Re-install clean formatted version of Lion.

Re-install clean formatted version of Lion.

Is there a quick way to do this?

I have looked online and seen various burn to DVD or USB Thumb drives which is fine, but I need to find the actual file?

I had 10.6.7 on my machine and downloaded Lion, and installed. I then believe that you can do a new "clean" install of Lion once its on there?

I re-booted with cmd+R but even with the fresh install setting it still keeps and retains everything after a lengthy re-install process?

I have backed up and want to do a CLEAN brand new install of the latest Lion reformat? - Is this possible?

Can I do it from the installed Lion file, or do i need (and is it easier to burn to DVD) the Lion file - if so whats it called and where would it be?

Would I need to download it again to burn it? but the App Store says its "purchased" - i thought if i re-downloaded as i've already paid I could do that?

Any help would be great

MacBook Pro i7 8GB - iPhone 4, Mac OS X (10.6.7)

Hi,

Back in the ends (when just released), I used the following guide (as I did a full clean install):

Apple also released the Lion Recovery Disk Assistant that may be useful for you:

I hope that helps :-))

You cannot install when on 10.6.7, you 10.6.8 to install Lion.

After the donload of Lion you can make a thumbstick or CD of the Lion installer by finding it in the downloaded package like Josee said.

If you have already installed Lion, without making a copy of the installer first, you have to download it again !!!

Do it like in this expose:

Once you’ve purchased Lion, find the Lion installer on your Mac. It’s called Install Mac OS X Lion.app and it should have been downloaded to /Applications.
Right-click (or Control+click) the installer, and choose Show Package Contents from the resulting contextual menu.
In the folder that appears, open Contents, then open Shared Support; you’ll see a disk-image file calledInstallESD.dmg.
Launch Disk Utility (in /Applications/Utilities).
Drag the InstallESD.dmg disk image into Disk Utility’s left-hand sidebar.

Not quick, but after you boot into Recovery, select Disk Utility, then Erase your Macintosh HD Volume, quit Disk Utiltiy, then selet Reinstall OS X Lion
