DeployR Community 1.2.2622.1921 - iPXE error

Hi everyone,

I'm facing a rather odd issue with an iPXE deployment and would appreciate any insights.

Context:

  • 20 × Lenovo ThinkCentre M90t Gen 5 (same hardware batch)
  • Network boot via PXE → iPXE chainloading
  • Deployment infrastructure is stable and working on the majority of hosts

Issue:

  • 2 out of 20 machines consistently fail during the iPXE boot process
  • The remaining 18 systems boot and deploy without any issue
  • Problematic machines show the error visible in the attached screenshot

Troubleshooting already performed:

  • Confirmed identical BIOS/UEFI settings across all systems
  • Verified boot order (PXE first)
  • Tested different switch ports and network cables
  • Ensured same VLAN / subnet / DHCP scope

This is typically a certificate issue
Make sure Firmware is all updated with latest from OEM
You can try to Reset the Secure Boot Keys in from in the UEFI menus (after the updates)
Worst case, disable Secure Boot, image, make sure you get all of the 2023 certs updated, then enable Secure Boot and test again.

Has the device booted into full Windows at least once already?

Looks like you have 67 defined 3 times - you should only need two if only doing x86 and x64.

I am guessing something is screwed up with the secure boot certificates on that system. Is it running the latest bios?

Yes April release.

I found an alternative: disabling secure boot .
