OK - to avoid confusion, my original aim was to take a syslinux legacy-bios boot cd and add a grub-efi section to it to enable uefi booting. Compared to the mkrescue case, I needed the following: 1. Added iso9660 module to enable grub to read the cd 2. modified grub.cfg with "set root=(cd0)" and (perhaps not required) "set prefix=($root)/EFI/BOOT/grub" Then this worked: $ sudo grub-mkimage --format=x86_64-efi --output=BOOTX64.EFI --prefix=/EFI/BOOT/grub bitmap bitmap_scale boot bufio crypto efi_gop efi_uga extcmd font fshelp gettext gfxmenu gfxterm iso9660 linux loadbios ls minicmd mmap normal part_acorn part_amiga part_apple part_bsd part_dfly part_dvh part_gpt part_msdos part_plan part_sun part_sunpc relocator terminal trig video video_fb $ dd if=/dev/zero of=efiboot.img bs=1K count=1440 $ mkdosfs -F 12 efiboot.img $ sudo mount efiboot.img /tmp/image $ sudo mkdir -p /tmp/image/EFI/BOOT $ sudo cp BOOTX64.EFI /tmp/image/EFI/BOOT $ sudo umount /tmp/image $ sudo cp efiboot.img iso/EFI/BOOT $ sudo mkisofs -pad -l -r -J -V TinyCorePure64 -no-emul-boot -boot-load-size 4 -boot-info-table -b boot/isolinux/isolinux.bin -c boot/isolinux/boot.cat -hide-rr-moved -eltorito-alt-boot -eltorito-platform efi -b EFI/BOOT/efiboot.img -no-emul-boot -o TinyCorePure64_1.iso iso ..and this shaves an additional 2mb, even if I used a 1.44mb image rather than 2.8mb _______________________________________________ Help-grub mailing list [email protected] https://lists.gnu.org/mailman/listinfo/help-grub
