Figured out how to boot the computers in legacy so we went that route instead of figuring out how to do it with UEFI. Thanks to all who helped, especially @Tom-Elliott, who is a very cool dude. Happy to finally get to work!

@Wayne thanks for the link. I tested from a Windows machine and was able to successfully download undionly.kpxe from the fog server. So this means tftp is working correct? Anyone have any idea why it still doesn’t want to boot and what’s up with the weird mac address?

@Junkhacker It’s a Lenovo C260. The mac address isn’t 01:01:01:01:01:01. Other computers fail to boot as well.

So @Tom Elliott ended up connecting to my server for awhile and he made a lot of progress. Awesome guy btw. I’m not sure all he did, but the clients are now booting to pxe, but they hang before booting.

Waiting for link-up on net0… ok
Configuring (net0 01:01:01:01:01:01)… Error 0x040ee186
Failed to get IP, Booting back to bios

Any thoughts?

A video on it just in case: https://www.youtube.com/watch?v=oKFCUGnjUSE

More info: At first it wasn’t giving the option to press F8 for boot menu, after adding the "dhcp-boot=pxelinux.0,X.X.X.X " to Untangle it does now show up, grabs an IP, but then fails to load with the error messages in the original post.

@Tom Elliott I disabled the firewall on Untangle and the problem still persists. I’ve researched up and down and from what I see on the untangle forums other people who have gotten fog running have just had to add dhcp-boot=pxelinux.0,X.X.X.X to their dnsmasq (Config > Network > Advanced > DNS & DHCP) and that fixed it. I’m not sure where to add next-server as on untangle a lot of the config files get overwritten due to the gui. It looks like it is possible but in my case I’m not sure. I’m perhaps in over my head here…

@ch3i Hi! It is 1.2.0

Hello all! I’m currently running FOG on top of Ubuntu Server 14.04 on an existing network. The network has an Untangle 11.1 server. I have setup fog with the correct setting according to the wiki (setup correctly pulled the IP, didn’t point towards dhcp server, dns, and said no to FOG running its own DHCP server). I then booted the client and it wouldn’t connect, I had the error:
PXE:T01 File not found.
PXE: e3B: TFTP file not found.
PXE:M0F: Existing PXE ROM.

So I began to search the internet for how to fix it. I added dhcp-boot=pxelinux.0, image-01, 192.168.1.140 to my untangle server under advanced settings but the problem persists. I have been trying for about a week now to get this to work and just can’t seem to make any progress. Any help will be greatly appreciated!
