Hello, I recently did a dual boot with windows and ubuntu 12.1 on my hp dv6t quad core laptop. When i try to restore the computer using an iso burned cd with windows 7 on it. I get an error message saying there is no driver installed.. what do i do to get windows to recognize my driver... I have tried using 2 different disks of windows and i still cannot figure out how to get windows to find my hard drive. Any help? thank you in adnvance
