Hmm, that’s odd, it chooses the i386 BIOS variant. This is a x86\_64 image, right?

Can you try to add `--target=x86_64-efi` to the line in `grub.sh` that it mentions? There is a line right below it which is very similar; you should add it there too.

Don’t forget to run `./docker-build` afterwards to rebuild the mender-convert Docker image before trying to convert again.
