Hello The restoration procedure of Ghost, when you are using an recovery image will replace any backup bytes. So if your backup took 10GB, the restoration will replace the 10GB pattern including boot .... If your backup is clean (without virus), it will be ok. I don't remember as well, but with the boot cd i think you can use tools for hard drive : to do a "normal" format. It will be long but it will ensure no viruses. Hope it will help you
