Like other versions of OS X, Snow Leopard can be installed from a USB drive. This is especially beneficial to Macbook Air users looking to install the OS without a DVD drive. To do this, you’ll need to prepare your USB drive with the installation files. Like many of our other Mac Help articles, the steps listed below worked particularly for Snow Leopard but should also work for installing OS X from USB on Leopard.

After you’ve gotten the correct USB device, connect it to your Mac and prepare it with the Snow Leopard installation files by following these steps:

This includes updating the options for the partition so that it is set to a GUID partition. If the USB drive is not bootable you will NOT be able to install from it.

Open Disk Utility and select the Flash Drive
Select the Erase tab on the right and then set Format to Mac OS Extended (Journaled). Name the partition you’ll be creating Snow Leopard or OS X Install so you can keep track of your installation device. After you’ve done this, click the Erase button.
After Disk Utility finishes erasing your old data on the flash drive and setting it as a new partition, it will be ready for the Snow Leopard install files. Select the Restore tab at the top and then drag the Snow Leopard DVD to the Source field. Select your USB device for the Destination file. Click Restore and wait for the restoration to finish (about 20 minutes).
If the restoration worked correctly you should be able to open your USB device and see the Leopard installation files. If you try and click the Install OS X Snow Leopard icon, you’ll get the message below telling you you can’ install OS X from this volume. IGNORE the message. The next steps will walk you through the installation steps.
Now that the installation files are successfully on your USB device, be sure to remove the Snow Leopard installation DVD from your drive. Next, restart your Mac and when it first starts to reboot, be sure to hold down the option (alt) key on your keyboard. After a few seconds at least two volumes should appear for you to select from for installation. One of those will be the USB drive we just prepared. Select it.
After the Snow Leopard installation software boots from your USB drive, follow the on screen instructions for installation.
