Partitions creation

Example how to create partitions on SATA disc

root@imx8mq-voipac:~# umount /dev/sda
umount: /dev/sda: not mounted.
root@imx8mq-voipac:~# fdisk /dev/sda

The number of cylinders for this disk is set to 44457.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
   (e.g., DOS FDISK, OS/2 FDISK)

n       add a new partition
o       create a new empty DOS partition table

q       quit without saving changes
s       create a new empty Sun disklabel
t       change a partition system id
