Any OSx86 installation guide can seem daunting at first glance, especially when trying to remember cryptic terminal commands and sorting through volumes of misinformation on the web. This guide requires no coding, terminal work, or Mac experience of any kind.
Because Apple is only distributing OS X Lion through the Mac App Store until next month, we’ve had to rethink our retail installation method. What follows is our recommendation for the easiest, cleanest and most Mac-like installation process. For best results, follow this guide to the letter.


You will need: 
A System Running Mac OS X Snow Leopard 10.6.6 or later with:
  • Intel Core 2 or above, 64 bit CPU
  • Mac App Store Account + $29.99
  • Internet Access to Download 4GB OS X Lion App through Mac App Store
  • 4GB space available in /Applications
  • 8GB additional free space on your hard drive
  • Mac Pro 3,1 system definition and the latest Chimera Bootloader from MultiBeast
Don’t have Snow Leopard yet? To install Mac OS X Snow Leopard from the Retail DVDfollow iBoot + MultiBeast.
STEP 1: Purchase OS X Lion from the Mac App Store

1. Boot into your existing Snow Leopard installation.
2. Download the OS X Lion App directly from the Mac App Store - it will automatically open.

 3. Click Continue.
4. Target your currently booted Snow Leopard drive and hit Install. This will not install the OS or affect this drive in any way. It will simply install the files necessary to do so later in the process. 

  5. Click Restart to reboot.
STEP 2: Prepare the Installer Partition

1. Boot back into your existing Snow Leopard installation.
2. Open /Applications/Utilities/Disk Utility

     3. Highlight your Snow Leopard drive in left column.
     4. Choose the Partition tab, and Click the + to Add a Partition.
   5. Name the secondary partition Installer with a size of 8 GB and click Apply.
 6. Click Partition.
