We successfully UEFI PXE booted a Lenovo laptop to the OSD menu. However, we're experiencing challenges UEFI PXE booting HP laptops like the HP840G2. Here's what we tried with the HP840G2.
- Update BIOS with latest firmware.
- Disable secure boot in the BIOS.
- Enable UEFI Hybrid (with CSM) in the BIOS. Also attempted a test with UEFI in Native mode.
After pressing F12 during boot up we are seeing the message in the screenshot (shown below) for a short period of time. The computer then reboots into Windows from the local hard drive.
Any assistance or guidance for successfully UEFI PXE booting an HP laptop into the OSD menu would be greatly appreciated. As a side note, we are NOT currently using DHCP options or IP helpers as the OSD bare metal server is on the same subnet as the client.
