I'm trying to set up PXE in order to install Ubuntu 13.10 Server x64 through local network. So far, I can boot through PXE and, when using pxelinux.cfg/default provided by default, be able to install Ubuntu by downloading it from a mirror.

I want to be able to install Ubuntu from NFS. I edited pxelinux.cfg/default like this:

1  # D-I config version 2.0

2  default ubuntu-installer/amd64/boot-screens/vesamenu.c32

3  menu title Ubuntu setup

4  label ubuntu-13.10-server-amd64

5          menu label ubuntu-13.10-server-amd64

6          kernel 3.11.0.18-generic

7          append netboot=nfs initrd=install/initrd.gz nfsroot=192.168.1.75:/↵

   exports/ubuntu-13.10-server-amd64 ip=dhcp rw

• 192.168.1.75 is the IP of the server I use for DHCP, DNS and NFS,


• I got the kernel 3.11.0.18-generic by running uname -r,



• showmount -e 192.168.1.75 gives:

  
  
  

  
  

  Export list for 192.168.1.75:

/exports/ubuntu-13.10-server-amd64 192.168.1.0/24

  
  

  
  
  

  The directory contains the contents of the original ubuntu-13.10-server-amd64 image.

When booting from PXE, I get the original screen (see screenshots below), then another one. Pressing Tab shows the command:

3.11.0.18-generic netboot=nfs initrd=install/initrd.gz nfsroot=192.168.1.↵
75:/exports/ubuntu-13.10-server-amd64 ip=dhcp rw

Pressing Enter does nothing.

I imagine there is something wrong with my changes of pxelinux.cfg/default.

What's wrong with it?

Is there a comprehensive documentation of the options to set?

Are there logs which can help understanding what is wrong?
