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

[José Marinho]

Hi Thomas,

As I said yesterday, this changes only work at first boot but in the
following boots the behaviour is the same again.

This happened today with the new version of xorriso and yesterday with
"dd if=/dev/zero bs=1 count=16 of="$NEW" conv=notrunc seek=462" command.
On first boot, after dd the ISO file on the stick it boots fine reaching
logo on 25 seconds but after the first boot we have the regression
again.

I'm going to to attach two files (boot1.txt and boot2.txt). The first
one are the output of two xorriso commands BEFORE trying to boot from
the stick, just after dd the iso file on it. The second one (boot2.txt)
is the same but AFTER the first successful boot. The changes on the
output could explain why boots fine only one time.

If it's necessary I append the same command outputs with the iso created
using the dd if=/dev/zero method. These files I append now are from the
iso created using the xorriso method just like you said today morning.

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.
