In Mac there are various methods available for creating bootable Dvd. One can create it using Apple's disk utility or using third party recommended application.

Although there are many important reasons to create Mac bootable dvd but here some important one's are mentioned:

Disaster can happen anytime so it is advisable and good to have a bootable disk always in order to be prepared for it.

It is essential to create an emergency disk for the security of data from drive crash.

Apart from the above reasons it is also needed when someone want to install Mountain lion on multiple Macs. It means creating bootable install drive would be more easy and efficient process than downloading and copying the entire drive to each machine.

Among various methods of creating Mac boot dvd first we will discuss with the Disk utility application.

Requirements before making a bootable install drive: 

·        You need a copy of the install OS X Mountain Lion app (make sure you have the latest version of ML installer).

Even if you previously had this, recheck it in your application folder as it may not be on your drive, because OS X unhelpfully deletes it once after it get used by you. If you didn't find it, redownload it from App store.

·         Next, you need to extract the InstallESD.dmg file(the file that is used to create the install drive) from the app’s store package.

Process to extract InstallESD.dmg file:-

·        Now, right-click or control-click on the Install OS X Mountain Lion app and from the contextual menu choose Show Package Contents. Then a folder will appear to you.

·         Open Contents and then open 'Shared Support'. Inside it you'll see your desired file InstallESD.dmg.

Creating bootable drive or emegencey disk using Disk utility app:

·        Launch Disk Utility (inside /Applications/Utilities)

·        Now, drag the InstallESD.dmg file onto the left side of the Disk Utility window.

·        Using Disk Utility, in order to mount disk image in finder, select the file and then click 'Open' .

·         Now, inorder to restore this image, select Mac OS X Install ESD in the left sidebar of Disk Utility and click Restore tab.

·        Now, drag the Mac OS X Install ESD icon into the Source field.

Now, you are ready with your flash drive. This process will erase the drive, so make sure to take backup or clone of the data that you want to keep safe.

Connect the flash drive and then find it in your Mac Disk Utility.

Drag this flash drive into the Destination field of Disk utility.

Click Restore and then Erase it with the resulting dialog box.

Now, you need to enter an administrator username and password. It will take some time to format the drive. 

But, unfortunately this method won't work in every case. For example if you buy a 13-inch Mac Book Pro with Retina display or newest iMac, such models use OS X 10.8.2 version which is not available from Mac App Store. So, you should either use the Recovery Disk Assistant method, third part application or wait for updating OS X 10.8.3.

Also note that, in case you have a new iMac with Fusion Drive, Apple states that the Disk Utility version that comes with Fusion Drive is unique. But, earlier versions of Disk Utility can’t be used with a Fusion Drive.”

So, it is great to take clone of your Mac drive in some external drive. 

Creating bootable dvd using some third party application like Stellar Drive Clone is great and easy task. It enables you to create image, restore backups and clone individual volumes including recovery disk.

It supports window file formats in your Mac drive and gives you fascility for creating emergency drive within few clicks. One can create bootable clone of their Mac OS X 10.3 or later versions.
