I bought new MBP some days ago and it came with the lion installed on it. Now I am curious can I make an OS X Lion Bootable Disk?
I read some tutorial to make an OS X bootable Disk if you download it from appstore, but if Lion was installed by factory on it how can I make a bootable disk?
Best Answer
Open Terminal, and type this command to list all partitions on your hard drive or SSD:
Identify the "Recovery HD." For example:
Then run the following (replacing [ID] with your identifier (will most often be disk0s3).
So the following would look like:
The disk image inside the Recovery HD partition has been marked invisible, so use the Terminal command to mount it:
Now, from the newly mounted Mac OS X Base System Image, double-click the 'Install Mac OS X' application and proceed past the licensing agreement.
Choose the external drive or spare partition when the installer asks where you'd like to install OS X Lion.
Once the installer completes the download, do not restart your system. Rather, quit the installer. If you restart, you'll likely lose the local Lion installer. Once you have the InstallESD.dmg in the Mac OS X Install Data folder, you can burn it to a DVD, or image it to a USB flash drive to create your very own Lion boot disk.
