I have been saved many times using an image from a competing product, however it was always a FULL DISK image.
If I make a "System" backup, and my computer will not boot, can I just restore the OS by using the System backup, WITHOUT having to restore my apps, settings and data? In other words, will it just repair the OS by replacing the OS with an image of it that previously worked? Seems like that would be much faster than restoring the entire disk.
