I am trying to install Ubuntu 12.04 alongisde windows 7 which is already installed on my computer. I have a Lenovo Thinkpad T430s. When I perform a live boot of Ubuntu from a flash drive, I am able to connect to the internet and it seems to run fine but when I run the installer on the Ubuntu desktop, it says there are no operating systems currently installed on my computer. There is no option to install Ubuntu alongside windows. I have run boot repair and here is the resulting url: http://paste.ubuntu.com/7023830/ I am totally new to Linux and would really appreciate some help figuring this out.
