My MAC was working fine and at that point from Disk Utility, selecting the main disk, I clicked on "New Image" and saved the entire disk as a backup. It resulted in a 135Gb dmg file. Then I save it to a USB hard disk where I have some other files (pictures, movies, etc).

After some time I screwed up the system with some "cleaning" application and had problems at boot up.

I considered that I have no problem since I have the dmg backup. So I booted up from the original SL disk and selected from Utilities menu, "Restore System from backup" but it does not see the USB hard disk where the image is saved. (?!)

Then I went back to menu Utilities/Disk Utility and noticed that my USB drive it does shows up. I clicked on the main disk (with the damaged boot), selected the "Restore" tab, then selected the dmg image from the disk, selected where to restore and and Go... but I get "+Restore Failure, Could not find any scan information. The source image needs to be imagescanned before it can be restored+" ...and now I am stuck! What this message means and how I can get around it to have a successful restore?
Do I have to erase the partition of the original disk before?
Thank you.
