[Bug 1899308] Re: failure to boot groovy daily (again)

[Thomas Schmitt]

Hi,

> You are a wizard Thomas,

I lurk at boot loader mailing lists since more than a decade.

But as sysadmin i am lame enough to not knowing how to make ASUS ProWS
C246-ACE EFI firmware 1401 offer me any external storage device for
booting, or how to disable its Secure Boot setting.
I will have to ask the provider of the machine how he installed a
Debian 10 base system to it a few months ago.

(It will be my next workstation. But due to some hardware flaws i began
to use it for kernel experiments. Now the flaws are gone and i should
invest more time into accomodating it to my oldfashioned window manager
desires.)

That means we should ask Steve Langasek to add option

  --mbr-force-bootable

to the xorriso -as mkisofs command that is used for ISO production.

Then the waiting for complaints will begin again.

That would mean to revive ISOLINUX as BIOS boot loader.
I assume there were compelling reasons to switch to GRUB for that job.

(My current theory for Lenovo V130 is that its firmware recognizes
ISOLINUX isohybrid and then drops its usual demand for valid GPT.
The V14 could have the flaw that it offers to disable Secure Boot but
nevertheless fails if no Secure Boot signature is found.
I am not aware that we got confirmation that V14 boots with old Ubuntu
ISOs. We have a report in #176 of 1886148 that Manjaro and openSUSE fail.)

Have a nice day :)

Thomas

Title:
  failure to boot groovy daily  (again)

Status in Ubuntu CD Images:
  New
Status in cd-boot-images-amd64 package in Ubuntu:
  Confirmed

Bug description:
  This is either a duplicate or return of
  - https://bugs.launchpad.net/ubuntu-cdimage/+bug/1883040
  - https://bugs.launchpad.net/ubuntu-cdimage/+bug/1886148

  Most probably "groovy daily won't boot anymore on some older BIOS
  boxes" or the 1883040 bug, as it's impacting only my older slow boxes
  (but it's also different).

  thumb-drive has been successfully used in QA live & install tests,
  however it won't boot on

  hp dc7700 (c2d-e6320, 5gb, nvidia quadro nvs 290)
  hp dc7900 (c2d-e8400, 4gb, intel 4 series integrated i915)

  The last timing issue also impacted d755-5 (older dell optiplex 755)
  when dc7700 was impacted, but that booted successfully this ISO.

  I see thumb-drive flash as it tries to boot, eventually it stops
  flashing, but no boot. At least 6 attempts made to boot, thumb-drive
  being tested on another 2x d755 boxes..

  (ISO written by mkusb/dus & gnome-disks [#11] is identical)

  ** Expected result

  It boots & is usable
