Ubuntu fstab; mount external drive at boot

Procedure for rescuing an Ubuntu Server when the boot file gets messed up due to a misnamed external hard drive.

Backup the current fstab file:

sudo cp /etc/fstab /etc/fstab.old

List the drives:

sudo blkid

Example output:

/dev/sda1: UUID="8F1B-7691" TYPE="vfat" PARTUUID="eea0152e-f8aa-4d1f-8d44-172261edd5a2"
/dev/sda2: UUID="5be250be-a857-11e8-9dd6-a82066361186" TYPE="ext4" PARTUUID="9ba42200-226c-4e67-a667-649658dfbd0b"
/dev/loop0: TYPE="squashfs"
/dev/loop1: TYPE="squashfs"
/dev/loop2: TYPE="squashfs"
/dev/loop3: TYPE="squashfs"
/dev/sdb1: LABEL="media" UUID="746622C40BE949C9" TYPE="ntfs" PTTYPE="dos" PARTUUID="e2bd323d-a7bb-4be8-83bb-4d547fb45e37"

Edit the fstab file:

sudo pico /etc/fstab

Example:

GNU nano 2.9.3 /etc/fstab 
UUID=5be250be-a857-11e8-9dd6-a82066361186 / ext4 defaults 0 0
UUID=8F1B-7691 /boot/efi vfat defaults 0 0
/swap.img none swap sw 0 0

#Device #Mountpoint #fs-type #options #dump #fsck
/dev/sdb1 /media/usb ntfs defaults 0 0

Save, reboot.
