sda3/etc/fstab : # # /etc/fstab # Created by anaconda on Tue Nov 24 17:36:35 2020 # # Accessible filesystems, by reference, are maintained under '/dev/disk/'. # See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info. # # After editing this file, run 'systemctl daemon-reload' to update systemd # units generated from this file. # LABEL=local3slash / ext3 defaults 1 1 UUID=9d52b44c-eb94-4398-9f36-a415d0290e6b /home ext3 defaults 1 2 UUID=0899193d-734b-4b85-9d8d-7c334571e3bb /var ext4 defaults 1 2
Proposed strategy: boot live DVD su mount /dev/sda3 /mnt mount /proc /mnt/proc mount /dev /mnt/dev mount /dev/pts /mnt/dev/pts chroot /mnt
mount # from fstab should do /var and /home
grub2-install /dev/sda3 grub2-mkconfig > /boot/grub2/grub.cfg exit # out of chroot?
reboot
Should work?
