hello list i understand how to use my version of nero to back up my hard drive onto dvd disks but... once i have a selection of dvd disks with my entire hard drive contents on them what use are they? i originally intended to do this to give myself a back up of the hard drive in case of a fatal error with the drive, but if my drive had to be formatted for any reason how would i get the information from the dvd disks onto the new hard drive that i would have to put into my machine? does nero copy the whole operating system over and are the disks bootable? i have tried to get information on this from doing a google search but i don't seem to get anywhere. all help is appreciated. stephen
