This is not specific to my Secure boot concerns but, well, I hope some day to integrate Super Grub2 Disk into Debian. Last time I checked Debian I had problems with it because: 4.1. Debian packages do not provide a way of building an hybrid (both valid in i386-pc and efi machines) iso.That's been working for a while now, modulo corner cases like buggy early Intel Macs. I hope you've seen this now!
Sorry for not specifying enough.So, with grub-mkimage (based on grub2's git) you can do an hybrid image that works on:
Hard disk / USB + x86 BIOS Hard disk / USB + UEFI 64bit CDROM + x86 BIOS CDROM / USB + UEFI 64bitLast time I checked the unstable grub2 packages (based on an old grub2 git commit) when trying to do the same hybrid image it only worked on:
Hard disk / USB + x86 BIOS CDROM + x86 BIOS CDROM / USB + UEFI 64bitso that means that it was not able to boot in UEFI 64bit systems from hard disk.
As I think that you would have checked if the four ways of booting works with current debian-cd image I suspect that you using xorriso directly on debian-cd (instead of using grub-mkimage) it's what makes the difference.
