Latest PXELinux and exit to UEFI boot

[wdawson61]

Hi. We’'ve been trying quite exhaustively to get 2 different UEFI laptop clients (Acer X555LA and an HP 355G2) to boot Windows 10 /7 after exiting the PXE menu. We either get the dreaded boot loop, or a Chainloading failed - based on the “FOG PXE Boot Menu Configuration exit type.” Do we need to use a new version of pxelinux or the binaries in /tftpboot ?

PS> This is a completely new installation and we have not tried any otgher tasks such as imaging, etc, only intially booting the clients in the FOG menu.

Any help will be greatly appreciated !

Using PXELinux.0 is no longer recommended, at least since FOG 1.0.0 as we started working to support UEFI and Legacy devices.

@wdawson61 Welcome to the forums!

• Which exit types have you tried so far?
• Can you please post pictures of the errors?
• Which version of FOG do you use?
• Do other UEFI machines work properly?

We’ve tested 3 machines all of which are UEFI machines; the 2 mentioned the OP and a quite new Lenovo P70.

Thanks again.

We’re using whatever the FOG installer put there. I took a TCPDUMP of a boot session with the ASUS X555LA and noticed that the architecture type is Matching to the “Legacy” case in the dhcpd.conf file if thats significant. Here’s a link to the capture file:

Thanks.

@wdawson61 Hey, can you do that capture again using this process: https://forums.fogproject.org/topic/9673/when-dhcp-pxe-booting-process-goes-bad-and-you-have-no-clue

I see some strangeness in the previous pcap. The above filters will give us only the data we need. The malformed packets on the client side are interesting. From the data it looks like the target computer IS pxe booting OK in bios mode.

@wdawson61 Thanks for the pictures and testing. Great you made that network dump too! Looks like you are right, it is seen as platform=pcbios aka legacy BIOS. I guess this is CSM/BIOS compatibility mode in UEFI. See if you can switch to proper UEFI!
