4 To install optional software, click Customize.
5 Click Install.
You can install Mac OS X and Lion Server without erasing the disk, which saves your
existing files and settings, or you can erase the disk first, which erases all your data
and leaves the computer ready for you to reinstall Mac OS X, Lion Server, and Apple
applications.
After reinstalling Mac OS X, you can then go to the Mac App Store and re-download
the applications that came with your Mac and other apps that you purchased from the
Mac App Store.
Important: Apple recommends that you back up the data on the disk before restoring
software. Apple is not responsible for any lost data.
Restoring Your Computer to Its Factory Settings
When you restore your computer to its factory settings, everything on your computer
(your user accounts, network settings, and all of your files and folders) is deleted. Before
you restore, back up any files you want to keep by copying them to another disk.
Write down your network settings from Network preferences to make it easier to get
connected again after reinstalling Mac OS X Lion Server.
1 Make sure your Mac Pro is connected to the Internet via an Ethernet or Wi-Fi network.
(To connect to a Wi-Fi network, follow the instructions on page 82).
2 In the Mac OS X Utilities pane, select Disk Utility and click Continue.
3 Select the disk in the list on the left, and then click the Erase tab.
4 Choose Mac OS Extended (Journaled) from the Format pop-up menu, type a name for
the disk, and then click Erase.
