I have been running Kali from a live USB for about a year and when i tried to install it dual boot with the default Windows 7 OS on the HDD, the install fails at the 39% mark, i have tried formatting the patitions both using gparted as well as using the installer, neither the graphical or text installs work, but the worse part is now when i attempt to load back to my windows boot, nothing happens, the screen goes black and a blinking line appears in the top left, it just stays like that.
Does anyone know how to fix this??
