Lenovo ThinkPad E490 UEFI Problem
-
Hello, i’m having problem to boot PXE over UEFI notebook.
I allready have configured my DHCP server to provide ipxe.efi and appear the message “NBP file Downloaded successfully” but after this back to windows or boot menu.Need some help here
-
@cbittencourt Secure boot is turned off or on??
-
@cbittencourt Do you have other machines that properly PXE boot in UEFI mode?
You can try other binaries like
snp.efi,intel.efiorrealtek.efi. -
@Sebastian-Roth i have others notebook on same model but i already have tried before too.
About the others binaries, i just try randomicaly ? -
@cbittencourt Make sure your uefi firmware is up to date on that Lenovo. We’ve seen some pretty cruddy first generation firmware on lenovo systems in general. It sounds like the iPXE kernel is not wanting to start on that system.
There are a couple of other options we can try, but make sure your firmware is up to date first.

No I meant different models. Just to see if this is specific to the E490.

Yes, just try those and see if it makes a difference. And there is one more:
snponly.efi -
@Sebastian-Roth none of those 4 worked
@george1421 UEFI Bios Version: ROYET41W (1.24) - 2019-12-18 (on ThinkPad BIOS Flash update Utility says its up to date)i’m out of ideas

Well this is workaround #1: https://forums.fogproject.org/topic/6350/usb-boot-uefi-client-into-fog-menu-easy-way
Basically you are taking ipxe.efi from the fog server and placing it on a formatted usb stick in a specific directory with a specific name. Use the boot manager to boot from the USB stick. If it works then the issue is with the uefi PXE hand off to iPXE. If it fails then the firmware doesn’t like iPXE.
If it doesn’t work then we move on to workaround #2
But of course make sure secure boot is disabled. Any non-signed kernel will have booting issues if its turned on.

@Sebastian-Roth i can’t believe i didn’t search for that before ¬¬
It’s working now.
Omfg, i was so naive -
Thanks for help!!
@george1421 @Sebastian-Roth -
@cbittencourt So just for clarity you had secure boot enabled and you turned it off to resolve the issue?
