Using an existing disk with allocated partitions
| - h help |
| - z to delete all partitions |
| - A to autoallocate |
| - p g to print the partitions showing size in GB |
| - Autoallocation can leave unused space at the end of the disk which can
be manually allocated. |
- using usb
- select disk
- sd1 should be selected, else set it
Example files can be found at /etc/examples, they can be used for
reference.
| NOTE: Make sure only necessary lines are uncommented when copying to
