so i have to admit this was my fault, was playing around with the GRUB customizer, don’t really understand what happened aha but when i rebooted my system all my menu entries are gone.
i tried this solution but it didnt seem to work
everytime i tried the arch-chroot command it just came back with this error:
arch-chroot /mnt
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
https://discovery.endeavouros.com/system-rescue/arch-chroot-for-efi-uefi-systems/2021/03/
Edit: For btrfs there are instructions also on the same wiki page
getting this error
sudo mount -o subvol=@home /dev/nvme0n1p1 /mnt/home
mount: /mnt/home: mount point does not exist.
dmesg(1) may have more information after failed mount system call.
should i just go into the mnt folder and create that dir
i would also like to apologies i i didn’t see this article in the OP i have dyslexia so i skim over things sometimes haha
i also forgot to mention i am using the same file system as the OP as well
okay i follow everything, for the home file i just created it
when i tried to run arch-chroot again it just gave me the same error as before
[root@EndeavourOS ~]# arch-chroot /mnt
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
[root@EndeavourOS ~]#
edit: arch-chroot failed so i just used sudo chroot /mnt and that seemed to work
after all of that it still does not work, i tried to run
sudo grub-mkconfig -o /boot/grub/grub.cfg
it just came back with this
/usr/bin/grub-mkconfig: line 52: /usr/share/grub/grub-mkconfig_lib: No such file or directory
at a loss now, no idea how to move on and sort this. any one have any suggestions or should i just fresh install
You are not following the information properly.
sudo lsblk -f
nvme0n1

sudo mount /dev/nvme0n1p1 /mnt
Edit:
Then post output of this command
sudo btrfs subvolume list -p /mnt
[liveuser@eos-2022.09.10 ~]$ sudo mount /dev/nvme0n1p1 /mnt
[liveuser@eos-2022.09.10 ~]$ sudo btrfs subvolume list -p /mnt

sudo umount /mnt
sudo mount -o subvol=@ /dev/nvme0n1p1 /mnt
sudo mount -o subvol=@log /dev/nvme0n1p1 /mnt/var/log
sudo mount -o subvol=@cache /dev/nvme0n1p1 /mnt/var/cache
sudo mount -o subvol=@home /dev/nvme0n1p1 /mnt/home
sudo mount /dev/nvme0n1p6 /mnt/boot/efi
Then
sudo arch-chroot /mnt
Edit: I hope i got this right as I’m not an expert but i do use btrfs also.
So then try to update grub if you get no errors.
I’m not sure what is on /dev/nvme0n1p2?
i’m sure this is what i done to the T, but ill give it another shot and see if it works, if it doesn’t should i just fresh install?
If you did it following the wiki then it would be working so i doubt it.
had a look on gparted and it said its a Microsoft reserved partition? i
Okay… that’s fine.
Edit: We are only concerned with the linux set up and the efi partition in order to arch-chroot.
Nope

You spelled it wrong. Commands have to be accurate.
[liveuser@eos-2022.09.10 ~]$ sudo mount /dev/nvme0n1p6 /mnt/boot/efi
i did
Okay i see you entered it again.
