Well, my son left this morning for the week-end with the machine, and I will fly to India myself before I get a chance to do any further testing. So I'm afraid we'll have to wait for season 2 by early march to see the continuation of the story ;-) Kind regards and thanks again for all your help and suggestions. ॐ -- Michel Bouissou <mic...@bouissou.net> OpenPGP ID 0xEB04D09C ___ Grub-devel mailing list Grub-devel@gnu.org https://lists.gnu.org/mailman/listinfo/grub-devel

I made it (with latest debian-gnome 9.3 live), and tested it OK on *another* machine. But on the machine where the problem is, it does *NOT* boot. It does display the key brand/model (instead of "Windows boot manager") but when selecting it, the punishment is as usual : black screen with cursor, game over. No grub message or output of any kind. ॐ -- Michel Bouissou <mic...@bouissou.net> OpenPGP ID 0xEB04D09C ___ Grub-devel mailing list Grub-devel@gnu.org https://lists.gnu.org/mailman/listinfo/grub-devel

I dimly remember that the machine was 64 bit, i.e. should run > bootx64.efi. I'm happy to report that the USB stick I made today with grub-mkrescue-sed.sh does boot alright on tested machines. As a side note, the machine on wich I made it is a Manjaro that boots in UEFI 64 mode, so for sure it's grub is UEFI-capable. The HP tested machine has, AFAIK, no CSM "legacy" boot mode at all and I believe it doesn't boot anything but UEFI. That said, I don't have the machine on which I made the stick at hand and I made the ISO image in a tmpfs, so...

AFAIR I had tested all the latest (in december) standard installation media for at least : - Manjaro Cinnamon x64 (created either with dd or unetbootin) - Mint Cinnamon x64 (created either with dd or unetbootin) - Ubuntu 17.10 - Debian live - Parted Magic (created with dd) (and maybe a few more, see my first mails...) - Manjaro Cinnamon after it being "normally" installed on a USB key instead of an HD on another machine - and tested working. None of them booted, all showed the same behaviour : - The machine's UEFI BIOS displays the USB Key as « Windows bootloader » (and the true on-HD Windows bootloader bears the same label) - Selecting is causes the screen to go black with a cursor on the top left and nothing else ever happens. Now what works : - rEFInd USB key (made with dd) - Knoppix USB key (made with dd from DVD image) - Tails USB key (both made with dd or from the Tails installer) - Manjaro install key created with unetbootin THEN manually doctored to remove grub and install syslinux instead. - Plus the grub test keys you asked me to create and test in your previous mails. Interestingly, for "working" keys, the machines UEFI displays the USB key brand / model instead of « Windows bootloader » Even more interesting, keys that do NOT work do not work either when chained to from rEFInd (inserting both keys, booting on rEFInd then chaining to the other key), with the same symptoms - where keys that work, also work when performing the same test. As I side note I'm currently packing for a trip to India and will be unable to perform any further tests from next week to the end of february (and will have very little time left for doing so before leaving) Have a nice day :) ॐ -- Michel Bouissou <mic...@bouissou.net> OpenPGP ID 0xEB04D09C ___ Grub-devel mailing list Grub-devel@gnu.org https://lists.gnu.org/mailman/listinfo/grub-devel

It's probably not related to any specific images, as I could boot no standard Linux USB install stick made from an ISO image on this machine, besides Knoppix or Tails. I have installed a Manjaro with grub onto a blank USB stick, in EFI mode, and it would boot perfectly on other machines, but not on affected machine. But AFAIR the USB partition table was DOS, not GPT. So might this machine boot only from GPT disks ? Well, then it would'tn boot a Knoppix ISO image stick. But it does... > Michel: Does a simple ISO "output.iso" work, when made by > > mkdir ./minimal > echo dummy >./minimal/dummy > grub-mkrescue -o output.iso ./minimal > > and then copied onto the plain USB stick device (e.g. /dev/sdc) ? > grub-mkrescue produces valid GPT in ISO 9660. > I've produced an USB stick per your instructions above and tested it OK on another machine.

I tested the USB stick on my son's machine, and I do get a grub prompt. From there, if I type "help", I get a list of grub shell commands. And if I type "reboot", the machine reboots.

I have made a complete Linux install on an USB stick of the latest Manjaro, so the stick is « setup like a hard disk ».

As a side note, this is my son's student machine, he needs it daily in college and also often needs it at home, so I don't have it available all day and I cannot do experiments that would break the installed Windows (alas). I have also been on travel between XMas and january 1st, my son at another place with his machine, and I will be in travel again all february. So I volunteer to perform all necessary tests to understand this issue better, however for the reasons above it may take some time before I can both have the machine at hand and time to work on the issue. But I will try my best to perform all proposed tests - and already did quite a number of them... So far my understanding of the issue is : as soon as the computer loads grub, it freezes, independantly of the distro, used, whether be it from an ISO image or a "normally" installed distro, and whether grub was directly loaded from UEFI, or chained from rEFINd. rEFInd works, Syslinux loads and boots ; grub hangs.
