Hi, I use iVentoy to deploy windows on some machines, but I recently experienced some issues on new firmware. When I select PXE boot in the BIOS iVentoy downloads and then gets stuck and not showing the menu. Originally I used iVentoy version 1.0.21 but also tried 1.0.25 and 1.0.26, this did not make a difference.
I tried different BIOS settings and different boot files to no avail.
The same config and images still work on the older motherboards, and the logs from both are almost identical.
Machine boots successfully
UEFI version 2.22.189 - 2024 AMI
Motherboard: ASUS Pro WS TRX50-SAGE WIFI
Machine boot fails
UEFI version 2.22.1299 - 2026 AMI
Motherboard: ASUS W880-ACE SE
