Firstly, what is G4U, LVU?
And secondly, did your friend mention any REASONS why they prefer G4U? Have they usd Ghost? If so, which version?
Most people that prefer imaging prgms other than Ghost cite "user-friendliness" as a top reason. Folks who prefer Ghost typically cite "reliability" as top reason. So it depends on what you're looking for in an imaging program.
It's just like buying a car. Do you want great gas-milage? .. or to go off-roading? Or something that goes FAST? .. like a Porsche. Or to haul around a bunch of kids. It depends what your priorities are. All vehicles will get you from point A to point B. All imaging prgms will create & restore images.
Personally, I want the MOST RELIABLE imaging program I can find. And I feel comfortable I can figure out how to USE it if it's not the most user-friendly.
Admittedly, Ghost is not the most user-friendly imaging prgm, but I have created hundreds of images and restored dozens, without a single problem. Not one. That's what I call RELIABILITY.
The question isn't so much WHICH imaging prgm to use, but rather that people use *some* imaging prgm .. which is far better than using none.
Regarding your bootable CD question, maybe this link will help:
