Using the recovery feature (Command-R) will connect you to Apple's Servers. It will give you the options to either restore from a Time Machine backup, reinstall Lion (from Apple), or repair/erase your hard drive using Disk Utility.
Choosing reinstall will leave all your files and folders and reinstall the OS. As far as I know, there is no "clean install" option unless you want to use Disk Utility to erase your hard drive which will erase everything - at least while I've tested the feature.
So could you essentially use the Disk Utility to erase the hard drive then use the reinstall lion option to do the same thing as MAC_HD wanted to do?
I'm trying to do the same thing; I just want to delete everything, but still end up with lion.
I have early 2011 mbp 13", originally snow leapord but upgraded to lion. Thanks!
Pretty much, will you still be able to use the reinstal lion feature after you delete your hard drive
If you boot to the Recovery HD and Erase the Macintosh HD parttition, erasing your current install of Lion, thenn yes you use Rinstall Mac OS X from that same screen to download and install Lion again.
But you will need your Apple ID and password for your ID to do it as yours is an upgrade from Snow Leopard.
No need to Reinstall Snow Leopard.
