I have now got Windows 7 on my laptop. I have window7 7 professional and want to make a complete image as I have all my applications set as I like them. My laptop does not have a CD/DVD drive. I sent the system image and backups to an external USB drive. When I went to make the "system recovery disc" it would not make one because I do not have a cd/dvd drive. is it possible to make "system recovery usb stick"?. If so how?
