Well, wasn't expecting this...

I rebooted my laptop, and it keeps booting to the grub shell.

I was going to arch-chroot into it and update grub, and rebuild intarimfs, however, I guess I don't know how to with BTRFS subvolumes that are LUKS encrypted.

I would appreciate any help, and am willing to learn.

I could even jump on a call of some kind if anyone has time to help...

Arch

BTRFS encrypted with LUKS (No LVM)

GRUB

I live booted into the live usb

cryptsetup luksOpen /dev/nvme0n1p2 arch
mount /dev/mapper/arch /mnt
arch-chroot /mnt

Output:

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

So I browsed /mnt and it lists subvolumes. However, I am not sure how to go about arch-chrooting into this.

I am fully with you!

Thank you! Wish I was the one who figured it out. I am just sharing what was taught to me!

That is exactly the reason I joined Lemmy, to ditch centralization.
