@JJ-Fullmer I tried to do so but when I click on download I get an error, after the download I have a generic error:

EDIT:
@Tom-Elliott I’ve changed this conf file:
/etc/dhcp/dhcpd.conf

class "Legacy" {
    match if substring(option vendor-class-identifier, 0, 20) = "PXEClient:Arch:00000";
    filename "undionly.kkpxe";
}
class "UEFI-32-2" {
    match if substring(option vendor-class-identifier, 0, 20) = "PXEClient:Arch:00002";
    filename "i386-efi/ipxe.efi";
}
class "UEFI-32-1" {
    match if substring(option vendor-class-identifier, 0, 20) = "PXEClient:Arch:00006";
    filename "i386-efi/ipxe.efi";
}
class "UEFI-64-1" {
    match if substring(option vendor-class-identifier, 0, 20) = "PXEClient:Arch:00007";
    filename "ipxe.efi";
}
class "UEFI-64-2" {
    match if substring(option vendor-class-identifier, 0, 20) = "PXEClient:Arch:00008";
    filename "ipxe.efi";
}
class "UEFI-64-3" {
    match if substring(option vendor-class-identifier, 0, 20) = "PXEClient:Arch:00009";
    filename "ipxe.efi";
}
class "SURFACE-PRO-4" {
    match if substring(option vendor-class-identifier, 0, 32) = "PXEClient:Arch:00007:UNDI:003016";
    filename "ipxe.efi";

I’ve replaced everywhere snponly.efi with ipxe.efi, but the result is the same…

@george1421 yes, I can confirm I’ve followed the instruction with no errors…

Update:
I’ve also follow this instruction:

with no luck

Hi again, and thanks for your help.
Here are some news:

• updated kernel from GUI: new kernel 6.8.1 -> same black screen, but after the old line now I have a new one:
  EFI stub: Measured initrd data into PCR9

• switch branch to “working-1.6” -> Now i have a cool new GUI but the same error

• Log:
  I don’t have this path: /var/log/php-fpm/www-error.log
  but only these:
  /var/log/php8.1-fpm.log
  /var/log/php8.1-fpm.log.1
  with no useful info (i think)
  All the logs that are in this path: /opt/fog/log doesn’t grow when i try a PXE boot…

I think that I should follow george1421 suggestion rebuilding iPXE and I’m reading this instruction:

Thanks again to all!

Hi All,
I’ve configured FOG (1.5.10) on Ubuntu 22.04 LTS, and I correctly create an image via PXE of a Dell Precision 3460 (the OS of the 3460 was on an NVME).
The FOG server manage DHCP and TFTP and it works like a charm.
Now I have to manage an HP Z8 Fury G5 Workstation Desktop but if I try to boot it via PXE it stuck on a black screen writing “EFI stub: Loaded initrd from LINUX_EFI_INITRD_MEDIA_GUID device path” after I choose: Quick or Full Registration…
This is not a network problem because the Z8 and FOG are connected on the same switch that I use only for this project.
I think that this could be a problem of linux driver, on the Z8 I have an RTX A5000 and the OS (windows) is on a NVME connected through a PCI.
In the BIOS Raid mode is disable, and AHCI/Uefi is enabled.
Can someone please help me by directing me to some documents?
I haven’t figured out how to check the PXE logs on Fog, maybe there is some log that can help me…
I don’t know if this could help, but here are some info about the disk:

Thanks!
