Installing a new operating system over the old one can create problems with stability. Apple disregarded these concerns with the release of Mac OS X 10.7 Lion by only allowing the initial release in the Mac App Store for download. A USB Flash drive version will become available in the future, but there is a way to get a clean install from a DVD or USB Flash Drive now with some effort.

We will show you how to create your own installation DVD or USB Flash Drive. For now those are your only two options since Macs won’t boot from an SD card. In the case of the Flash Drive we will also show you how to put two partitions on one 8GB or larger flash drive so that you will also have all your Mac apps on the drive ready to install after you install the OS.

Why Make an Install Disk

Why would someone want to create an install disk instead of install Lion on top of their old OS X installation the way Apple wants? While it seems to work well in our experience, here are a few reasons to go through the trouble:

Clean install of an OS is usually more stable
Forces user to clear out old file and app clutter that is not used anymore saving drive space
A future hard drive crash might leave you unable to install from the Mac App Store or the new Lion Recovery feature
Your are a geek and trying technical stuff on a computer is fun

While the first two and last option are good reasons, the third is the most important. This is a backup plan so you don’t have to take your computer to Apple to fix it if the hard drive or SSD drive won’t boot anymore. A clean install usually fixes these kinds of problems.

What You Need

In order to do this you will need the OS X Lion installation file. If you already upgraded to Lion the install image is deleted by default and it is already too late. Some other sites have posted that you can re-download the file. But the only way to do that is on a system that doesn’t already have Lion installed. The only way to do this is to use your computer’s restore disk to reinstall Snow Leopard or an earlier version of OS X. Do this before you install Lion but after you download it from the Mac App Store.
