How to Install and Boot Mac OSX Leopard or Snow Leopard on an External Hard Drive

In this video, I will show you how you can install OSX Leopard or Snow Leopard on an external HDD, and then boot into it. In this video, I will be using a FireWire 800 HDD, but you can use a variety of devices such as a USB HDD, a standard Flash Drive, a SD card, or even an iPod.

For best results, use a FireWire 800 HDD.

@watchcartoonseries See my response above to Scootfast. Worked for me.

@Scootfast Yes, after you have the "Mac OS X Install DVD.cdr" showing on the left. Go to file, open disk image" and select "Mac OS X Install DVD cdr" This will actually mount it and you are good to go from there. Just simply clicking the sub source "Mac OS X Install DVD" (with no .cdr) should fill in the source field for you. Hope this helps!

This does not work in OS 10.7.2

- There is no erase destination check box in disk utility.

When you click "Restore" the following appears:

"To restore the disk image, Disk Utility must scan it first. To cancel the scan and stop restoring the disk image, click Cancel."

Then:

Unable to scan "INSTALL." (Resource busy)

Any clues anyone?

I have followed the steps many times and everything seems to be exactly as specified in the video.But, I always get the same result: a response that says "Restore Failure "could not find any scan information. The source needs to be image scanned before it can be restored". Any suggestions will be appreciated.
