I've been experimenting with PXE netboot with TFTP for the last few days and I have successfully setup everything except the preseed. I can see that Ubuntu (versions 14.10-15.04, amd64 and i386) successfully pulls the preseed.cfg from my web server and loads it, but it still runs the interactive installer. Here are my boot options:

The one that I'm trying to get working is the Ubuntu 15.04 (64-bit). I've been changing boot options that many say have fixed this problem but to no avail.
I don't want to paste my whole preseed.cfg here because I think it's a bit too long but I pasted it here: http://pastebin.com/0KRUvMcB
Does anyone have any ideas?
