[SOLVED] Unable to chroot into Arch installation in order to fix GRUB

[half sphinx]

When I booted my Arch system I booted into grub>, I managed to get out of there by using; set pager=1 set root=(hd0,1) linux /vmlinuz-linux-zen initrd /initramfs-linux-zen.img boot

However it booted into the emergency shell.

So I figured the best way to fix it is to fix grub from a live install (EOS). I mounted my flash drive to /mnt and /mnt/boot, which seems to have worked based on the lsblk output. However I get hit with a

mount: /mnt/proc: mount point does not exist.
dmesg(1) may have more information after failed mount system call.
==> ERROR: failed to setup chroot /mnt

I am newb so I am a bit lost in the dark, so I'd appreciate some help with what I should do (I don't even know how to fix GRUB once I chroot into it). Thx

you mounted your usb to /mnt?

you gotta mount your existing arch installation

not the one from your usb

[gleaming summit]

How?

[eager tree]

Could you show us the output of lsblk?

[eager tree]

Yeah you want to mount the drive you have Arch on, not the USB

[half sphinx]

so I do the same command but instead of using sda1 I do nvme0n1p1?

[gleaming summit]

Yes

Ohh

Maybe try mounting 1p2

[gleaming summit]

What file system?

[half sphinx]

btrfs

[gleaming summit]

Ohh

Hmm

/mint/@ should work then

[half sphinx]

that's the system tho

[half sphinx]

doesn't

[half sphinx]

^

[gleaming summit]

Yes?

[half sphinx]

I meant like

that's the normal system

not the EFI

[eager tree]

p1 is your EFI partition, p2 is the one you want to mount first

also make sure you unmount the other partitions first using umount [partition]

[half sphinx]

So what commands should I use?

[eager tree]

First run umount -R /mnt to ensure everything is unmounted

And then, assuming you're using BTRFS subvolumes, run mount /dev/nvme0n1p2 -o subvol=@ /mnt to mount the root subvolume

[half sphinx]

yeah, using the default archinstall subvolume setup, think I got it, now what?

[half sphinx]

anyone?

[eager tree]

You can then chroot using arch-chroot /mnt and then run mount -a in that chroot to mount the rest of your partitions and subvolumes

[half sphinx]

Since they show up doesn't they mean they are already mounted?

[eager tree]

Not sure what you mean by that, but yes they're mounted now

[half sphinx]

so now I can just restart and it will boot?

[eager tree]

No, you haven't done anything to fix GRUB yet

[half sphinx]

oh

[eager tree]

First let's ensure your system is up to date with a pacman -Syu

[half sphinx]

small issue, I use timeshift-autosnap and it won't met let me upgrade

[eager tree]

Could you temporarily disable time shift?

[half sphinx]

I mean, idk how, I wanted to get rid of it for a while but didn't bother to do it ;-; But I can do it now ig

[eager tree]

It might not be necessary to update though, if you don't want to deal with it right now

[half sphinx]

I got rid of it already so

[eager tree]

Alright, then do an update and we can get to fixing GRUB

[half sphinx]

yep, done it, all up to date

[eager tree]

You'll want to run grub-mkconfig -o /boot/grub/grub.cfg to regenerate the GRUB config

[half sphinx]

done

the output if it matters

[eager tree]

Seems good, you can try exiting out of chroot and rebooting now

[half sphinx]

alright

OMGG yess

Ty ty ty

[eager tree]

Good to hear

.n solved
