Grub corrupt

grub

#1

On 01/24/2019 I accepted updates by Open Packet Manager. After shutdown and power up I got

error: symbol ‘grub_key_is_interrupt’ not found.
Entering rescue mode…
grub rescue

I tried Restore the GRUB Bootloader several times. Booting Manjaro from USB-Stick, running “Detect EFI bootloaders ” and selecting the Manjaro bootloader works fine.

What’s going wrong/How can I debug this?

Thanx for any hint,

Renne

cat /etc/lsb-release
DISTRIB_ID=ManjaroLinux
DISTRIB_RELEASE=18.0.2
DISTRIB_CODENAME=Illyria
DISTRIB_DESCRIPTION=“Manjaro Linux”


Grub_key_is_interrupt
#2

Boot up (your way - usb stick, detect efi bootloaders…) At terminal, provide output of all commands below,

pacman -Q grub
cat /etc/default/grub | grep GRUB_TIMEOUT
cat /boot/grub/grubenv | grep -v '#'
findmnt -s

Tell us,
o Is Manjaro your only OS there?
