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

[Chris Guiver]

I'll provide my 2c.

Hirsute (21.04) ISO is already released & development completed.  Only
security fixes are now being performed on the now stable 21.04 system,
which does not include this issue (as this issue relates to the ISO
itself, and re-spins are only done for LTS releases, ie. next ISO will
likely be 20.04.3 or a respin of focal, then impish/21.10 though that's
likely not a complete list)

If this issue matters, I'd test using the impish (21.10) ISO and report
on the QA testing site, even filing a new bug (referencing back to this
one yes, but start a new bug). Even if the report is marked duplicate of
this, it'll increase heat & gain more detail/attention.  This issue was
reported only once on the QA-tracker for hirsute
(http://iso.qa.ubuntu.com/qatracker/reports/bugs/1922342) which
indicates it wasn't a very important issue. Yes I may have included
myself too, had the bug report been about speed, but it was "not
booting" at the time, where my QA-test booted so I didn't link to this.

As for the new installer; the boot process occurs before the installer
is started.  Yes there is a `maybe-ubiquity` kernel parameter but the
system is booted prior to ubiquity running.. so I'd suggest not waiting
for the new installer, but test with `impish` now giving developers the
most time possible to address if they're able.

If you look at testing done so far in 'impish' you'll note well more
than 100 QA-tests have been performed
(http://iso.qa.ubuntu.com/qatracker/reports/testers) so it's not too
early.

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.
