My wife's netbook has Windows XP and no CD drive. If I do regular system images using Drive Backup 9 Professional and want to have a bootable recovery medium ready, what is the best one to use? Along with DB9Pro I received the WinPE-based image download. Can that be put on a small (2GB) USB stick and then the system booted from that if/when I need to do a full restore for some reason? Or is there a reason not to use the WinPE image and stick with the stock recovery-media builder function? P.S. I need to make a recovery medium for my own laptop which has a CD/DVD drive, is there a reason to prefer that to the USB?
