Formatting MBP with pre-installed Lion
I just bought a 2 months old MBP running OS X Lion. (late 2011)

The MBP was not formatted by the previous owner, so I wanted to format and make a clean install, but there is not DVD to boot.

So restarted pressing command + r to open the disk utility. I can format the MBP there, but after that, how can I install OS X Lion if there is no DVD to boot?

When I format there is a partition named "disk 1 - Mac OS X Base System". Is this the pre-installed Lion? This will not be erased after formatting it?

Thanks,
