You have a Recovery Partition:

Option: Reinstall Mac OS X does a clean install?

When you boot the recovery partition go into Disk Utility and wipe the Macintosh HD partition. Then quit disk utility and install Mac OS X Lion. It will be a clean install.

I am wondering whats the practical difference between erase and erase free space...?

 

[mdgm]

Erase free space will erase free space on the disk. This is a useful maintenance procedure with some SSDs.

The erase option will wipe the drive. With the drive wiped the Mac OS X installer will definitely do a clean install.

Thanks mate

I dont understand why erase procedure is a lot faster than erase free space.
