Grml ISO does not contain syslinux files
The --syslinux flag does not seem to work with Grml 2026.04.

Executing grml2usb version 0.20.13 Using syslinux as bootloader Checking for boot flag Using ISO grml-full-2026.04-amd64.iso Identified grml flavour "grml-full-amd64". Copying files. This might take a while.... ISO does not contain syslinux files (logo.16 not found). Falling back to GRUB for BIOS boot. No /boot/grub/grub.cfg found inside EFI image, looks like Secure Boot support is missing. Skipping syslinux installation, ISO does not support it Synching data (this might take a while)

Indeed. The new ISOs no longer have syslinux at all. Maybe this should have been clearer in the release notes ("BIOS boot uses GRUB2 instead of ISOLINUX" [1]).
grml2usb 0.20.13 has the necessary changes to support GRUB for bios boot, and you can/should drop the --syslinux flag.
Best, Chris
