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 _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org https://lists.gnu.org/mailman/listinfo/grub-devel
