After so much struggle and online searching I've come here. I'm trying to install Kali Linux on a partition on my laptop which is currently running Windows 8. kali runs fine with a live boot via USB but every time I install it it never boots up, During the installation I didn't know what to do when it asked if I made it my master boot or something like that. But I didn't want to risk my W8.

if you need any information which you probably will, Just ask!

Thanks in advance
