Translating the inxi

• The first disk nvme0n1 a mounted partition ext4 (ID-1) and unmounted swap partition (ID-1)

• The second disk nvme1n1 appears to contain a Windows installation (ID-2…5)

• The third disk sda contains a single ntfs partition (ID-6)

• The fourth disk sdb is a live ISO (ID-7,8)

Your efi partition is the Windows efi - which is located on /dev/nvme1n1p1

To be able to enter chroot which can work with your grub boot loader

You already checked the file system - no apparent errors

See → [root tip] [recovery] Basic Manjaro Linux Rescue and Recovery

First mount the root - then the $esp (do not mount on /run)

mount /dev/nvme0n1p2 /mnt
mount /dev/nvme1n1p1 /mnt/boot/efi

Then you can chroot into the mounted root

manjaro-chroot /mnt /bin/bash

Then you attempt to fix the system

pacman -Syu
