UEFI can't PXE boot
-
@yoshideoeuf undionly.kpxe is only for legacy clients, you must use one from *.efi collection on /tftpboot directory of the fogserver that is working as boot server, I dont know how to do it but maybe you mas configure the windows dhcp server to send different files, on arch dependant
Maybe this links can help you…
-
@eduardotseoane Yes, I already use ipxe.efi for UEFI, but it doesn’t work. Do I have to remove the undionly.kpxe ? Or maybe I just need to type /tftpboot/ipxe.efi instead of ipxe.efi ?
-
@yoshideoeuf NO, you must configure dhcp for UEFI/BIOS Coexistence, take care because efi clients don’t work on all machines, each machine type has his efi client, with NIC chip dependency, the same for legacy.
I don’t work with Windows dhcp server, (are you using it?) so I don’t know how to do it exactly
You must do that when client has UEFI archs send the correct efi file, filtering by Arch and by vendor…, when client has BIOS Archs, you must send the correctl legacy file, filtering by Arch and vendor too.
Read the urls before posted with attention, i think that it has a how-to to solve your problem… with Windows 2012/2008 dhcp server, if it’s your case…
Read this with attention, and if you can post a photo showing the error:

@YoshiDeOeuf Your Windows DHCP config looks ok in first sight but there is more to it. I am not an expert in this but I do remember a topic here in the forums not too long ago where someone seemed to have the right settings but one final piece was still missing. Give the forum search a try or maybe @george1421 still remembers as He was the one who was able to help and fix the case back then.
Web GUI issue? Please check apache error (debian/ubuntu: /var/log/apache2/error.log, centos/fedora/rhel: /var/log/httpd/error_log) and php-fpm log (/var/log/php*-fpm.log)

The final bit was / for when the OP of that thread used the bios_and_uefi coexistence process he forgot to activate the policy. I don’t have a windows dhcp server in front of me, but there is a definite option to enable the policy or the scope. Once that was done then the dhcp server was dynamic in the boot file name according to the policy/rules.

@george1421 Thanks!
@YoshiDeOeuf Just found it, find all the details on this story in this topic: https://forums.fogproject.org/topic/15102/uefi-bios-coexistence-help

@eduardotseoane I already red these urls many times, and I use a Windows Server 2012 R2 as I said, maybe i need to put another .efi instead of ipxe.efi ?
-
@george1421 My policy is enabled :
I created this policy like in this tutorial : https://wiki.fogproject.org/wiki/index.php?title=BIOS_and_UEFI_Co-Existence#Using_Windows_Server_2012_.28R1_and_later.29_DHCP_Policy

Well from your initial post it very much sounds like PXE boot for legacy BIOS machines work but not for UEFI mode ones in general. Sure there are some machines that don’t properly work with ipxe.efi but they usually still load it and then fail to get an IP via DHCP within iPXE or something like that.
Sure you can try snp.efi and snponly.efi but I doubt it will help in your case.
I get an “no bootable device found” error.
Do you see it trying to pull an IP and PXE information from the DHCP at all? Without knowing what stuff you actually see on screen it’s kind of hard to help.

Hello,
Back to this problem, so I followed the tutorial with UEFI PXE boot with options 60, 66 (fog IP) and 67 (ipxe.efi) as shown in my previous messages.
I took a screen of what I get on the computer i try to PXE boot.
192.168.3.1 is the IP of the computer.
Do you think he’s able to reach the fog server at least, or maybe the problem is the boot file ?
Thank you in advance
-
@yoshideoeuf This is saying the dhcp server did not send the boot file name or received a proper offer packet from the dhcp server. At this point its not a fog server issue, but communication between dhcp server and client computer.
-
@george1421 I can ping without problem the DHCP server from the computer client
-
What is the netmask of the DHCP server and the PXE client (considering the 192.168.2.x and 192.168.3.x addresses of your screenshots)?
Asked in another way: is there a relay agent between the two?Also: is Secure Boot disabled on the client?
-
@peterl it’s /24 for both

So do you have a dhcp helper service enabled on the router between .2.x and .3.x subnets?
Do you have the dhcp option 66 and 67 filled out for both subnets?
