[Bug 1922342] Re: HIrsute live session takes ages to boot on BIOS systems

[Chris Guiver]

I'm 'floored' (WOW) by Thomas Schmitt (scdbackup)'s comment 32.

The long delay still exists in impish (on some devices only).

Ubuntu impish - https://bugs.launchpad.net/ubuntu/+source/casper/+bug/1929029
Lubuntu impish - https://bugs.launchpad.net/ubuntu/+source/casper/+bug/1928939 

Delay occurs regardless of ISO being written using mkusb, dd, or gnome-
disks..

It would be nice if something could be shown on screen, the fact that
the OP of this bug report originally wrote that the issue wasn't that it
took ages, but failed to boot - highlights some don't wait long
enough...

I wait 30-60mins in QA-testing & just comment the time in the iso.qa.ubu
report (when I consider excessive), which is longer than I suspect end-
users would expect/accept..

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

Status in casper package in Ubuntu:
  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.
