i found the solution,read this... NezoNezo
,you DONT need to boot by usb and you DONT need to boot with the norton recovery cd to start the NG 15.0 backup or recovery.
i found this....
A) insert the NG 15.0 recovery cd in ur cdrom(you will understand in a little)
B) Start Norton Ghost 15.0 and go to Tasks,(is on top next to view),then choose,
<<Set Up LightsOut Restore>>,press next and browse for ur recovery cd location,press next etc and let the program to finish.(set the boot menu time to 5 secs)
What you have made?You just extract the recovery cd files in ur hard disk partition,so from now on every time you will start or restart ur pc you have 2 options, start the windows normaly or start the NG 15.0 backup and recovery.
I test it,i just restart my pc and i choose the NG 15.0 and i restore my pc.
Works just fine!
