The next partition will be mounted at /boot, so a disk space of 300 MB should be enough. Setting the file system type here is not important. That, will be taken care of when you return to the main installation window. OK.

The third partition, I intend to mount at /. I assigned 10 GB to it, but because /usr was on a separate partition, I came to the conclusion that this was too much. If you want to, you can assign about 5 GB to this partition.

The fourth partition will be used for Swap, disk space that the system will use as virtual memory. A disk space of 2000 MB or 2 GB will do. The rest of the space was assigned to the partition that will be mounted at /home and /usr.

That should bring you back to the main. And this is where the partitions will be assigned mount points, and formatted with the file system of your choice. For each partition, select it, then choose a mount point from the dropdown menu to its right. Click on Format.

Then select the file system, and click on OK. When all the partitions have mount points and formatted with a file system, click on Next to complete the installation.

This is a view of the partitions on a running installation of Chakra 2011.4. In another test installation, I actually configured separate primary partitions for /var, /tmp, and /opt. It was just for fun, just to show what GPT brings to the table.
