I thought you said it was already installed at the repair shop. Why, then, do you need to reinstall it?
Are you doing this:
Install or Reinstall Lion/Mountain Lion from Scratch
Be sure you backup your files to an external drive or second internal drive because the following procedure will remove everything from the hard 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:
1. Select Disk Utility from the main menu and click on the Continue button.
2. 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.
3. Set the format type to Mac OS Extended (Journaled.) Optionally, click on
the Security button and set the Zero Data option to one-pass. Click on
the Erase button and wait until the process has completed.
4. Quit DU and return to the main menu.
Reinstall Lion: Select Reinstall Lion/Mountain Lion and click on the Install button.
Note: You will need an active Internet connection. I suggest using Ethernet if possible
because it is three times faster than wireless.

Thanks for your reply. I tried this many times before posting to the forum. The restore partition appears to only be on the disk. I read that this is automatically configured when installing lion. The new hard seems to verify ok with no errors. The built in optical drive isn't working. Can the system be installed via apple support any other way? Remotely.
I only have a snow leopard cd and have even tried to install this via target disk mode in desperation. Not a hundred percent certain what is the correct operating system for this mac to run smoothly. I'm assuming lion is the operating system shipped with mac because of the partition. Sorry I'm being vague but it's been hanging around in my husbands office until it went to the repair shop. Should I try to get a retail version of lion and install that via target disk mode. Can I buy a better version of the operating system and install because I read that lion isn't great anyway.

I've only tried this wirelessly. Maybe the function will work if I use Ethernet instead. Will try this and get back to you to see if this solves the error.

I'm puzzled still. Was OS X installed for you on the new drive by the repair shop? Are you saying this drive is blank but it has a Recovery HD partition? I'm puzzled how that could happen because one must install Lion or Mountain Lion to a new drive in order to get the Recovery HD partition. There is nothing wrong with Lion.
Here's what I'd like you to do. Open Disk Utility. Select your disk entry, the entry that displays the disk manufacturer, drive model number and size. Click on the Partition tab in DU's main window. Now, press COMMAND-SHIFT-4. Use the crosshairs to select the entire DU window. When you release the mouse button an image file will appear on your Desktop. Use the Camera icon you see in the toolbar of the message composition window here and post your image in the message.
