It is. I have now pushed EFI code there. I have regenerated http://people.debian.org/~sthibault/hurd-i386/installer/cdimages/daily/debian-sid-hurd-i386-NETINST-1.iso > xorriso -indev debian-hurd-2019-i386-NETINST-1.iso \ > -report_system_area plain \ > -report_el_torito plain now yields Volume id : 'Debian sid h-i386 n' System area options: 0x00000201 System area summary: MBR protective-msdos-label cyl-align-off ISO image size/512 : 366800 Partition offset : 0 MBR heads per cyl : 64 MBR secs per head : 32 MBR partition table: N Status Type Start Blocks MBR partition : 1 0x80 0xcd 1 366799 El Torito catalog : 703 1 El Torito cat path : /boot/boot.cat El Torito images : N Pltf B Emul Ld_seg Hdpt Ldsiz LBA El Torito boot img : 1 BIOS y none 0x0000 0x00 4 36581 El Torito boot img : 2 UEFI y none 0x0000 0x00 608 53849 El Torito img path : 1 /boot/grub/grub_eltorito El Torito img opts : 1 boot-info-table El Torito img path : 2 /boot/grub/efi.img So there is efi stuff in there, and efi.img does contain bootia32.efi, but kvm -cdrom debian-sid-hurd-i386-NETINST-1.iso -bios OVMF.fd doesn't manage to boot it. Perhaps that's a kvm issue, or perhaps that's a grub-ia32 issue (since I can't boot a linux-i386 image either), do you have an idea at this point? Samuel
