If this ever changes, then i advise to test a grub-mkrescue made ISO. I assume that it has the best chances to get the attention of GRUB developers. > *** Keys booting OK out of the box : > - Tails : tails-amd64-3.2.iso (created by Tails USB installer from > another same version Tails key) > - tails-amd64-3.3.iso : Made by an auto-upgrade of the previous one How are they related to the ISOs offered as e.g. http://dl.amnesia.boum.org/tails/stable/tails-amd64-3.3/tails-amd64-3.3.iso ? Version 3.2 is not to see there, but i have an old 3.1 and now got the 3.3 ISO. Both have no EFI boot equipment but only MBR code for BIOS which hops onto program /isolinux/isolinux.bin in the ISO. Made by an older version of Debian's live-build, as it seems. There is one MBR partition of type 0x17. I wonder what the creation processes do, which you mention. Are the USB sticks still recognized as "ISO 9660" by (/usr/sbin/)file ? Do they have a GPT or a MBR partition of type 0xef ? Have a nice day :) Thomas _______________________________________________ Bug-grub mailing list Bug-grub@gnu.org https://lists.gnu.org/mailman/listinfo/bug-grub
