boot loader or miniOS then load the actual

target OS which usually consists of multiple files which decompressed and installed into a

RAM disk. The detailed process and required configuration of such network install will

heavily depend on the target OS and boot loader / miniOS used. Please refer to the related

documentation available.

PXE boot requires a DHCP server and a TFTP server in the network to complete. DHCP

Server and TFTP server are commonly run on the same machine and collectively referred

to as “boot server”. Setting up such a boot server implies a couple of steps. How-to guides

for setting up Linux as PXE boot server are available on the internet, e.g.

https://www.debianadministration.org/article/478/Setting_up_a_server_for_PXE_network_

booting.

Please note that it is recommended to setup a separate network / subnet

for network booting as the DHCP required for PXE booting may conflict

with existing DHCP servers in your network.
