To boot your computer using a PXE server, you need a properly configured server and a network interface in your computer that supports PXE.
Configure the computer to boot from the network interface. This option is in the BIOS, and may be labeled
Network Boot or
Boot Services. Once you properly configure PXE booting, the computer can boot the Red Hat Gluster Storage Server installation system without any other media.
To boot a computer from a PXE server:
Ensure that the network cable is attached. The link indicator light on the network socket should be lit, even if the computer is not switched on.
Switch on the computer.
A menu screen appears. Press the number key that corresponds to the preferred option.
If your computer does not boot from the netboot server, ensure that the BIOS is configured so that the computer boots first from the correct network interface. Some BIOS systems specify the network interface as a possible boot device, but do not support the PXE standard. See your hardware documentation for more information.
