I want to install Kali Linux on my hard disk. I already have Ubuntu/win7 dual boot. When I start installing Kali Linux everything goes right, choosing  language, root's pass word ..., but after the system finished coping system's files I got a weird black screen saying system is going for halt (or something like that I can't remember well because it was too short).After that I lost the grub, I got an error saying File Not Found grub-rescue >. I retried but the same problem came up, so I installed Ubuntu again and everything is fine right now.  I would like to know the reason why I cant have Kali Linux on my hard drive though it works awesome in live mode.P.S I disabled wireless card from BIOS menu because the installation stops at detecting network interfaces step.

You could also use debootstrap to install Kali directly from Ubuntu.You may refer here: http://docs.kali.org/armel-armhf/kali-linux-arm-chroot (replace armhf with your arch).You will also have to use this installation script: https://raw.githubusercontent.com/meefik/linuxdeploy/master/assets/home/deploy/debootstrap/scripts/kaliYou should specify it in this line:debootstrap --foreign --arch $architecture kali kali-$architecture \    http://archive.kali.org/kali <place_path_to_downloaded_script_here>
