After reading ALL the topics on how to make Lion bootable from a USB drive for a clean install, all the topics i have read on the net seem to be wrong.. There is noInstallESD.dmg or OSX Lion.app or anything...

There is not even a icon or app in the app folder?

So i have it installed via mac app store on my MBP but i want to make a bootable Lion on a flash drive? not possible?

I have tried searching thru spotlight and the following way...and nothing!!!

First we are going to locate the Lion InstallESD.dmg file and mount it:

Navigate to your applications folder
Right-click (or control-click) on the “Install Mac OS X Lion.app” and select “Show Package Contents”
Open the “Contents” directory and then go into “SharedSupport”
 
Hold alt while clicking "install" in the AppStore. This will prevent the AppStore from checking your version.

Sweet, thanks! :) Also, there was a message about a newer version of this app already being installed and needing to delete the older version...somehow I got around this either by clicking on Install multiple times or holding down alt while clicking on Install. Downloading for the second time. Thankfully I have a fat pipe.
 
Does it automatically install, or do you have to click-to-install after it downloads?

I'm going to tell you in a minute. I think after the 3.74 GB file downloads you have the opportunity to quit the installer, in other words you have to click to install.


UPDATE: Yep, you just quit the installer and now you will find that the "Install OSX Lion" file is in the Applications folder.

Awesome!
Did you find the InstallESD.dmg file? Or are you not going to burn a copy of Lion?
 
I'm also wondering about this. I just bought a brand-new Macbook Pro last week so I don't have much to lose. I'd like to install Lion completely fresh, but it appears that's not possible in an official, supported way via the App Store. So the alternative is to grab this file and do it the old-fashioned way by burning it on a DVD or restoring to a flash drive? Too bad the installer doesn't give an option to wipe the drive completely and then install Lion...
