Extra remark concerning hard drive partitioning

Because EFI is used on a GPT partion tabel a few things should be considered.
GPT does not allow extended partioning.
If you are installing Linux with, for example, 3 partitions (e.g. /, /home, /swap) you need to create these on primary partitions. GPT partition table allows you to create more then 3 primary partitions.

Example

Two installations (Xubuntu 12.04 and Ubuntu 12.10 ... with encrypted /home partitions)

Partition Mount point Description
/dev/sda1 /boot/efi EFI
/dev/sda2 / Xubuntu 12.04 /
/dev/sda3 /home Xubuntu 12.04 /home
/dev/sda4 swap Xubuntu 12.04 swap (*)
/dev/sda5 / Ubuntu 12.10 /
/dev/sda6 /home Ubuntu 12.10 /home
/dev/sda7 swap Ubuntu 12.10 swap (*)

* the two swap partitions are necessary for the two encrypted /home partitions

** gparted will not recognize the swap partitions as such due to encryption
