So if we want to propose a workaround for the current layout, it would be a good base if you could confirm that j3400 boots after the plain procedure with no other experiments inbetween:

  # Patch the ISO already as image on hard disk
  ISO=ubuntu-22.04-desktop-amd64.iso
  dd if=/dev/zero bs=1 count=16 of="$ISO" conv=notrunc seek=462

  # Put it onto the USB stick as you usually do. E.g.
  sudo dd bs=4M oflag=sync status=progress of=/dev/sdb if="$ISO"

Then you would check if it boots twice on the j3400. If the second boot
succeeds and shows a writable big partition as last one, then we could
be sure that this procedure is a valid workaround.

A run of

  sudo xorriso -indev stdio:/dev/sdb -report_system_area plain

would (hopefully) confirm that there is no second MBR partition with
boot flag.

Of course it would be enough if you can confirm that you did this already during the experiments, with no intermediate manipulations. But given the curvy way of this bug report, we need to be sure.

I grabbed my thumb-drive 2; Ubuntu-MATE jammy (2022-04-19)
- plugged into j3400; enter pressed [just] @12:28 using room clock, plymouth seen at 12:36, maybe-ubiquity appeared at 12:38

This wasn't required/requested; but I omitted `sudo` for last; so added
here

Ejected thumb-drive (2) & booted on plugged into hp.dc7700; it failed to boot :(

On j3400; pressed ENTER (at grub) at 13:10 (room clock)..  I didn't note
time of plymouth but I had maybe-ubiquity @ 13:13 (room clock) for
altered version of 2022-04-19 ISO

I used SysRq-REISUO to shutdown there..  (I'm reading your instructions as I do it)
so I'll now boot twice (not record times) & shutdown... 

alas should have noted clock.. it 'feels' slow... nah it's slow :(  sysrq-reisub @ maybe-ubiquity.
another boot on j3400, hit ENTER (at grub) at 13:31, maybe-ubiquity jingle waking me from sleep at 13:41.. i hit TRY and let it boot, settle a bit then selected shutdown at GUI.

Thumb-drive plugged back into my primary box; the following is result

Title:
  Impish live session takes ages to boot on BIOS systems

Status in Release Notes for Ubuntu:
  Fix Committed
Status in casper package in Ubuntu:
  Confirmed
Status in casper source package in Impish:
  Confirmed
Status in casper source package in Kinetic:
  Confirmed

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.
