PXE Boot doesn't work on HP ProDesk 400 G7

DepecheMidi · ‎05-21-2021

Hi,

On the Prodesk 400 G7, it's not possible anymore (unlike previous desktop models) to boot on PXE.

We had all the previous models of this serie in our company and always could boot on PXE to install our Windows 10 wim images.

The problem has been submitted in this topic a few times ago and it seems there is no solution and answer from HP:

I've tried everything : all the solutions of the topic above (reset BIOS, disable TPM,...), nothing worked.

The factory version of the BIOS was 02.05.01. I've tried rollback towards 02.04.01 : nothing changed.

Idem with 02.02.00 and 02.01.01 versions.

Does anyone know if there is a fix? Or is it the new "ordinary" HP BIOS with no PXE boot?

Thanks.

Hello,

I have the same problem, it is impossible to launch a PXE boot on the model.

I tried to disable the TPM chip and boot security on each version of bios (02.04.01 and 02.05.01) and several other handling in the BIOS

In addition, There is no support for legacyDOS, Windows, or Linux configurations (Impossible to test a legacy Boot PXE).

I need to know if the model doesn't proprose this option or know a resolution.

(For my part it compromises a renewal of several hundred computers).

Thanks

I made a phone call to HP last week and we just had an answer by mail from them last friday:

Intel is no longer providing legacy option ROMs for legacy operating system support except for network devices:

Legacy BIOS Boot Support removal from HP computers:

As you can see, there is (and will be) no other solution but to boot in UEFI mode...

the network driver does not work during PXE boot

we added the NIC driver in the wim image boot for detection and its work
