It looks like we have conflicting information here.
- GRUB core image is not found at sector 2048 (sda1).
- but sda1 file system is identified as "BIOS Boot partition".
- parted and blkid find a ext4 filesystem in sda1.
- but sda1 is not mounted
Maybe the ext4 filesystem which was mounted on /boot and the GRUB core
image corrupted each other.
Can you mount /dev/sda1 ?
Can you show the contents of /boot and /etc/fstab in mounted
/dev/mapper/sojourn-root ? Unfortunately boot-repair did not.
