[Solved] Uncertain if grub is configured correctly. | Arch Linux Community | Page 1

#

I'm currently installing archlinux to dual boot with windows 10. My windows install is bios install (disk is dos label). I installed grub, os-prober and enabled os-prober to search for other systems in the appropriate file.
When I ran the mkconfig for grub, grub detected:
linux image
initrd image
warning that os-prober is enabled and will look for other systems.
Added boot menu entry for UEFI Firmware Settings (I assume my motherboard)
Done

So I was expecting it to detect my mounted windows 10 system drive as well. Any idea why it is not detecting it and how I can fix that?

That has nothing to do with dual boot

#

did u mount them during the arch install process?

long wave Nov 3, 2022, 10:05 PM

#

yes

still hornet Nov 3, 2022, 10:06 PM

#

cat /etc/fstab

long wave Nov 3, 2022, 10:06 PM

#

I just used lsblk again and it is mounted to /windows10

#

ok will run that

#

I have 3 filesystems there

#

the main linux one mounted to /
the win one mounted to /windows10
and the swap one

still hornet Nov 3, 2022, 10:08 PM

#

so the text in that file tells linux what partitions to mmount where on boot

#

show me the output

fossil scaffold Nov 3, 2022, 10:08 PM

#

i encountered that problem as well

still hornet Nov 3, 2022, 10:08 PM

.s rs

still hornet .s rs

fossil scaffold Nov 3, 2022, 10:08 PM

#

the SOLUTION was

#

to boot from hard disk on your installed arch machine

#

instead of the current live usb

#

and then redo the

#

grub-mkconfig

long wave Nov 3, 2022, 10:09 PM

#

ok so should I reboot and then redo the config to allow me to boot into windows as well

#

I will try that

fossil scaffold Nov 3, 2022, 10:09 PM

#

yeah from hard disk

long wave Nov 3, 2022, 10:09 PM

#

still hornet .s rs

not sure what this is

fossil scaffold Nov 3, 2022, 10:10 PM

#

its basically

#

pastebin

#

but from the command line

long wave Nov 3, 2022, 10:12 PM

#

oh ok, I will do that after I try booting from the harddrive

#

unfortunately, I while trying to boot from the harddrive I encountered another problem, I'm stuck at Loading initial ramdisk now

fossil scaffold Nov 3, 2022, 10:23 PM

#

did you generate your fstab properly

#

you can try and continue off where you last left off

#

by using the live usb once again

#

and use lsblk

#

to see your partitions

#

then mount then like when you first made them to /mnt

long wave Nov 3, 2022, 10:24 PM

#

can I just power it off with the button?

fossil scaffold Nov 3, 2022, 10:24 PM

#

yes

#

it shouldnt break anything

#

if you force shutdown it

long wave Nov 3, 2022, 10:28 PM

#

should I generate the fstab again

#

it seems like it was before

#

I guess I need to find how to use the .s rs command to print the result

fossil scaffold Nov 3, 2022, 10:32 PM

#

did you

#

mount your stuff ?

long wave Nov 3, 2022, 10:32 PM

long wave Nov 3, 2022, 10:32 PM

#

fossil scaffold mount your stuff ?

yes

#

# See fstab(5) for details.

#

did you install the linux package?

long wave Nov 3, 2022, 10:34 PM

#

yes

#

oh but I think there could have been an issue with it

#

I remember it was telling me that packages were empty

fossil scaffold Nov 3, 2022, 10:34 PM

#

the initial ramdisk is made

#

by the linux package hook

#

try and reinstall the linux package

long wave Nov 3, 2022, 10:35 PM

#

like some file with package extension contained no packages

#

ok

#

do I just call the same command I did before

fossil scaffold Nov 3, 2022, 10:35 PM

#

are you in the chroot?

#

or are you outside

#

(chroot is arch-chroot)

long wave Nov 3, 2022, 10:36 PM

#

outside currently

fossil scaffold Nov 3, 2022, 10:36 PM

#

chroot in

#

arch-chroot /mnt/blahblah

long wave Nov 3, 2022, 10:36 PM

#

done

fossil scaffold Nov 3, 2022, 10:36 PM

#

does the pwd command work

long wave Nov 3, 2022, 10:37 PM

#

when I type pwd

#

I get /

fossil scaffold Nov 3, 2022, 10:37 PM

#

thats good

#

see if you have internet

#

ping archlinux.org

#

there should be results

#

#

ctrl + c to stop pinging

long wave Nov 3, 2022, 10:37 PM

#

getting everything

fossil scaffold Nov 3, 2022, 10:38 PM

#

alright

#

now try and reinstall the linux package now

#

sudo pacman -Syu linux

long wave Nov 3, 2022, 10:38 PM

#

oof I pressed the windows key and I can't type anymore

#

it happened to me before as well

fossil scaffold Nov 3, 2022, 10:38 PM

#

💀

long wave Nov 3, 2022, 10:39 PM

#

is that normal?

#

ok somehow fixed it

#

I had to press ctrl+win+c and it got fixed, dunno if that has happened to others

#

so it reinstalled

#

here the same warning as before

fossil scaffold Nov 3, 2022, 10:40 PM

#

show the warning

long wave Nov 3, 2022, 10:41 PM

#

present file '/etc/mkinitcpio.d/linux.preset' is empty or does not contain any presents

#

that is the warning

fossil scaffold Nov 3, 2022, 10:43 PM

#

do

#

sudo rm /etc/mkinitcpio.d/linux.preset

#

and redo'

#

sudo pacman -Syu linux

long wave Nov 3, 2022, 10:45 PM

#

ok that error is no longer there

#

I have other errors

fossil scaffold Nov 3, 2022, 10:45 PM

#

what are the other errors

long wave Nov 3, 2022, 10:45 PM

#

possible missing firmware "same name"

fossil scaffold Nov 3, 2022, 10:45 PM

#

for that

#

you'll need to install

#

linux-firmware

#

its basically the drivers

#

for most of your stuff

long wave Nov 3, 2022, 10:45 PM

#

xhci_pci

#

qed

fossil scaffold Nov 3, 2022, 10:46 PM

#

oh

long wave Nov 3, 2022, 10:46 PM

#

wd719x

fossil scaffold Nov 3, 2022, 10:46 PM

#

thats just generating the

#

ramdisk

#

those are harmless

long wave Nov 3, 2022, 10:46 PM

#

oh ok

#

I did install linux-firmware before, but I guess better reinstall again

fossil scaffold Nov 3, 2022, 10:47 PM

#

you can if you want to

#

sudo pacman -S linux-firmware linux

long wave Nov 3, 2022, 10:47 PM

#

did it it was fast

fossil scaffold Nov 3, 2022, 10:47 PM

#

the "errors" your receiving

#

https://wiki.archlinux.org/title/Mkinitcpio

Mkinitcpio

#

section 5.4 has the fix

long wave Nov 3, 2022, 10:47 PM

#

thank you

fossil scaffold Nov 3, 2022, 10:47 PM

#

but its really a cosmetic issue

#

so you can skip it for now

long wave Nov 3, 2022, 10:47 PM

#

ok do I have to redo everything I've done so far from the moment I installed linux

#

or is grub and everything still installed?

fossil scaffold Nov 3, 2022, 10:48 PM

#

grub and everything should still be stilled

#

installed*

#

you can check

long wave Nov 3, 2022, 10:48 PM

#

ok so should I just reboot

fossil scaffold Nov 3, 2022, 10:48 PM

#

not yet

#

can you show the dirs of /

#

ls /

long wave Nov 3, 2022, 10:48 PM

#

bin boot

#

dev

#

etc

fossil scaffold Nov 3, 2022, 10:48 PM

#

ok yeah

long wave Nov 3, 2022, 10:48 PM

#

home

fossil scaffold Nov 3, 2022, 10:48 PM

#

cd /boot

long wave Nov 3, 2022, 10:48 PM

#

lib

fossil scaffold Nov 3, 2022, 10:49 PM

#

cd /boot

#

and then run ls

long wave Nov 3, 2022, 10:49 PM

#

yeah I'm there

fossil scaffold Nov 3, 2022, 10:49 PM

#

and show the result

long wave Nov 3, 2022, 10:49 PM

#

amd ucode

#

grub

#

initramfs linux fallback img

fossil scaffold Nov 3, 2022, 10:49 PM

#

vmlinuz

#

too?

long wave Nov 3, 2022, 10:49 PM

#

the ucode is also img

#

yes

fossil scaffold Nov 3, 2022, 10:49 PM

#

initramfs is your initial ram disk btw

long wave Nov 3, 2022, 10:49 PM

#

and initramfs linux without fallback

fossil scaffold Nov 3, 2022, 10:50 PM

#

okay then

#

you should

#

redo grub-mkconfig

long wave Nov 3, 2022, 10:50 PM

#

ok

fossil scaffold Nov 3, 2022, 10:50 PM

#

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

#

after its done you can exit out of the chroot

#

exit

#

unmount everything umount -a

long wave Nov 3, 2022, 10:51 PM

#

wait I need to go back to the base directory too right

fossil scaffold Nov 3, 2022, 10:51 PM

#

and then reboot to hardddisk

long wave Nov 3, 2022, 10:51 PM

#

I was in boot

fossil scaffold Nov 3, 2022, 10:51 PM

#

it shouldnt matter

#

what did the

fossil scaffold Nov 3, 2022, 10:51 PM

#

fossil scaffold `sudo grub-mkconfig -o /boot/grub/grub.cfg`

what did this command say

long wave Nov 3, 2022, 10:52 PM

#

ok it found the same stuff as before without the win dir, I will do the reboot now

#

basically it found amd ucode

#

vmlinuz linux

#

found initrd

fossil scaffold Nov 3, 2022, 10:53 PM

#

alright

long wave Nov 3, 2022, 10:53 PM

#

found fallback initrd

fossil scaffold Nov 3, 2022, 10:53 PM

#

reboot and pray it gets past the initial ramdisk

#

tux 🙏

long wave Nov 3, 2022, 10:53 PM

#

instead of reboot can I do poweroff

fossil scaffold Nov 3, 2022, 10:54 PM

#

sure you can

long wave Nov 3, 2022, 10:54 PM

#

and then remove the flash and boot

fossil scaffold Nov 3, 2022, 10:54 PM

#

👍

long wave Nov 3, 2022, 10:54 PM

#

I got to the login this time

#

ok I'm in

#

time to redo the config right

#

the mnt are still correct

fossil scaffold Nov 3, 2022, 10:56 PM

#

alright

#

you should do

#

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

#

and it should detect windows

long wave Nov 3, 2022, 10:58 PM

#

it did

#

nice

#

thanks alot folks!

#

both for the help, and also because I learned a lot!

fossil scaffold Nov 3, 2022, 10:59 PM

#

alright

#

when you reboot you should see the option now

long wave Nov 3, 2022, 11:00 PM

#

could I ask one final question before closing this threat? Should I do the microcode commands now that grub is installed and everything is ready

fossil scaffold Nov 3, 2022, 11:00 PM

#

i believe grub already detected your microcode packages

long wave Nov 3, 2022, 11:00 PM

#

ah I see

#

thanks

#

I will reboot now just to see if I can go back to windows

fossil scaffold Nov 3, 2022, 11:00 PM

#

if it says

fossil scaffold Nov 3, 2022, 11:01 PM

#

long wave basically it found amd ucode

r

#

then it should be automatically added if grub-mkconfig says that

long wave Nov 3, 2022, 11:01 PM

#

I see

#

ok time to reboot

#

wooohooo I can boot back to windows as well now, time to finish the linux install.

#

thanks again I will make this thread solved now
