Hi There …
Welcome to Kali World or let’s say Linux Big world
things in windows was much easier  you can install a Software with few Clicks
you can install Drivers with few clicks !

but in Linux is not like that, there is always work to do commands to write simply in Linux you have to do things by your self and yes you have to learn to do it,
so windows was better ? for sure no because here we learn things and there is no virus to be scared off, with Linux everything is under control.
So let’s start
few days ago i got kali Linux 1.7 and i wanted to install Nvidia Driver
i went to docs in Kali.org and i did follow the step they write in the page of installing Nvidia drivers in Kali

So i start with
 apt-get update
Then
 apt-get dist-upgrade
and
 apt-get install -y linux-headers-$(uname -r) ! here the problem start

i got this message E: Unable to locate package linux-headers-3.14-kali1-686-pae

So i searched the web with a hope that i find the way to fix it but … no one is writing a tutorial how to fix Unable to locate package linux-headers-3.14-kali1-686-pae

most of the guys says do apt-get update before apt-get install -y linux-headers-$(uname -r)
 and that is what i did but yet i still have the problem,

so if the  issue should be fixed with apt-get update then maybe the problem here is i’m not getting all the needed updates,

So i had to Check the Repositories at sources.list
to do that go to

File system etc/apt/sources.list

this what your file may have in it “mine was like that”

#

# deb cdrom:[Debian GNU/Linux 7.0 _Kali_ - Official Snapshot i386 LIVE/INSTALL $

# deb cdrom:[Debian GNU/Linux 7.0 _Kali_ - Official Snapshot i386 LIVE/INSTALL $

deb http://http.kali.org/kali kali main non-free contrib
deb http://security.kali.org/kali-security kali/updates main contrib non-free

so what i did now is adding this to line

deb-src http://http.kali.org/kali kali main non-free contrib
deb-src http://security.kali.org/kali-security kali/updates main contrib non-free

and now the file have all this Repositories

#

# deb cdrom:[Debian GNU/Linux 7.0 _Kali_ - Official Snapshot i386 LIVE/INSTALL $

# deb cdrom:[Debian GNU/Linux 7.0 _Kali_ - Official Snapshot i386 LIVE/INSTALL $

deb http://http.kali.org/kali kali main non-free contrib
deb http://security.kali.org/kali-security kali/updates main contrib non-free

deb-src http://http.kali.org/kali kali main non-free contrib
deb-src http://security.kali.org/kali-security kali/updates main contrib non-free

After i added this 2 new Repositories we have to do the update…
apt-get update
apt-get dist-upgrade
apt-get install -y linux-headers-$(uname -r)
and finally
apt-get install nvidia-kernel-dkms
now everything seems to be fine…!

unexpected!
Kali 1.0.8 is here!
The long-awaited Kali Linux USB EFI boot support feature has been added to our binary ISO builds, which has prompted this early Kali Linux 1.0.8 release. This new feature simplifies getting Kali installed and running on more recent hardware which requires EFI as well as various Apple Macbooks Air and Retina models. Besides the addition of EFI support, there is a whole array of tool updates and fixes that have accumulated over the past couple of months.

So what we get more with this new Release ?
here is a list of the change and update
