If you just want to PXE boot the installer, you're probably better off 
just grabbing one of the netboot images from here: 
http://gb.archive.ubuntu.com/ubuntu/dists/trusty/main/installer-amd64/current/images/netboot/

I use the netboot.tar.gz image, and serve it via tftp to my client 
machines.  To do this, you'll need a tftp server running on your dhcp 
server (I use tftpd-hpa from the Ubuntu repos), then untar the netboot 
tarball into your tftpboot directory.  Then you need to add a filename 
option to your dhcpd config.  I use something like this is (with isc dhcpd):

     host foo {
         hardware ethernet 12:34:56:78:9a:bc;
         fixed-address 10.0.0.123;
         filename "/trusty64/pxelinux.0";
     }

(I've untarred the netboot image to the trusty64 directory under my 
tftpboot).

I've found this approach to be very reliable - it's been how I install 
all my machines for quite a while now.

Hope that helps...

thanks,
Alex
