You are using different grml-live versions. Between grml-live v0.29.7 and v0.30.1 the EFI support for 32bit systems was added as well as switching from isohybrid to xorriso/isohybrid combination. The /boot/efi.img handling is quite tricky overall since it's being generated within a chroot script. This is something I've completely reworked in recent grml-live git for supporting Secure Boot, so the issue you saw with v0.30.1 *might*[1] be fixed already with latest grml-live from git. So if you want just try the latest grml-live version from git, either with the package from https://jenkins.grml.org/job/grml-live-binaries/ or straight out of git: export SCRIPTS_DIRECTORY=$(pwd)/scripts export GRML_FAI_CONFIG=$(pwd)/etc/grml/fai export LIVE_CONF=$(pwd)/etc/grml/grml-live.conf ./grml-live ... [1] "might" because I've not tested your use case and I'm not 100% sure the files required by xorriso/isohybrid are really there as needed regards, -mika-
