UEFI installation: grub shell after reboot
Hello, I'm trying to install Crux unfortunately with no sucess until now. I installed the UEFI version and there is no success with grub or directly with EFI Stub. After a reboot I get the grub shell. I did the following: I partitionned my hard disk with fdisk. After the partitionning I got: Disk /dev/nvme0n1: 465.8 GiB, 500107862016 bytes, 976773168 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: gpt Disk identifier: 2D20A0A0-716B-4E73-84A4-473759D6509A Device Start End Sectors Size Type /dev/nvme0n1p1 2048 1128447 1126400 550M EFI System /dev/nvme0n1p2 1128448 7419903 6291456 3G Linux swap /dev/nvme0n1p3 7419904 91305983 83886080 40G Linux filesystem /dev/nvme0n1p4 91305984 976773134 885467151 422.2G Linux filesystem I have formatted the first partition "/dev/nvme0n1p1" with ----------------------------------- # mkfs.fat -F 32 /dev/nvme0n1p1 --------------------------------------------- With the setup I have installed grub2-efi and efibootmgr.

did you build nvme support into the kernel? On Mon, Dec 24, 2018 at 6:14 AM Cédric Macquat <banlieue48@mykolab.com> wrote:

What I noticed and don't know:
- when I installed grub, I got a warning that /usr/share/locale doesn't exists. I have created an empty folder.
The /usr/share/locale message is safe to ignore. Just a quick note here - grub-mkconfig will not create a usable config if the kernel is just called "vmlinuz". If you append a version string after it (vmlinuz-4.14 or whatever) it should generate a proper config with fancy menus.
- The grub configuration file "grub.cfg" is not on the same partition as grubx64.efi, because it's in /boot/grub/grub.cfg. Other files for grub are also in that folder. Is it a problem ?
No that's expected.
- I have some doubts, but I changed a few options in the kernel. All options for uefi where compiled in the kernel, not as module. I have also set the command line argument in the kernel with a PARTUUID:
[*] Built-in kernel command line
(root=PARTUUID=55898d79.........e0709) Built-in kernel command string
If you intend to use grub I'd recommend not placing stuff like that in the kernel command-line. I assume the bootloaders arguments would overrule those settings but I'm just guessing as I've never tried it. Keep it simple and just remove that setting.
Do I need to create an initramfs ? All related UEFI options are not compiled as modules. By the way the PARTUUID is the partition of root, not my ESP partition. Finally, the output of efibootmgr: Not for UEFI. From what I can tell you dont need a initrd.

Since you stated you are actually booting into the grub shell, all that should be missing is a proper config. If you rename the kernel from vmlinuz to vmlinuz-<version> and rerun grub-mkconfig it should generate a usable config. /f

It's what I discovered. After renaming it to vmlinuz-4.14.40 grub generated a config file with that entry. Before I had some doubts because it was rather empty. I guess there was no entry in the grub configuration file. That's why I got the grub shell. Everything is fine now, I can boot, thank you! But I have another question: does need somebody to update the installation guide or the users are supposed to know it ? Normally the kernel version is appened to vmlinuz, but nothing more was specified in the installation guide, so I thought it was ok.

I think it's still there, but it boots. I'll remove it as soon as my system will be fully installed.

Yes, it was not necessary. Thank you for your help!
