 Posted: Fri Feb 16, 2024 6:18 am Post subject: Updated grub and now system is dead [SOLVED] |
 |
|
I did emerge -uDN @world. One of the packages updated was grub from 2.12 to 2.12-r1. After the update, before rebooting, I ran grub-mkconfig; probably not necessary, but it doesn't hurt -- or does it? After restarting, the BIOS splash screen flashes for a half a second and drops me in the BIOS setup screen. I didn't do much in the BIOS config -- I don't think, but it still doesn't boot at all.
When I was in the BIOS setup screen the first time I think I had to choose EFI or grub. I ignorantly chose grub. It didn't help.
Any suggestions other than wipe everything and reinstall? I was thinking of running grub-install, if I can get access to it booting from a live USB stick. My system is an AMD Ryzen 5000 series
with Aorus BIOS. Please help.

I think you'll never need to reinstall, unless that is what you want. Just chroot into your installation and try to configure your grub again. Make sure your /boot or /efi is mounted and run grub-mkconfig -o /(path to)/grub/grub.conf or something similar.

What happens if you choose EFI instead?
Other option is boot your kernel via UEFI. I don't know why, but recently I've seen a lot of people having problems grub here in the forums. I really don't know why, because in my mind grub is supposed to be something that just works. (??)
You can try fix your grub, if it goes wrong you can try boot your kernel via UEFI. Here is a tutorial if it interests you.

had similar problem, although it went gave 'grub_is_shim_lock_enabled' not found. had to chroot and downgrade grub to earlier sys-boot/grub-2.06-r9
[rant]
I have had lots of trouble with UEFI and the Gentoo guides about it are so hard to follow in my opinion. I have very very old system and I would need to delete ESP and create it and create keys, sign and enroll keys, there really should be some easy guide besides working gentoo-kernel and installkernel wich I don't use, I use gentoo-sources and manual install .. Maybe I have to reconsider this... I'm becoming lazy :D
I'm running my bios (Gigabyte AX370M-DS3H) now in setup mode and if only there would be easier way to make this work safe/secure way it would be good. Year ago I did some mistake and managed to brick my bios doing these secure boot/efibootmgr tricks, I had to hardware flash it(I used arch and flashrom with cheap chinese ch341 usb stick), luckily that worked out and I did think that I don't mess with bios/efi anymore! It was hell.... Here we go again... [/rant]

| there is a news item saying that it is necessary to re-run 'grub-install' and 'grub-mkconfig' after a grub update, see https://bugs.gentoo.org/920708 |

Same error here. This workaround fixed it. Just booting minimal gentoo install, mount stuff, chroot, mask 2.12-r1, now remerge 2.06-r9, run grub-mkconfig -o /boot/grub/grub.cfg and it is working again |

Thank you tremendously! You saved me. One thing I had to do was use this line in grub-install:
| Code: | | (chroot) > grub-install --target=x86_64-efi --efi-directory=/boot --removable |
Found it on this page

| For me it worked without the "--removeable" parameter. |

| I would think it depends on your BIOS. |

| The option "--removable" installs the grub binary to the ESP under "\EFI\BOOT\BOOTX64.EFI". If you have another bootloader installed, it is possible that the other bootloader will overwrite "\EFI\BOOT\BOOTX64.EFI" with its own binary. |

Always good to have a rescue Linux on a bootable USB drive at hand. Additionally I now also prepared a script with the steps from the chroot how-to as `/chrootThis.sh` (am I reinventing the wheel here?).
| Code: |
#!/bin/sh
# Prepare and mount this filesystem with chroot.
# Current working directory must be the location of this script.
set -e
mount --rbind /dev dev
mount --make-rslave dev
mount -t proc /proc proc
mount --rbind /sys sys
mount --make-rslave sys
mount --rbind /tmp tmp
mount --bind /run run
cp /etc/resolv.conf etc
echo "Execute this:"
echo ". /etc/profile"
echo 'export PS1="(chroot) $PS1"'
chroot . /bin/bash

 Well maybe. I had the exact same idea after experiencing this same problem a day or two ago. So i made a chroot script to save myself from typing a whole lot of commands. |
