Grub don't show any other things

Jwdev · 2021-03-18 08:30:38

Hi, I must specify the first, my English is not well. So please talk a little simpler.

My problem is Grub not shows me anything outside the my arch. (Used to have another operating system and i did not see it and now i don't see any GNU/Linux Distro in my flash even it's arch.)

My computer is not supporting UEFI, so i have a legacy bios, i tried to understand arch wiki but i could not.

Have you re-made grub.cfg? If yes, check /etc/default/grub and look for:

GRUB_DISABLE_OS_PROBER="true"

Change "true" to "false" and re-do:

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

See if that helps.

No, i don't. I looked my default grub config and I don't have such a setting. Should I add?

What's your disk layout?

sudo fdisk -l

And the contents of grub.cfg?

cat /boot/grub/grub.cfg

Okay.

Perhaps an obvious question, but do you have the package os-prober installed?
If not, install it, then re-run

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

as root or

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

as a normal user.

I already installaed os-prober, and i use this command soo much times before.

Did you remember to mount the partition(s) that contain the other operating system(s) before running the grub-mkconfig command?

I tried for my usb (It has a fresh arch iso). But i don't know which one i need mount, so i tried all of them

$ sudo mount /dev/(sdb/sdb1/sdb2/sdb3) /mnt (I made each individually separately.)
$ sudo grub-mkconfig -o /boot/grub/grub.cfg

Is there anything I do wrong?

Mount the root partition under /mnt and mount the /boot partition under /mnt/boot afterwards if there is a separate /boot partition.

What does "I made each individually separately" mean, exactly? What were the *exact* commands that you used? Please post them all verbatim.

If you ran this

# mount /dev/sdb /mnt
# mount /dev/sdb1 /mnt
# mount /dev/sdb2 /mnt
# mount /dev/sdb3 /mnt

Then each command would overlay the partition so only the last one would reflect the contents of /mnt.

I have done it as follows,

sudo mount /dev/sdb1 /mnt
sudo grub-mkconfig -o /boot/grub/grub.cfg

Then i rebooted and it's not working, after i did each for sdb2.

I can't understand english very well, I need to do that?

sudo mount /dev/sdb /mnt/boot

in addition is there no root partition I see in sdb partition. It looks like this.

sdb      8:16   1  14.3G  0 disk
├─sdb1   8:17   1   634M  0 part
├─sdb2   8:18   1    61M  0 part
└─sdb3   8:19   1   300K  0 part

It's not an operating system in installed other disk. It's a live iso for arch linux. So i don't know what is root partition or anything.

I think you must have wiped the operating system on /dev/sdb — 634MiB (sdb1) isn't enough room for an entire distribution, sdb2 is an EFI system partition and sdb3 seems to be a Windows partition.

https://ibb.co/D4NW2jw It looks like this in gui file manager.

That picture shows the Arch live ISO image.

u666sa · 2021-03-20 10:30:55

Be sure to install os-prober

Head_on_a_Stick · 2021-03-20 10:41:57

The OP already has os-prober installed. Please read the thread before replying.

I suspect they are trying to generate a menu entry for the ISO image but the language barrier is confusing things.

@OP: if you do want a menu entry for the live image then see https://wiki.archlinux.org/index.php/Mu … ly_release (place the stanza at the end of /etc/grub.d/40_custom and run the grub-mkconfig command to add it to the menu).
