Helly everybody,

i'm fairly new to ubuntu and coming from a windows enviroment, i have this question:

how do i take an image from a hd once it's configured with all the software, drivers, etc?
I know how to do this in windows, but how do you do it with an ubuntu distro?

And once i've done that, and stored it on an external hd, how would i go about to restore the image on another hd? (or the same, for that matter)

Thx in advance for all the help!!
