Welcome to fdisk (util-linux 2.27.1). Changes will remain in memory only, until you decide to write them. Be careful before using the write command.

Device does not contain a recognized partition table. Created a new DOS disklabel with disk identifier 0x30d8c8fe.

Command (m for help):

m

Help:

DOS (MBR)

a toggle a bootable flag

b edit nested BSD disklabel

c toggle the dos compatibility flag

Generic

d delete a partition

F list free unpartitioned space

l list known partition types

n add a new partition

p print the partition table

t change a partition type

v verify the partition table

i print information about a partition

Misc

m print this menu

u change display/entry units

x extra functionality (experts only)

Script

I load disk layout from sfdisk script file

O dump disk layout to sfdisk script file

Save & Exit

w write table to disk and exit

q quit without saving changes

Create a new label

g create a new empty GPT partition table

G create a new empty SGI (IRIX) partition table

o create a new empty DOS partition table

s create a new empty Sun partition table

Command (m for help):

n

Partition type p primary (0 primary, 0 extended, 4 free) e extended (container for logical partitions) Select (default p):

p
