PXE boot to install linux OS in UEFI

[lebrun78]

Hello,
I have a kernel panic problem when I try to install linux OS using ipxe in UEFI mode.
I have not problem to install using ipxe boot in legacy mode or to point my MDT server.

Should I have differents entries for UEFI ?
Which parameter should I modify ?

Here is my Advanced Menu settings

:MENU
menu
item --gap -- ---------------- iPXE boot menu ----------------
item Centos7 Install mini Centos7
item Centos8 Installation Centos8
item Ubuntu20 Installation Ubuntu20
item WIN10MDT1903 Boot MDT-Win10-1903
item shell ipxe shell
item return return to previous menu
choose --default WIN10MDT1903 --timeout 10000 target && goto ${target}

Thank you for your help.

Based on my experience your kernel arguments are not complete.

Based in the error message I would say your initrd file is not compatible with your kernel.
