Fresh installation of Lion on Mac without CD or USB stick

Lion has to be upgraded on Mac, however, you may want to have a fresh install of Lion to get rid of the old application or settings from the Snow Leopard. The following steps can be used to make a refresh Lion installation.
1. Upgrade Snow Leopard to Lion as Apple suggested from app store (paying for $29)
2. Reboot Mac while holding option key
3. Select the restore disk for starting
4. Select Disk Utility and erase the main hard disk drive. This may erase the old Snow Leopard.
5. Restore Lion, it will start a refresh Lion installation.

Cheers
Jonathan
