How to re-format mid-2010 MBP with 10.8.5

[Macinthelou]

I have a mid-2010 MBP (2.66 Ghz Intel Core i7 with 8GB 1067 MHz DDR3 RAM and Intel HD Graphics 288 MB) running 10.8.5. I would like to completely re-format the computer (i.e wipe the HD other than the OS).

Could someone give me instructions on how to do this?

Or alternatively, should I consider upgrading to a more recent OS?

Thanks!!!

Create a USB drive with the mountain lion operating system and restore from that as a clean install.

At boot hold down command N. That will put you into net boot and let you reinstall the OS.
