Using

Call createGPT with no arguments for general help on usage and flags.

Add a partition using the following flag. Specify it multiple times to add multiple partitions.

--part <path> [--type <GUID|preset>]

<path> is a filepath to the contents of the partition.

--type can be passed either a GUID, or a type preset.

Presets:

• null -- 00000000-0000-0000-0000-000000000000
• system -- c12a7328-f81f-11d2-ba4b-00a0c93e3b00

When passing GUIDs over the command line, use the following format:

00000000-0000-0000-0000-000000000000

Put the values in mixed-endian, canonical fashion.
