Using a recovery image for restore a laptop is not a simple process, but it’s something we all have to go through at some point. There is really no one way to do this – every platform and computer has its own process. In Chrome OS you have to use the image burner at chrome://imageburner. Google is trying to make this process much simpler and universal, though.
The Chromium team is currently working on a Chrome OS Recovery Tool app. It will take advantage of the imageWriterPrivate API to make it easier to write images. These can then be easily put in removable storage and used at one’s will.
I hate having to go through this process, so any tool that makes it easier to restore a computer is welcome! Let’s wait and see when this app is released.
