Actually I've had this key for a long time. I wasn't expecting to try it on this machine and jus threw it in is despair that nothing else accepted to boot - and I wans't expecting it to. When I created it it was a very old Tails version that has been upgraded since. The process was to boot on the original key (or CDROM) that would be a "temporary" Tails ISO dd'ed, and from there use the “tails installation program" to create a second key, this one being more feature-rich, i.e. with a partition for persistent storage and the possibility to be upgraded over time... So that's this "final" key that I used. It has originally been built from the Tails install program and upgraded many times over years... The key that I use is now : # gdisk -l /dev/sdb [...] Found valid GPT with protective MBR; using GPT. Disk /dev/sdb: 15826944 sectors, 7.5 GiB [...] Number Start (sector) End (sector) Size Code Name 1 2048 5122047 2.4 GiB EF00 Tails 2 5126144 15826910 5.1 GiB 8300 TailsData # file -s /dev/sdb /dev/sdb: DOS/MBR boot sector; partition 1 : ID=0xee, start-CHS (0x0,0,1), end-CHS (0x3ff,254,63), startsector 1, 15826943 sectors # file -s /dev/sdb1 /dev/sdb1: DOS/MBR boot sector, code offset 0x58+2, OEM-ID "SYSLINUX", sectors/cluster 8, Media descriptor 0xf8, sectors/track 62, heads 250, hidden sectors 2048, sectors 5120000 (volumes > 32 MB), FAT (32 bit), sectors/FAT 4991, reserved 0x1, serial number [...],label: "Tails " gparted says that this partition has flags : boot, hidden, legacy_boot, esp (but when copying to other devices I only set flags boot, esp and that's enough) root@zafu:~# file -s /dev/sdb2 /dev/sdb2: LUKS encrypted file, ver 1 [aes, xts-plain64, sha1] So it's a bit far from an ISO9660 filesystem...
