Hello there, I'm facing a problem with syslinux in a windows WDS environment: I run syslinux since several years like this: https://wiki.syslinux.org/wiki/index.php?title=WDSLINUX Since modern computers usually boot up with EFI I recently wanted to add EFI support to my WDS-syslinux environment, but it doesn't work: https://www.d7xtech.com/tech-info/network-boot-guide/install-syslinux-on-wds/ For this I copied syslinux.efi (from Debian bullseye) to the WDS-Server and tried to "activate" it: wdsutil /set-server /bootprogram:boot\x64\syslinux.efi /architecture:x64UEFI wdsutil /set-server /N12bootprogram:boot\x64\syslinux.efi /architecture:x64UEFI All other files are left unchanged, so the legacy installations work normaly. Now my UEFI-boot-client just tells me about an error during "Windows Deployment System", error 0xc000026c Can anyone help me to get UEFI work with WDS? Thank you Christian
