Yes.
The stick needs the remedy once again after casper created the persistent
partition.

Like a unification of relativity theory and quantum mechanics ?

My apologies again for not remembering the results from one year ago
and wasting everybody's time with my first questions of this year.
Between #94 and #103 i was off track.

I'll wait a few days whether Steve Langasek shows up at this bug report.
If not, i plan to file a new wishlist bug for casper which describes
our findings and proposes the code change as of #115.

I re-re-read this report to list the affected machines:
- a tablet computer "motion computing j3400" of Chris Guiver,
- a Gigabyte H61M-D2H-USB3 mainboard of José Marinho (see also
  https://launchpadlibrarian.net/531427797/lshw.txt),
- (a Gigabyte GA-970A-DS3, BIOS F7a 01/24/2013 of tlk in #91, of which we
   have no confirmation that removing MBR partition 2 really helps).

Have a nice day :)

Thomas

  Impish live session takes ages to boot on BIOS systems

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.
