PC con linux mint 21.2 Victoria

cambie de disco la particion HOME no actualice /etc/fstab

Con live usb lo veo y edicto pero me sale esto y no la informacion
overlay / overlay rw 0 0
tmpfs /tmp tmpfs nosuid,nodev 0 0

Como logro edirtarlo con privilegios de escritura y edicion ya sea con live usb o con grubrescue

No estableci punto de montaje de la particion

If you want to edit the /etc/fstab file on an installed system, you need to first create a mount point (when booting a live usb), then mount the specific partition and to modify system files you need to be root (or use sudo). I'm not sure what you are trying to do but, if you change the /home partition to another partition and do not make the change in the /etc/fstab file, you will not have access on boot/login. If you boot to level 3, you should be able to manually mount /home as root (sudo on Mint). Not sure what the purpose is?
