How to Run Netboot

After installing the app, edit to add boot entries:

vi /var/lib/tftpboot/pxelinux.cfg/default

Making bootable images of various OSs is not trivial. It involves precise setup of files in a web server or NFS share or other way to serve files in your network (or in some cases, off the internet).

Example Configuration

Suppose that you want to boot a Linux OS over the network, say Fedora 22.

This is the configuration you need in /var/lib/tftpboot/pxelinux.cfg/default

label linux
  menu label Install or upgrade Fedora 22
  menu default
  kernel fedora22/vmlinuz
  append initrd=fedora22/initrd.img repo=http://dl.fedoraproject.org/pub/fedora/linux/releases/22/Workstation/x86_64/os

Then you need two files (vmlinuz and initrd.img) inside a directory called fedora22:

 cd /var/lib/tftpboot/pxelinux.cfg/
 mkdir fedora22
 cd fedora22
 wget http://dl.fedoraproject.org/pub/fedora/linux/releases/22/Workstation/x86_64/os/isolinux/vmlinuz
 wget http://dl.fedoraproject.org/pub/fedora/linux/releases/22/Workstation/x86_64/os/isolinux/initrd.img

With that configuration, you should be able to boot Fedora 22 off your network and install from it!

If course, rather then the repo being remote, you can also install from a local repo. For example, if you can make the one form the CD/DVD available in the file system, or via a local web server (e.g. a simple web app pointing to the repo). The configuration will need to change accordingly. See more examples of PXE Boot Configuration
