Installing NVIDIA Drivers on Kali v2.0

I am a newbie. I want to learn more about White Hat activities, and have been going about it the hard way. Unfortunately, I am stuck.

After I updated the sources.list to the correct repositories, I finally got the proper headers and kernel.

I was missing the deb http://http.kali.org/kali sana main non-free contrib. After the apt-get update I entered:

apt-get install -y linux-headers-$(uname -r)

apt-get install nvidia-kernel-dkms

I also disabled nouveau.

Unfortunately, after my successful driver upadte, Kali will not boot.

The screen it hangs on says: OK Update UTMP about system runlevel changes.

I can ctrl+alt+del to restart but I cannot boot in.

System Specs: 16 GB Ram

256GB SSD (Kali and Windows)

2 TB HDD

I7 4790 3.60 Ghz

Has anyone had a similar problem or experience? How do I fix it?

I have limited Linux knowledge, I am just starting my education. Please speak slowly with small words so I can keep up.
