How to Install OS X Lion from USB Drive

Installing OS X Lion can be a bit of a challenge, especially if you don't have a physical copy of the operating system. However, there are several options available that allow you to install Lion without having to purchase a physical copy or download it directly onto your Mac. In this article, we'll explore some of these options and discuss their advantages and disadvantages.

One option is to use the Internet Recovery feature, which allows you to boot from a USB drive and reinstall Lion using an internet connection. This option is convenient because it doesn't require any advance preparation, but it does require an internet connection and can be slow. Another disadvantage is that you'll need to create the recovery drive before removing your old hard drive.

Another option is to create a Lion Recovery drive using Apple's Lion Recovery Disk Assistant. This option requires downloading the installer first (around 4GB) and has a larger storage requirement of 8GB or larger flash drive. However, once created, you can boot from this drive and reinstall Lion and recover from Time Machine without needing an internet connection.

You can also create your own Lion installer drive using a downloaded Lion installer app. This option is similar to the purchased installer, but it requires more steps and can be more time-consuming. Additionally, if you want to use this drive to install Lion on multiple Macs, you'll need to make sure that the drive is compatible with each of those machines.

Finally, you can purchase a Lion installer USB drive directly from Apple. This option is convenient because it comes preconfigured with the installation software and doesn't require any additional setup. However, it's also the most expensive option and may not be suitable for those on a budget.

In conclusion, there are several options available for installing OS X Lion without having to purchase a physical copy or download it directly onto your Mac. Each option has its own advantages and disadvantages, so it's important to choose the one that best fits your needs. Whether you're looking for a convenient and easy-to-use solution or a more cost-effective option, there's an installation method available for you.

Type or paste one of the commands below into Terminal, then press Return to enter the command.

* `sudo /Applications/Utilities/Lion\ Recovery Disk Assistant.app`

* `defaults write com.apple.LionRecoveryDiskAssistant.plist CreateRecoveryDiskAssistant -bool true`
