Reinstalling Lion

Fortunately, thanks to a new utility called UniBeast from tonymacx86, of course , that's no longer a problem. UniBeast not only allows you to create a bootable Lion flash drive for a hackintosh, but it also removes the need to use an iBoot CD to boot. This mean you no longer need an optical drive to create a hackintosh.

You format that drive with a single partition with a Master Boot Record partition scheme. Once formatted, you run UniBeast and it will take care of all the magic for you. When it's done, you'll be able to boot from it and install Lion. So how do you do it right?

Most importantly, make redundant backups. If you only have one backup, remember that when you erase your hard drive, those backups become the one-and-only copy of your data.

Before erasing the hard drive, make sure you have a minimum of two completely separate backups, on completely separate media, and preferably made with two different backup programs. I highly recommend Time Machine to back up to one hard drive or a Time Capsule, and Carbon Copy Cloner to back up to one or more additional hard drives. The system should eventually boot into the installer, where you first must choose a language.

Do so, then choose Disk Utility from the Utilities menu.

When you see the Apple logo, you can let go. This will start the computer in recovery mode. Once you have fully booted into recovery mode, open Disk Utility. Note that when you begin the install process, you will need to download about 4 GB of data, so be sure your internet connection can handle that before proceeding.

Once in Disk Utility, you need to select your hard drive in the list and select the Erase tab.

This step is pretty simple — just follow the directions to reinstall the system on the newly-erased drive. Instead, when the installer finishes, import nothing, and go through the setup process as if this were your first computer. Once your system restarts successfully, you will need to be sure that it is fully up-to-date. From the Apple menu, choose Software Update, and install any updates that show up. If you reinstalled Mac OS X Once your clean, new system is up and running and fully updated, work on getting all the settings back to the way you like them.

At this point, you can manually copy your user data from the clone backup back into your new user folder. When it comes to restoring data for apps that are not document-centric, like iTunes, iPhoto or Mail, you need to find and copy the data from your backup to the same location on your new drive. For other apps, you may need to search for instructions on where to find the data and preference files. At this point, you can start reinstalling any other applications you might have had installed.
