Install PureOS with manual partitioning
=======================================

This procedure will install PureOS with manual partitioning.
The partition layout shown below works for any size disk, including disks larger than 2 TB.

If you are familiar with partitioning a Linux system, you can also customize the partition layout, such as to use a second SSD.

Boot your system from the :ref:`PureOS live installation medium <pureos_installation_media>`.  When the desktop appears, follow the steps below to install PureOS.

#. Start the Calamares installer.  Click **Activities** in the upper-left corner, then click **Install PureOS**.
