Secure Boot is Off. I promise and I hope I’m smarter than that. Time will tell I guess.

But, I will admit, I know next to nothing on iPXE, UEFI boot and FOG. This is my first go at it. I was able to image (capture/deploy) multiple times on this setup to systems that used Legacy ROMs and PXE. I’m probably making some seriously wrong assumptions about iPXE. And I apologize if I’m asking some very noob questions. Just not finding information quickly in the WIKI around troubleshooting this particular error.

So, I’m using a Ubiquiti Security Gateway for the DHCP server. I’ve used both Windows DHCP, and other Firewall stacks and all have worked. I suspect it’s the undionly.kpxe file that I’m using?

And it’s not network. I’ve got an unmanaged switch sitting between FOS and the host in question so all traffic stays local except for the DHCP ARP packet.

Boot mode is UEFI with Secure Boot Off. ACHI is turned on, with RAID off. When I select the Boot Options menu when the PC begins it’s BIOS POST, my boot options under UEFI BOOT are Windows Boot Manager, Onboard NIC (IPv4) and Onboard NIC (IPv6).

When I select Onboard NIC (IPv4) I get the following:

Checking Media Presence
Media Present
Start PXE over IPv4
Station IP address is 192.168.1.251

and then the screen flips so fast I had to video it so I could capture what happens next…

Checking Media Presence
Media Present
Downloading NBP files…

and then…

Press F1 key to retry boot
Press F2 key to reboot into setup
Press F5 key to run onboard diagnostics

OK, tried that and what I see now is the UEFI boot fails with no error message.

Hello,

Been struggling to get a series of Dell OptiPlex 7050’s with PCIe M.2 drives to work properly with FOG. The only way I can get the PXE loader to recognize the drives is switch the Boot Options to Legacy rather than UEFI. Secure Boot is turned off when Boot Options are set to UEFI. Running Fog 1.5 with Kernels 4.15.2.

These systems were purchased in Feb '18. They are running BIOS 1.8.2.
