Grub error after changing default, too fast to read reboots to bios

Hello there,

I tried to add a theme to GRUB in my /etc/default/grub file that evidently failed as GRUB now displays an error so fast I can't read it then reboots to bios.

I arch-chrooted to my install and rerun

# grub-install --target=i386-pc /dev/sda

and

# grub-mkconfig -o /boot/grub/grub.cfg

after commenting changes in default file.

What can I do from now ?

Thank you.

It appears to be

error: file '/boot/grub/locale/C.gmo' not found.

What's your output of

locale
locale -a

before running the GRUB commands

You probably want to set that to something sensible  before running grub-install/mkconfig https://wiki.archlinux.org/title/Locale … the_locale and https://wiki.archlinux.org/title/Locale … _immediate

Hi, I'm coming back here with new motivation to solve the issue, but I don't understand what you mean by setting locale to something "sensible".

Furthermore I tried booting through rEFInd but it drops to rescue shell because of a '' filesystem not found.

To an actual locale rather than C like en_US.utf8 or fr_FR.utf8 you are using C according to these outputs

Re: Grub error after changing default, too fast to read reboots to bios

It's weird, I did regenerate my locale with locale-gen after editing locale.conf to look like this :

LANG=fr_FR.UTF-8
LANGUAGE=fr_FR:en_US:en:C

and with the correct locales uncommented in locale.gen
but locale still outputs everything C.UTF-8

Re: Grub error after changing default, too fast to read reboots to bios

did you uncomment the appropriate line in /etc/locale.gen?
