Why were you restoring? Was it due to a problem? Did the computer fail? Can u give us more info? What were you restoring from? Did you have a previous back up or something that you were trying to restore from? You say that you have no disk for it? Is it a laptop or is it a desk top? Many of them have a restore partition on the hdd? Was it the original os that you were trying to restore? Because if it wasn't and you're using an unlicensed version, or something like that....no one here will help you with that.
