A thread on grub-bug could need attention

[Thomas Schmitt]

Hi,

i am unhappy about the state of the thread

  http://lists.gnu.org/archive/html/bug-grub/2017-12/msg00010.html
  "HP ProBook x360 11 G1 EE incompatible with grub"

which is about an EFI implementation which SYSLINUX for EFI can operate
from USB stick whereas GRUB from USB stick ends up with black screen.

An allergy of the firmware towards ISO 9660 hybrid images on USB stick
can surely be ruled out by
  http://lists.gnu.org/archive/html/bug-grub/2017-12/msg00022.html
  (The only known production ISO with SYSLINUX for EFI does work)
  http://lists.gnu.org/archive/html/bug-grub/2017-12/msg00024.html
  (A normal distro installation works after replacing GRUB by SYSLINUX)

The bug reporter, Michel Bouissou, seems well apt enough to do experiments.
But i am not apt enough to propose any beyond ISO 9660.
Could people from this list please give Michel some hints about how to
retrieve more information about the problem between GRUB and this
peculiar EFI ?


Have a nice day :)

Thomas
