    Personally I downloaded the installer, then ran Lion Disc maker to make a ML USB flash stick, boot to it and then run Disc Utility from the installer and erase the drive and repartition. From there get out of Disc Utility and run the install. When it comes up after finishing the install you have a factory fresh ML install.

    You can also hold down option when booting. go to recovery mode. Then select the disk utility.. wipe the drive using one of the secure options. Then install lion in there. You will need a valid apple id that you used to purchase Lion, it will download it and install it for you.

    It does take a little while but it's less effort hehe.

    Agreed. My way when you're done you walk away with a USB installer though :)

    How long it takes is pretty subjective. Since you're downloading the installer either way it's subject to bandwidth and how busy Apple's servers are. Once you get the image down it's in the 45mins ballpark.

    Either Dissnt's way or my way is correct at the end of the day though.

    Recovery

    If I am correct, you can hold down R on the keyboard while turning on the mac, and it will download the recovery program. Erase the HD with disk utility, and reboot. :)

    If you have a recovery partition, this is easier.

    Want to volunteer what YEAR your MBP is? may make a difference to the exactitude of the procedures.

    Of course it works. By default OSX restore will just reinstall the operating system but it'll leave your user data intact.

    If you want to wipe everything and start fresh, boot to the recovery partition command+R, and use Disk Utility format your drive. Then you can use the installer to put a fresh copy of the OS on there.

    If you buy it in the App store then yah when you boot in recovery you can download and install it there after you wipe the drive.
