Manjaro is not showing in grub

aquatic7 · Feb 19, 2021

My manjaro dist wouldn’t update and couldn’t find the mirrors.
I followed some tutorials from google to fix it but now I’ve made it even worse.
Only memtest86 was starting on boot.
It seemed that grub didn’t exist no more.
I have now followed tutorials to get grub back, but Manjaro is not showing in grub.
I only have a simple command line grub when booting.

I’ve also tried to delete the grub folder and do:

manjaro-chroot
mkdir /boot/grub
grub-mkcondig -o /boot/grub/grub.cfg
grub-install /dev/sda

And tried following:

GRUB/Restore the GRUB Bootloader

wiki.manjaro.org

But when I reboot I still only have the bash like grub thingy.

Code:

Bash like grub thing?
Can you give more details please.

Do you mean that when Manjaro boots all you have is a bash shell only?

captain-sensible · Feb 20, 2021

I only have a simple command line grub when booting.

do you mean you see something om booting like like:

Code:

grub >

is there anything else on /dev/sda apart from manjaro.

can you do output of :

Code:

fdisk -l     /dev/sda

this will show disk label type . i think yours is mbr. if you use :

Code:

grub-install /dev/sda     //installs grub 
grub-mkconfig -o /boot/grub/grub.cfg   //creates config files after grub has been installed

to be honest i no nothing of arch or manjaro , since i never got dissatisfied with slackware but on googling updating and mirrors seems to involve : /etc/pacman. d/mirrorlist

Alexzee · Feb 20, 2021

You mispelled mkconfig with mkcondig-

Run:
sudo grub-mkconfig -o /boot/grub/grub.cfg

captain-sensible · Feb 20, 2021

thanks over 34 degrees here , probably i will get even more sloppy since beer pending

Alexzee · Feb 20, 2021

Looking at the output of parted -l OP allocated 232 Gig's for his /ext 4 partition and 8.3 Gig's for his swap.....so it appears that he is using the entire HDD that's 240 GB's.

captain-sensible · Feb 20, 2021

true.

and no efi partition i think

Yup-
It's an Acer Aspire laptop.

The question is: what hosed Grub to give him the dreaded:
grub>

captain-sensible · Feb 20, 2021

lets hope O.P comes back with info/questions

Burak998 · Mar 10, 2021

Code:

grub-install /dev/sda     //installs grub

@captain-sensible wouldn't that install GRUB for x86 architacture?

captain-sensible · Mar 10, 2021

Hi @Burak998 well all i can tell you is my motherboard has UEFI firmware and the cpu is 64 bit ; i'm running slackware so that might be the element that makes all the difference ? from Buntu's etc

But thats the command i used to install grub2. It went fine :

Code:

ls /sys/firmware
acpi  dmi  efi	memmap

it seems to be booting efi , entries are there on the EFI partition.

there are also more specific commands such as:

Code:

#grub-install --target=x86_64-efi --efi-directory=/boot/efi --bootloader-id=grub

Manjaro is not showing in grub
