May 13, 2012 1:28 PM in response to Dr. Bakhtiarby Kappy,Install or Reinstall Lion from Scratch
If possible backup your files to an external drive or second internal drive.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Erase the hard drive:
- Select Disk Utility from the main menu and click on the Continue button.
- After DU loads select your startup volume (usually Macintosh HD) from the left side list. Click on the Erase tab in the DU main window.
- Set the format type to Mac OS Extended (Journaled.) Click on the Erase button and wait until the process has completed.
- Quit DU and return to the main menu.
Reinstall Lion: Select Reinstall Lion and click on the Install button.
Note: You can also re-download the Lion installer by opening the App Store application. Hold down the OPTION key and click on the Purchases icon in the toolbar. You should now see an active Install button to the right of your Lion purchase entry. There are situations in which this will not work. For example, if you are already booted into the Lion you originally purchased with your Apple ID or if an instance of the Lion installer is located anywhere on your computer.

Jun 1, 2012 6:05 AM in response to Kappyby boilercardinal,Kappy,
I have a very similar situation to Dr. Bakhtaran with a twist. Since I don't need a snarky reply, I thought I'd ask for your assistance directly.
My employer sent me my MacBook Pro (15" 2.2 Ghz Core i7, Mac OS X ver 10.7.3) three weeks before they sent the instructions to not turn it on, etc. Since we normally have to turn on equipment to gather mac addresses etc., I did. Since I have an apple account, I did that too. During setup, I felt like I was a rabbit going down a hole and I was right.
Now, four weeks after the fact, we are trying to remote setup this machine and they are having all sorts of problems. We re-installed OS X last night and after it had re-installed, my ugly face was there wanting my personal login and password.
Can this be undone? There are no physical start-up disks.

Jun 1, 2012 1:26 PM in response to boilercardinalby Kappy,Lion installs both itself and a Recovery HD. Booting the latter is how you reinstall Lion or fix things with Disk Utility. So, what you can do is this:
Install or Reinstall Lion from Scratch
If possible backup your files to an external drive or second internal drive.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Erase the hard drive:
- Select Disk Utility from the main menu and click on the Continue button.
- After DU loads select your startup volume (usually Macintosh HD) from the left side list. Click on the Erase tab in the DU main window.
- Set the format type to Mac OS Extended (Journaled.) Click on the Erase button and wait until the process has completed.
- Quit DU and return to the main menu.
Reinstall Lion: Select Reinstall Lion and click on the Install button.
Note: You can also re-download the Lion installer by opening the App Store application. Hold down the OPTION key and click on the Purchases icon in the toolbar. You should now see an active Install button to the right of your Lion purchase entry. There are situations in which this will not work. For example, if you are already booted into the Lion you originally purchased with your Apple ID or if an instance of the Lion installer is located anywhere on your computer.
Now, this will completely erase the volume in which Lion is currently installed. When you then reinstall Lion it will be like coming fresh from the factory ready for a new user. I hope this is a working solution for your problem. If it is not, then I would encourage you to create a new topic more relevant to your needs which will solicit others to offer help. That isn't going to happen in someone else's already old topic. Had I not forgotten to stop email notifications from this topic, then I never would have been aware or your post.

Apr 29, 2013 9:28 AM in response to Kappyby dhaberman,Kappy,
Ok, I have a variation as well.
I inherented a MacBook Pro at work. On their last day, the person who had the Mac tried to reset the Mac to the factory settings. (I was off that day). He left it with the admin and left himself. After many hours of something (She can't tell me what) said it still had 4 hours to complete another person told her it was frozen and she shut it off. Wen I got the Mac today, as best as I can tell there started the Restore since it appears they already did the delete. When I leave DU and select Install Loin to the Macintosh HD it takes me to the App Store login. When I log in with my ID it gives me a message that I must sign in with the APp Store ID that purchased Lion, which of course was the pervious employee. So I am guessing that I am going to have to purchase Lion again myself, which is ok, but I can not see a way to do this. Can you help?
