I have tried to install Kali Linux along with Windows 7 several times. I have had no problem installing Ubuntu, it works like a charm. But the issue is installing Kali Linux alongside Windows 7. After I manage to install it, and I restart the computer, Kali Linux does not show up on the boot menu. Why is that happening? I have a Asus Zenbook Prime, currently running Windows 7 oem version, I had to reinstall Windows after completing erasing the operating system before.
