If you wish to manual set up partitions, as an advanced option you will have to choose which file-system you want. A file-system controls how your files are accessed at lower levels on the disk. If you are booting your computer in UEFI mode a more modern firmware compared to BIOS you will need to create an EFI system partition see `efi system partitionwikipedia <https://en.wikipedia.org/wiki/EFI_System_partition>`_ for more detail to create this partition you will need a FAT32 file-system with the ESP flag with to be mounted at /boot/efi/ under the mount point. You will also need a root (/) file-system, several file-systems included for Lubuntu are Ext4, XFS, and Btrfs.
