Mac OS X Installation from Hard Drive

If the optical drive is busted or you want to quickly install OS X, put the OS X Installation disc on a external hard drive and boot from that drive.

Steps

1. Create a dmg-image of the Installation disc using Carbon Copy Cloner
2. Open Disk Utility and pick the external drive from the menu on the left to put the image on
3. Go to the Restore tab and click Select and find the dmg-image
4. Second, drag the external hard drive icon from the list on the left to the Destination field
5. Check Erase drive and click Restore, after a few moments the image will be successfully dumped to the drive
6. Once done, shutdown and replace the old system drive with a new one if necessary and press power to start-up
7. Hold the Option key (between CMD and CTRL) to enable the boot screen where the available boot drives will show up
8. Select the Installation disc and follow the standard installation process
