Having very difficult recovering my system

General system Kernel, boot, graphics & hardware
1

Well I was playing around and deleted both kernels I had (my mistake).

Anyway, I have live USB and I have been trying to chroot into my system, and every time I get the error message

/mnt/boot/efi: mount point does not exist.

This applies also if I do /mnt but I do have a EFI system so /mnt/boot/efi should apply.

I am going through these instructions https://discovery.endeavouros.com/system-rescue/arch-chroot-for-efi-uefi-systems/2021/03/

I am using BTRFS so I went after the tutorial about that, and here is the result of that

[liveuser@eos-2022.09.10 ~]$ sudo btrfs subvolume list -p /mnt

Then I decided to install Timeshift to my live user, because I literally have a working snapshot from midnight.
However I can’t install Timeshift, all of the dependencies get timed out due to connection error, like I am not connected to the internet at all.

I am however writing from the live user and I am connected to Wi-Fi.
I do feel a bit lost at the moment and good ideas would be appreciated.

sudo mount -o subvol=@ /dev/nvme0n1p1 /mnt
sudo mount  /dev/nvme0n1p0 /mnt/boot/efi
sudo arch-chroot /mnt

From the chroot:

pacman -S linux linux-headers

Thank you for the reply, unfortunately I still can’t chroot, I copied/paste your commands

[liveuser@eos-2022.09.10 ~]$ sudo mount -o subvol=@ /dev/nvme0n1p1 /mnt
mount: /mnt: wrong fs type, bad option, bad superblock on /dev/nvme0n1p1, missing codepage or helper program, or other error.
       dmesg(1) may have more information after failed mount system call.
[liveuser@eos-2022.09.10 ~]$ sudo mount  /dev/nvme0n1p0 /mnt/boot/efi
mount: /mnt/boot/efi: mount point does not exist.
       dmesg(1) may have more information after failed mount system call.

Can we see lsblk -o name,type,fstype,size

lsblk -o name,type,fstype,size

You need this:

sudo mount -o subvol=@ /dev/nvme0n1p2 /mnt
sudo mount  /dev/nvme0n1p1 /mnt/boot/efi
sudo arch-chroot /mnt

From the chroot:

pacman -S linux linux-headers

This is interesting…

sudo mount  /dev/nvme0n1p1 /mnt/boot/efi
mount: /mnt/boot/efi: mount point does not exist.

What does ls /mnt show?

10 
ls /mnt
@  @cache  @home  @log  timeshift-btrfs
11

You did the first command wrong. Try again, unmounting /mnt first.

sudo umount /mnt
sudo mount -o subvol=@ /dev/nvme0n1p2 /mnt
sudo mount  /dev/nvme0n1p1 /mnt/boot/efi
sudo arch-chroot /mnt
