However, if you are going to create a Bootable DVD so that you can install it on other computers that are tied with different Apple IDs, you might want to reconsider doing this. Assuming that you have the same Apple ID on all of your computers and you simply want to create an installer for those computers, this is a good solution. The Lion Installer is tied to your Apple ID (unconfirmed) – many App Store purchases “sign” their apps to your Apple ID when you purchase/download via the App Store. It wont work with virtual machine cuz recovery mode can not connect with virtual machine.Note: if you are looking for instructions for Mac OS X 10.8 – Mountain Lion – please see this post.There are some important things to remember, though, before you embark on this effort.When you do that, you will see all of your Mac partitions.

For all Macs produced AFTER the launch of Lion, you can re-install Lion via the Internet. You can re-install Lion via an Internet Connection – this is a really cool option. ![]() If I Buy Lion Will It Be Available For Internet Recovery Download The LionRight-click on the Installer and select “Show Package Contents” Move the Installer out of the Applications folder (e.g., to your Desktop) Download the Lion installer from the App Store (see the steps above if you have already installed Lion) Here is what the contents of my Lion Installer DVD looked like:Apple – OS X Lion: About Lion Recovery – Mashable – HOW TO: Do a Clean Install of OS X Lion– (also shows how to do on a USB drive)So there you have it!
