view story

http://ubuntuforums.org – I've installed ubuntu full install into an usb flash drive, along with it, I 've also install so many softwares, tweaked so many settings Now I want to backup the whole os along with it's installed softwares, tweaks, settings, etc , into my laptop HDD, so if in the future, I formatted the flash drive or moving into a larger flash drive, I can easily restore the whole os, with all of it's installed softwares, settings, tweaks, etc How do I do that ? I got the latest hiren boot cd on my laptop, can I do it with it ? Or should I use remastersys instead ? Note: I installed propiertary drivers (Hardware)
