Recently I downloaded Kali Linux iso file for windows, I found no problem installing dual boot Kali Linux and Windows 8 on my Lenovo G460, but when I reboot I unable to use my Windows 8 anymore, and when I am trying to re install my Windows 8, Windows setup can't find my Hard disk, as seen on here, but when I am running my kali linux, I can see all of my Disk Drive and able to use the drives, how to fix it? any Idea?
