Minimal BASH-like GNU GRUB

[bright rover]

Hey, I'm installing Gentoo with musl, in a dual boot with Windows 11 Ghost Spectre.
After installing and configuring grub and os-prober and rebooting, it sends me to the GRUB Minimal BASH-like interface.
What can I do to fix GRUB?

I don't know how to specifically fix your issue, but I way to get into a booting operating system is either chroot from a live USB from an operating system of your choice, or manually boot into your Gentoo install via the grub bash command line.

yeah I managed to boot from grub with that article now :)
but i still need to fix grub, i dont want to type all of that every time i turn my computer on

Yea so, there are a few things that could be wrong.
You mentioned modifying the os-prober setting - did you re-run the command that creates your grub.cfg once you changed os-prober?

[bright rover]

I didn't change anything from os-prober, just installed it and reemerged grub with mount support, wrote GRUB_DISABLE_OS_PROBER=false to /etc/default/grub, and then I ran grub-mkconfig and rebooted

[amber fog]

If you ran mkconfig then I don't see why it would have done that, sorry but this has gone past my knowledge of grub.
I had the same symptom/issue on a non-efi i386 architecture computer when installing Arch with the grub boot loader. I changed the os-prober setting and didnt run mkconfig again

I just did something that made it identify Windows.

• Removed GRUB_DISABLE_OS_PROBER=false from /etc/default/grub
• Ran emerge -avuND @world -- Nothing got changed
• Ran grub-mkconfig -o /boot/grub/grub.cfg -- It identified Windows, but only Windows

Now, I'll take a better look at my fstab

is your kernel present in /boot?

[bright rover]

Yes, I can properly boot with:

grub> set root=(hd0,1)
grub> linux /boot/vmlinuz-3.13.0-29-generic root=/dev/sda1
grub> initrd /boot/initrd.img-3.13.0-29-generic
grub> boot

mmm, actually, doing a ls, it doesn't show the kernel there

;-; but those commands in grub work to boot

[rocky pier]

kernel 3.13

[bright rover]

i just copied from the post

mine isn't that

what I do now? emerge -c and then emerge again?

[rocky pier]

what does ls /boot show?

[bright rover]

grub   lost+found

[rocky pier]

try reinstalling your kernel

first

[bright rover]

Done! Thx @rocky pier
I reemerged grub, os-prober and gentoo-kernel-bin

Everything solved?

[bright rover]
