Ok! Why would I mind? I would be more than glad to help you out with it. So, going ahead with it, basically what you were asking for can be done in 2 ways viz; Disk Utility or by using the ‘hdiutil’ and ‘asr’ commands. Initially, we’ll discuss the easier method of using the Disk Utility option of creating the boot up disk. The most ideal way to do it would be to do this from a drive which is not booted at present. It is definitely possible to image an active drive but please make sure that no applications are running and all are closed and there is hardly any use of the hard disk when the process of back up creation is on! This is how we do this:
- You need to start the Disk Utility application which can be located using the path Applications followed by Utilities
- Spot the file menu in the utility window and select the submenu which reads New
- When you click or roll over New, you will get pop ups which has Disk Image from Folder as an option
- You need to spot the drive that is supposed to be imaged and then click on the image button
- You need to provide the disk image that you intend to create, a name which will be permanent
- Go to the sub menu labeled with text: Image Format and from there select the option ‘Compressed’
- Your disk image will then be created, this created image will rightly appear on the left pane in the Disk Utility application
- Go to that image and click once on the image that is available on the left pane
- This action will be selecting the image, then move to the Images menu and select the option ‘Scan Image for Restore’
- In order to restore a disc image that you have created back to the hard drive. Follow the below mentioned steps
o Spot the tab which reads ‘Restore’ and select it.
o You will see the image in the left pane again, simply drag it from there to the Source Box
o On the very same left pane you will also notice the partition where you want to restore it, drag it from there to the destination box
o You should be checking the check boxes next to Erase Destination and Skip Checksum
o In order to complete the process and as a final command to execute the desired action, click on the restore button
