Sudden grub shell with LUKS encrypted partitions

Hi all.

I'm not entirely sure what caused this issue. It happened after update, miraclecast instalation, turning off NetworkManager and wpa-supplicant and turning on wireless deamon from miraclecast.

However I found myself with grub shell on boot. With btrfs and LUKS encrypted partitions (not boot partition) and I'm not really sure what to do to recover normal booting.
I booted machine from live USB and can decrypt data.

Can anyone please guide me or point me in the right direction (or literature)?

Thanks in advance.

Re: Sudden grub shell with LUKS encrypted partitions

Before this happened, how did the decryption cycle work: what did you originally configure to decrypt your partitions on boot? There are several ways to accomplish that, we don't know which route you took.

Edit: I recommend you use the "Report" button under your original post and ask a mod to move your post to "Newbie Corner"

It's LUKS on a partition.
Boot partition is not encrypted.

Decryption prompt were available just after initializing grub bootloader.

Re: Sudden grub shell with LUKS encrypted partitions

If /boot isn't encrypted, grub has nothing to do with LUKS, complete non-issue.

If you're dropped directly to a shell without a menu, that usually means the config is missing or damaged.

ok, done and done

From Live USB I
- decrypted drive
- mounted btrfs volumes
- chrooted
- recreated grub.cfg

Moving to newbie corner as requested

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
Try clean chroot manager by graysky

Yes. The way I described it.
It was newbie stuff indeed. I just didn't install Arch for some time and forgot basics
