How to delete recovery partition Windows 7

In order to Install linux (Ubuntu 12.04.3 LTS) I needed to make some space. Windows 7 was installed with 4 primary partitions. Windows usually needs 2. One for is system reserved and the other one is the C: drive. But my installation had 2 more for a System Recovery (12.8GB) and a HP Tools(104MB). The reason you need to remove them is becasue Linux also needs to partitions: The main OS and the swap space, and you cannot have more than 4 primary. So, this video helped a lot on how to re-partition with windows partition manager. Cheers.
