I am following the instructions here: https://help.ubuntu.com/community/InstallingANewHardDrive

It says:

4) Create one partition occupying all the space on the drive:

(parted) mkpart primary 0 0

5) Check that the results are correct:

(parted) print

However when I do this I get:

$sudo parted /dev/sda
GNU Parted 3.2
Using /dev/sda
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted) mklabel gpt
(parted) unit GB
(parted) mkpart primary 0 0
(parted) print
Model: ATA Some SSD (scsi)
Disk /dev/sda: 240GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Disk Flags:

Number  Start   End     Size    File system  Name     Flags
 1      0.00GB  0.00GB  0.00GB               primary

The Start and End of 0GB and Size of 0GB is making me think this isn't correct. I would have thought the size should have been 240GB (or close to it). Are these instructions correct? If not, what is the correct way to make a single partition that covers the entire disk?

Using 0% for the start causes parted to automatically align the sectors for best performance:

(parted) mkpart primary 0% 100%

PS: u could also specify the filesystem type in same command, e.g for xfs:

(parted) mkpart primary xfs 0% 100%

Your mkpart line is wrong. The parameters are: partition-name, start-position and size.

In parted, run 

`rm primary` 
`mkpart primary 2048s 100%`

to remove the old, wrong, partition and recreate a new that spans the whole disk.
