Well, then the hope to find a simple explanation from tweak 3 was an
illusion.

I am staring at the /boot/grub/grub.cfg of ubuntu-22.04-desktop-amd64.iso
and compare it with Chris Guiver's comment #90:

So i assume that /boot/grub/grub.cfg was executed. But then would last very
long to get from
        linux   /casper/vmlinuz file=/cdrom/preseed/ubuntu.seed maybe-ubiquity quiet splash ---
        initrd  /casper/initrd
to a usable system.

Do i look at the wrong ISO ?
(I could not find Ubuntu "live" ISOs in the web.)

Have a nice day :)

Bug description:
  First of all, I change the description of this bug because, thanks to
  Chris Guiver comments, I could check that the live session effectively
  works but it takes too long to complete. That's why I change the
  description of the bug from live session does not boot to live session
  takes ages to boot. I hope this is the best approach to this.

  I think the problem is the same as described here:
  https://discourse.ubuntubudgie.org/t/20-10-grub-error-can-t-find-
  command-grub-platform/4292. I can see prior to grub menu, briefly, the
  same error: Error can't find grub_platform. After the solution
  described below, this error is not showed and the system is able to
  boot.

  I try making the live usb using startup disk creator and with gnome-
  disks --> Restore disk image and get the same results.

  The live-usb has a gpt partition table instead of mbr like 20.04 live-
  usb has. That implies, I think, that the first one does not boot on
  BIOS systems and the second does.

  I try the same live-usb on an EFI laptop and it boots perfectly
  (perhaps it takes long time, but more less than in this case.

  If I try the solution described here:
  https://bugs.launchpad.net/ubuntu/+source/casper/+bug/1905491/comments/8
  then it works.
