I've been trying to setup dual boot over the past few days with Kali Linux 2.0 and have finally managed to get it installed to a partition. However, when I boot up my pc it boots up straight into Windows and does not give me an option to choose which operating system to boot to. I've checked and there is a partition for grub. Does anyone have any idea on how I might go solving this? My PC is a Samsung ATIV Book 9 Lite Touchscreen 128GB. Thanks in advance!
