I’ve been having issues with GRUB since installing and uninstalling Windows. I replaced it with another Manjaro install and the issue fixed itself. However, I removed the new install and resized the main one, thinking I could fix GRUB later.
I also tried reinstalling in a separate partition to access GRUB, and booting into the main one returns
mount new_root: wrong fs type, bad option, bad superblock, missing codepage or helper program, or other error.
When I try to access the partition from a live USB, I get this:
[manjaro manjaro]# manjaro-chroot -a grub-probe: error: cannot find a GRUB drive for /dev/sdb1. Check your device.map. grub-probe: error: cannot find a GRUB drive for /dev/sdb1. Check your device.map. ==> Mounting (ManjaroLinux) [/dev/sda1] --> mount: [/mnt] mount: /mnt: wrong fs type, bad option, bad superblock on /dev/sda1, missing codepage or helper program, or other error. Can't open /mnt/etc/fstab: No such file or directory. mount: /mnt/proc: mount point does not exist. mount: /mnt/etc/resolv.conf: mount point does not exist. chroot: failed to run command '/bin/bash': No such file or directory --> umount:  umount: bad usage Try 'umount --help' for more information.
Also, when using
fsck I get:
[manjaro@manjaro ~]$ sudo fsck /dev/sda1 fsck from util-linux 2.36.1 e2fsck 1.45.6 (20-Mar-2020) The filesystem size (according to the superblock) is 120680448 blocks The physical size of the device is 94370560 blocks Either the superblock or the partition table is likely to be corrupt! Abort<y>?
Any advice would be appreciated!
EDIT: I would also be fine with a recommendation on how to safely recover the files and copy them to an external drive
