Tamir moved page [[UEFI PXE boot to Linux Mint]] to [[Application note - UEFI PXE boot to Linux Mint]]
== Overview ==
* In this tutorial you will be able to create PXE server on your PC that allows you to boot multiple distributions directly from ISO image using Ethernet connection only. * The diskless computer (or diskless node) you want to boot will be called the Client* The computer that holds the ISO images and provides DHCP, TFTP and NFS services will be called the Server.** Server is running recent Linux Mint or Ubuntu distributions** Server has 2 Ethernet ports: eth0 connects to the internet, eth1 will be connected to the separate network with diskless nodes * As example we will boot the client from the linuxmint-19.1-cinnamon-64bit.iso stored on the Server
== TFTP server ==
* Reload tftpd-hpa service and verify it's running:
<pre>
$ sudo systemctl restart service tftpd-hparestart$ systemctl status service tftpd-hpastatus

== ISO images ==
* Download desired ISO image, for example:
<pre>
$ mkdir -p ~/iso/linuxmint/
$ wget http://mirrors.seas.harvard.edu/linuxmint/stable/19.1/linuxmint-19.1-cinnamon-64bit.iso -P ~/iso/linuxmint/
</pre>
* Copy downloaded ISO image content to the TFTP directory
<pre>
$ sudo mkdir -p /mnt/loop
$ sudo mkdir -p /var/lib/tftpboot/iso/linuxmint-19.1-cinnamon-64bit.iso
$ sudo mount -o loop ~/iso/linuxmint/linuxmint-19.1-cinnamon-64bit.iso /mnt/loop

== Prepare the client ==
* Power-on the client
* Enter the BIOS Settings by pressing [Delete] number of times
* Set Advanced -> Network Stack Configuration -> Ipv4 PXE Support to [Enabled]
* Save & Exit
* Thats all, after 1-2 minutes you should see the Linux Mint 19 desktop on your client's display
== Enable debug (optional) ==
* /var/log/syslog will represent debug info on the server side:
<pre>
$ tail -f /var/log/syslog
