I bought a Lenovo IdeaPad with Windows 7 preinstalled. The laptop has a "OneKey Rescue System" which is able to restore the factory install of the OS. As I understand the files necessary for this restore are on the hard disk. What happens if the contents of the hard disk are deleted for some reason? Can it restore the OS install in that case? If not, shouldn't Lenovo has enclosed an install DVD with the computer which is not affected by a HDD crash?
Or should I create such a DVD myself? What happens with my Windows 7 product key if the installation files are lost?
What steps do you do to make sure you can reinstall the factory OS in case of a serious crash?
