Ventoy Forums

Hello,
I have an issue with iVentoy since version 1.0.35 (which updated iPXE to 2.0.0).
Problem:

• PXE boot gets stuck during iPXE loading on several laptops.
  
• Works perfectly on version 1.0.34.
  
• Same issue on 1.0.35, 1.0.36 and 1.0.37.
  

Affected hardware:

• Lenovo ThinkPad T480 (and several other laptop models)
  
• UEFI mode (Secure Boot disabled)
  

What I already tried:

• Different EFI boot files (snponly.efi, snp.efi, ipxe.efi)
  
• ProxyMode DHCP mode
  
• Secure Boot disabled
  

Result:
Only version 1.0.34 works reliably. Versions 1.0.35+ fail at the iPXE initialization stage.
Note: On 1.0.36 the .XML auto-install scripts also stopped working.
Could you please check the iPXE 2.0.0 integration for compatibility with Intel NICs on ThinkPad laptops?
Thank you!

1. Can you take a photo/screenshot about the client error information?
2. Yes, there is an issue about auto install in 1.0.36, it has been fixed in 1.0.37. refer: https://forums.ventoy.net/showthread.php?tid=3216

Hello,
Here is a screenshot from an HP ProBook 360 11 G1 (the same problem occurs on Lenovo T480 and others) :

The client gets stuck at "Preparing for boot, please wait..."
Additional information:

Works perfectly with 1.0.34
Fails on 1.0.35 / 1.0.36 / 1.0.37 (stuck during iPXE loading)
On 1.0.37 the auto-install (.XML) works only on machines that manage to boot successfully into iVentoy.
It seems to depend on the laptop model and BIOS version (sometimes it works, sometimes not).

I already tried:

Different EFI loaders (snponly.efi, ipxe.efi…)
Lower menu resolution
Secure Boot disabled
External DHCP mode

Thank you!
